Overview

Is there an API to programmatically create a guide for iOS 14 Maps? I know third-parties are curating Guides. I'd like to programmatically create a guide.

We have developed an IOPCIFamily based custom KEXT to communicate with Thunderbolt interface storage device. This KEXT is working fine with Apple machines with Intel CPUs in all types of machines (iMac, iMac Pro and MacBooks). We tested this KEXT with Apple Silicon M1 machine where we are observing crash for the very first command we send to the Thunderbolt device. We observed that there is difference in number of bits in Physical Address we use for preparing command PRPs. In Intel machines we get 28-Bit Physical Address whereas in M1 we are getting 36-Bit address used for PRPs. We use inTaskWithPhysicalMask api to allocate memory buffer we use for preparing command PRPs. Below are the options we have used for this: options: kIOMemoryPhysicallyContiguous | kIODirectionInOut capacity: 16kb physicalMask: 0xFFFFF000UL (We want 4kb aligned memory) According to below documentation, we have to use inTaskWithPhysicalMask api to get memory below 4gb. https://developer.apple.com/library/archive/documentation/Darwin/Conceptual/64bitPorting/KernelExtensionsandDrivers/KernelExtensionsandDrivers.html#//apple_ref/doc/uid/TP40001064-CH227-SW1 Some devices can only handle physical addresses that fit into 32 bits. To the extent that it is possible to use 64-bit addresses you should do so, but for these devices, you can either use IODMACommand or the initWithPhysicalMask method of IOBufferMemoryDescriptor to allocate a bounce buffer within the bottom 4 GB of physical memory. So just want to know what's the difference between Intel and ARM64 architecture with respect to physical memory access. Is there any difference between byte order for physical memory address..?? Crash log is given below: panic(cpu 0 caller 0xfffffe0016e08cd8): "apciec[0:pcic0-bridge]::handleInterrupt: Request address is greater than 32 bits linksts=0x99000001 pcielint=0x00020000 linkcdmsts=0x00000800 (ltssm 0x11=L0)\n" Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 20C69 Kernel version: Darwin Kernel Version 20.2.0: Wed Dec 2 20:40:21 PST 2020; root:xnu-7195.60.75~1/RELEASEARM64T8101 Fileset Kernelcache UUID: 3E6AA74DF723BCB886499A5AAB34FA34 Kernel UUID: 48F71DB3-6C91-3E62-9576-3A1DCEF2B536 iBoot version: iBoot-6723.61.3 secure boot?: YES Paniclog version: 13 KernelCache slide: 0x000000000dbfc000 KernelCache base: 0xfffffe0014c00000 Kernel slide: 0x000000000e73c000 Kernel text base: 0xfffffe0015740000 Kernel text exec base: 0xfffffe0015808000 machabsolutetime: 0x12643a9c5 Epoch Time: sec usec Boot : 0x5fe06736 0x0009afbc Sleep : 0x00000000 0x00000000 Wake : 0x00000000 0x00000000 Calendar: 0x5fe067fd 0x0006569d CORE 0 recently retired instr at 0xfffffe0015971798 CORE 1 recently retired instr at 0xfffffe0015972c5c CORE 2 recently retired instr at 0xfffffe0015972c5c CORE 3 recently retired instr at 0xfffffe0015972c5c CORE 4 recently retired instr at 0xfffffe0015972c60 CORE 5 recently retired instr at 0xfffffe0015972c60 CORE 6 recently retired instr at 0xfffffe0015972c60 CORE 7 recently retired instr at 0xfffffe0015972c60 Panicked task 0xfffffe166ce9e550: 75145 pages, 462 threads: pid 0: kernel_task Panicked thread: 0xfffffe166d053918, backtrace: 0xfffffe306cb4b6d0, tid: 141 lr: 0xfffffe0015855f8c fp: 0xfffffe306cb4b740 lr: 0xfffffe0015855d58 fp: 0xfffffe306cb4b7b0 lr: 0xfffffe0015977f5c fp: 0xfffffe306cb4b7d0 lr: 0xfffffe0015969914 fp: 0xfffffe306cb4b880 lr: 0xfffffe001580f7e8 fp: 0xfffffe306cb4b890 lr: 0xfffffe00158559e8 fp: 0xfffffe306cb4bc20 lr: 0xfffffe00158559e8 fp: 0xfffffe306cb4bc90 lr: 0xfffffe0015ff03f8 fp: 0xfffffe306cb4bcb0 lr: 0xfffffe0016e08cd8 fp: 0xfffffe306cb4bd60 lr: 0xfffffe00166bc778 fp: 0xfffffe306cb4be30 lr: 0xfffffe0015f2226c fp: 0xfffffe306cb4be80 lr: 0xfffffe0015f1e2f4 fp: 0xfffffe306cb4bec0 lr: 0xfffffe0015f1f050 fp: 0xfffffe306cb4bf00 lr: 0xfffffe0015818c14 fp: 0x0000000000000000 Kernel Extensions in backtrace: com.apple.driver.AppleEmbeddedPCIE(1.0)[4F37F34B-EE1B-3282-BD8B-00009B954483]@0xfffffe00166b4000->0xfffffe00166c7fff dependency: com.apple.driver.AppleARMPlatform(1.0.2)[5CBA9CD0-E248-38E3-94E5-4CC5EAB96DE1]@0xfffffe0016148000->0xfffffe0016193fff dependency: com.apple.driver.IODARTFamily(1)[88B19766-4B19-3106-8ACE-EC29201F00A3]@0xfffffe0017890000->0xfffffe00178a3fff dependency: com.apple.iokit.IOPCIFamily(2.9)[5187699D-1DDC-3763-934C-1C4896310225]@0xfffffe0017c48000->0xfffffe0017c63fff dependency: com.apple.iokit.IOReportFamily(47)[93EC9828-1413-3458-A6B2-DBB3E24540AE]@0xfffffe0017c64000->0xfffffe0017c67fff com.apple.driver.AppleT8103PCIeC(1.0)[35AEB73B-D51E-3339-AB5B-50AC78740FB8]@0xfffffe0016e04000->0xfffffe0016e13fff dependency: com.apple.driver.AppleARMPlatform(1.0.2)[5CBA9CD0-E248-38E3-94E5-4CC5EAB96DE1]@0xfffffe0016148000->0xfffffe0016193fff dependency: com.apple.driver.AppleEmbeddedPCIE(1)[4F37F34B-EE1B-3282-BD8B-00009B954483]@0xfffffe00166b4000->0xfffffe00166c7fff dependency: com.apple.driver.ApplePIODMA(1)[A8EFA5BD-B11D-3A84-ACBD-6DB25DBCD817]@0xfffffe0016b0c000->0xfffffe0016b13fff dependency: com.apple.iokit.IOPCIFamily(2.9)[5187699D-1DDC-3763-934C-1C4896310225]@0xfffffe0017c48000->0xfffffe0017c63fff dependency: com.apple.iokit.IOReportFamily(47)[93EC9828-1413-3458-A6B2-DBB3E24540AE]@0xfffffe0017c64000->0xfffffe0017c67fff dependency: com.apple.iokit.IOThunderboltFamily(9.3.2)[11617399-2987-322D-85B6-EF2F1AD4A794]@0xfffffe0017d80000->0xfffffe0017e93fff Stackshot Succeeded Bytes Traced 277390 (Uncompressed 703968) ** System Information: Apple Silicon M1 BigSur 11.1 Model: Macmini9,1 Any help or suggestion is really appreciated.

G'day. At my office the doors are locked with an NFC reader. We carry around a little NFC tag on our key chains which will read out a number and this then will open the door if the number matches a number in the database. I am tired of carrying around the tag, people keep loosing it, forgetting it and it would be nice to open the door using a Phone - which we tend to always have on us. So I used a credit card which is NFC enabled to readout the NFC information, added this number to the database and can now open doors using my credit card. This is pretty cool. If I forget my keys (most likely they will be on the desk but silly me left the desk without them), I may have my wallet with me. Then I tried Wallet.app on my iPhone and select the same credit card. However the door doesn't open. When looking in the door software I noticed that the tags will always transmit the same number. So does my credit card. However Wallet.app will read out 4 readings (or maybe just one very long one) and they are always different. So I can not make them match with the door database. Any ideas how to make this work? Can I give somehow wallet.app an NFC number which I can then add to my door database? Or how come the credit card and the very same one in wallet.app don't match? Thanks for your help! Would be neat if I could make this work out. This will make a lot of people happy at my office! Cheers!

Hello it’s my first time to signup on apple developers account .I followed all the necessary instructions an email was sent to my mail box that payment deductions will be done in the next 48hrs since that was on Friday 8 days down the line no deductions have been made kindly advise me on the right actions to take...email..mgariservices@gmail.com

We submitted a build to testflight and received a confirmation email it was successfully uploaded. When we open testflight on our iPhone's (X, 6s) we get a message of "Could not install appname" "The requested app is not available or does not exist" Where appname is the name of the app. Its very confusing because I can see the build listed in testflight on my mobile device and can view it in iTunes connect. I also can't install prior builds that had worked successfully when I try.

I have been playing around with the new AsyncImage Api in SwiftUI I am using the initialiser that passes in a closure with the AsyncImagePhase, to view why an image may not load, when I looked at the error that is passed in if the phase is failure, the localised description of the error is "Cancelled" but this is happening before the view is being displayed. I am loading these images in a list, I imagine I am probably doing something which is causing the system to decide to cancel the loading, but I cannot see what. Are there any tips to investigate this further?

We have submitted our app as both iPhone and iPad compatible - we want to remove iPad, but can't find how to do that in the App Store Connect console - any ideas? Thanks in advance Kjell

Some hacked my itunes connect or not sure any one tried to hack via remote desktop or else. Hacker transferred my apps to his account, how can I get those apps back?

How does core bluetooth work on tvOS? Is it available for use? Any docs would be helpful?

I have TabView in ContentView and I want to add TabView for OnboardingView in OtherView, every things work, but it is throw error for TabView in OtherView like "Trailing closure passed to parameter of type 'Int' that does not accept a closure" I do not know why? Any idea? ContentView: struct TabView : View {       var body: some View{           VStack(spacing: 0){ ....... } OtherView:    VStack {     TabView {       ForEach(onboardingData) { onboardingItem in          OnboardingCard(onboardingItem: onboardingItem)       }   }   .tabViewStyle(PageTabViewStyle(indexDisplayMode: .automatic))   .indexViewStyle(PageIndexViewStyle (backgroundDisplayMode:   .always))   .foregroundColor(.white) }

I'm currently using Swift to write an independent Apple Watch app for watchOS 7+. My app uses Location Services, and in case the user doesn't allow that at first, I'd like to have a button inside my watchOS app to send my user to the part of the Settings app (inside watchOS) where he can give the appropriate permissions for the app. I know that in iOS/macOS you can use the openSettingsURLString string from UIApplication to do what I want, but it's not available in watchOS and I haven't found any equivalent resource inside the WKExtension class (normally the equivalent for UIApplication in the watchOS environment). Does anyone know if there's any way to programatically open the Apple Watch Settings app from my watchOS app? I'm asking since as far as I understand asking for Location permissions again would not work since the user has already refused to allow the permissions before, making the authorization status "denied". I understand as well that there's the possibility of showing a modal and directing the user to go to Settings and allow the use of location services (as in "Please go to Settings > Privacy > Location Services > [AppName] to allow the use of location services") but I'd like if I could direct the user there instead as one might do in iOS. The code below is what I'm trying to do - but (of course) it crashes since I'm not actually passing any system URL. .alert(isPresented: $alertVisible) { Alert (title: Text("Please allow our app to use location services in order to get Weather Data"), message: Text("Go to Settings?"), primaryButton: .default(Text("Settings"), action: { WKExtension.shared().openSystemURL(URL(string: "")!) //UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!) }),

Hello, I am wondering how one can play music videos (with the actual video playing) with the ApplicationMusicPlayer using MusicKit for Swift? There is not much documentation on this, so any help would be appreciated.

I've ran into an error with the insertRouteData function of the HKWorkoutRouteBuilder that I can't seem to find any information on. The error is "Unable to find location series 1A193D3B-AFF5-41D8-A967-B1BE08D9F543 during data insert.". It seems to only happen when trying to insert very long routes, in the most recent case it was a 5 hour bike ride with 5900 samples. I save all the route data in a sqlite table as backup and after checking out the data there isn't any red flags as to why it would not insert correctly. Has anyone seen this before and could offer some insight or point me in the right direction to find the source of the error?

I've encountered an issue where we need multiple domain associations with separate Apple Pay implementations. Briefly, we have a /.well-known/apple-developer-merchantid-domain-association already setup with Stripe, and now we need another, different version of the file to get setup with FreedomPay. FreedomPay insists this file represents a three-way relationship between all parties and I have no reason to disbelieve them. I'm wondering if anyone has encountered this or if there is a standard procedure. I'm currently trying to find documentation on the exact way Apple Pay verification interacts with this file to see if we can produce it dynamically.

I noticing that Monterey defaults to the NSWindowToolbarStyleAutomatic / NSWindowToolbarStyleUnified toolbar style, which suppresses the "use Small Size" menu item and customization checkbox. So I've set the window to use NSWindowToolbarStyleExpanded. However, the toolbar will no longer change to a smaller icon size, as it did in MacOS 10.14, 10.15, and 11.0. I've tried to set the toolbar item sizing to "Automatic" for all of our toolbar icons, but that results in bad positioning in both Regular and Small Size mode -- the height is way too big. The native size of the icon .png files are 128 x 128. What's odd is that if I resize the window with the toolbar to be wider, the NSToolbarItems in the overflow area will be displayed in the toolbar are 128 x 128, where the rest of the toolbar icons get displayed as a 32 x 32 icon. The only way to get it to layout remotely correct is to make the NSToolbarItem to have an explicit minimum size of 24 x 24 and maximum size of 32 x 32. And that USED to allow "small size", but on Monterey, it no longer does. Anyone had any success with small size icons on Monterey?

I'm trying to embed a self-built copy of the WebKit frameworks to a macOS app. Most importantly I hope to get some features to work which Safari offers, but WKWebView in macOS doesn't (getDisplayMedia, Service Workers, WebInspector). Many years ago I was successful in using a self-built WebKit copy in this Mac app, but it seems the WebKit framework got more complex since them, I guess because of WKWebView's architecture. That time I had to open the projects for the main frameworks in Xcode, select the framework bundle in the target and change the "Installation Directory" setting to the path @executable_path/../Frameworks. After building WebKit using the build script, I could use otool -L to confirm the changed installation path, which then was displayed for example as @executable_path/../Frameworks/WebCore.framework/Versions/A/WebCore I tried the same with a current WebKit build: I copied the products for WebKit.framework, WebCore.framework, JavaScriptCore.framework, WebKitLegacy.framework, WebGPU.framework and WebInspectorUI.framework to my app and added it to the "Frameworks, Libraries and Embedded Content" section in the Project's Target/General tab and selected "Embed & Sign" for each framework. In "Build Phases" I made sure that WebCore.framework and WebGPU.framework are only in the "Copy Files" phase (Destination Frameworks) and not in "Link Binary with Libraries", as WebCore is linked through the WebKit umbrella framework and WebGPU gave another error (not sure about how to deal with that framework, as in the system it's in a PrivateFrameworks subfolder). In "Build Settings" I made sure that @executable_path/../Frameworks is entered for "Runpath Search Paths" (it was already probably because of Cocoapods, together with @loader_path/../Frameworks. When I build my app, the system's WebKit version is used. Only when I add the environment variable DYLD_FRAMEWORK_PATH with value @executable_path/../Frameworks in the run scheme, the embedded self-build WebKit frameworks are used. Because of currently necessary backward compatibility my app can use the legacy WebView or WKWebView. The legacy WebView works perfectly with the embedded WebKitLegacy.framework. But if I try to open any URL in WKWebView, no content is rendered and in the console output I can see: Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::didFinishLaunching: Invalid connection identifier (web process failed to launch) Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::processDidTerminateOrFailedToLaunch: reason=4 Safe Exam Browser[21391:145678] [ProcessSuspension] 0x10c005040 - [PID=0, throttler=0x10c67d8d8] ProcessThrottler::Activity::invalidate: Ending background activity / 'WebProcess initialization' Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::shutDown: Safe Exam Browser[21391:145678] [Process] 0x7fbe89064020 - [pageProxyID=40, webPageID=41, PID=0] WebPageProxy::processDidTerminate: (pid 0), reason 4 2022-02-14 12:53:01.764074+0100 Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::processTerminated: Safe Exam Browser[21391:145678] [Loading] 0x7fbe89064020 - [pageProxyID=40, webPageID=41, PID=0] WebPageProxy::dispatchProcessDidTerminate: reason=Crash Safe Exam Browser[21391:146842] [SEBOSXWKWebViewController webViewWebContentProcessDidTerminate:<Safe_Exam_Browser.SEBOSXWKWebView: 0x7fbe88f8b1c0>] I have the impression that the web process might fail to launch because I didn't embed all necessary parts of the self-built WebKit (the product folder contains a large number of XPC, dylib and .a files). Or some additional paths have to be adjusted before building WebKit, so that the embedded frameworks/libraries are used and not the system provided ones. I also looked at the bundle of the Safari Technology Preview and can see some similarities but also differences. I would be grateful if anybody could provide me with information how to embed a self-built copy of WebKit into a macOS app. Unfortunately I didn't find any Mac open source browser using an embedded copy of WebKit to get some inspiration from.

Hi, I have a completely new release of my app coming out with a new tech stack. I noticed that only 1% of my users were on iPad so the new app was not created to be 'compatible' with iPad including how it looks on iPad. Can I release this new version of the app only for iPhone? Or because it was previously available for iPad I have to release for iPad as well? Really appreciate any support/guidance on this. Thank you!

Hi Apple engineers! We are making an iOS browser and are planing to deliver a feature that allows enterprise customers to use a MAM key to set a PAC file for proxy. It's designed to support unmanaged device so the MDM based solutions like 'Global HTTP Proxy MDM payload' or 'Per-App VPN' simply don't work. After doing some research we found that with WKWebView, the only framework allowed on iOS for web browsing, there's no API for programmatically setting proxy. The closes API is the WKURLSchemeHandler, but it's for data management not network request interception, in other word it can not be used to handle HTTP/HTTPS request well. When we go from the web-view level to the app level, it seems there's no API to let an app set proxy for itself at an app-level, the closest API is Per-App VPN but as mentioned above, Per-App VPN is only available for managed device so we can't use that as well. Eventually we go to the system level, and try to use Network Extension, but there's still obstacles. It seems Network Extension doesn't directly provide a way to write system proxy. In order to archive that, we may have to use Packet Tunnel Provider in destination IP mode and create a local VPN server to loop back the network traffic and do the proxy stuff in that server. In other word, the custom VPN protocol is 'forward directly without encryption'. This approach looks viable as we see some of the network analysis tools use this approach, but still I'd like to ask is this against App Store Review Guidelines? If the above approach with Network Extension is not against App Store Review Guidelines, I have a further question that, what is the NEProxySettings of NETunnelNetworkSettings for? Is it the proxy which proxies the VPN traffic (in order to hide source IP from VPN provider) or it is the proxy to use after network traffic goes into the virtual private network? If none of the above is considered recommended, what is the recommended way to programmatically set proxy on WKWebView on an unmanaged device (regardless of where the proxy runs, web-view/app/system)?

I spend a lot of time here on DevForums. Over the years I’ve read many posts, both good and bad. This page is my attempt at writing down what makes a good one. Hopefully some of you will find it useful. Before you read this, read the official Apple Developer > Support > Developer Forums page. If you have questions or feedback about any of the points raised here, start a new thread in the Developer Tools & Services > Developer Forums subtopic. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Quinn’s Top Ten DevForums Tips Here are my top ten DevForums tips: Is DevForums right for you? Search before you ask Keep your expectations realistic Topic, subtopic, and tags Craft a quality post Prefer text over images Include details with your questions Crash reports Cross posting courtesy Resize screenshots Include a Spinal Tap reference Close your threads Think about your title Post URLs in the clear Many of these boil down to one word: Empathy. Think about the person who’s reading your post. Can they read it? Will they understand it? Will it help them? 1. Is DevForums right for you? To quote Apple Developer > Support > Developer Forums, the Apple Developer Forums (aka DevForums) are: a great place to post questions, exchange knowledge, and connect with fellow developers and Apple engineers on a variety of development topics. DevForums is focused on developer issues. That includes the APIs in Apple’s platform SDKs, Apple tools, developer-oriented Apple services like App Store Connect, and accessory development. If you have a user-level question, you’ll have more luck over in Apple Support Communities, run by Apple Support. DevForums is focused on Apple technologies. If you’re using a third-party tool or library, feel free to ask questions about it here, but you’re more likely to find folks with relevant expertise in that technology’s dedicated support channel. If you want to file a bug report, do that using Feedback Assistant. If you want to discuss a bug you’ve already filed, DevForums is a great place for that. Make sure to include your bug number in your post. For more hints and tips on the bug reporting process, see Bug Reporting: How and Why?. 2. Search before you ask DevForums has a history stretching back to 2015. Many questions have been asked and answered here. Before you start a thread, search the forums for similar threads. For details about the search syntax, see Apple Developer > Support > Developer Forums. For a quick summary, click in the search field. Remember that DevForums is world readable and thus indexed by Internet search engines. 3. Keep your expectations realistic DevForums is a support community, including both third-party developers and various folks from Apple. No one is being paid to answer DevForums questions full time. Keep that in mind when you post. Apple provides a number of other support channels. To request such support, go to the Apple Developer > Contact Us page. One of those support channels is the code-level support provided by Apple Developer Technical Support (DTS). For more information about DTS, see Apple Developer > Support > Requesting Technical Support. DTS strives to conduct most of its business here in the forums, so that our answers are available to the entire developer community. Asking about Apple’s unannounced plans is unlikely to yield useful results. Apple folks can’t discuss The Future™, and non-Apple folks can only speculate. Apple folks can’t discuss Apple’s internal business practices. For example, we can’t answer why question — “Why did Apple do this?” or “Why hasn’t Apple done that?” — unless there’s existing documentation that offers an explanation. If you think Apple should do something differently, file a bug that explains what you’d like to see change and the rationale for that. Not everyone works the same hours as you do. DevForums is a worldwide community, so there are time zones to consider, but there’s also just individual preferences. This is especially relevant around weekends, where your reply on Friday may not be seen by other folks until Monday. Different folks use DevForums in different ways. Some folks lean in to the notification system, whereas others allocate certain times of the day, or the week, to help out. 4. Topic, subtopic, and tags DevForums organises threads by two attributes: A high-level topic and subtopic A fine-grained set of tags Folks willing to offer help often monitor a specific set of subtopics or tags, and only see threads with those attributes. To increase the odds of getting a response, choose your subtopic and tags carefully. The list of subtopics is immediately visible on the top-level page. For a list of tags and their descriptions, go to Developer > Support > Forums Tags. That’s a lot of tags! When choosing a subtopic, choose the most specific one. For example, if you have a question about SwiftUI, choose UI Frameworks > SwiftUI rather than Programming Languages > Swift. The latter is primarily focused on the Swift language itself. When choosing a tag, read the description of that tag. With so many tags there are inevitably cases where a tag doesn’t mean what you think it means. For example, the Exception Handling tag is about the rarely used Exception Handling framework, not about exception handling in general, and the description makes that clear. 5. Craft a quality post When replying, use a reply rather than a comment. Comments are best reserved for short messages, like “Thanks!” or “See this other thread.” IMPORTANT If you reply in the comments, other folks on the thread may not be notified of your reply. DevForums supports Markdown formatting, similar to that used on GitHub and by DocC. The editor UI has buttons for the most common things, like Bold and Italic, but don’t feel the need to limit yourself to that. Correct formatting is particularly important for preformatted text: Use the Inline Code button, which inserts single backquote delimiters (`), for inline text in code style: identifiers and so on. Use the Code Block button, which inserts triple backquote delimiters (```), for blocks of text in code style: code snippets, logs, and so on. After submitting your post, look it over to make sure that it reads well. If not, you have a short window where you can edit the post to fix things. 6. Prefer text over images Don’t use screenshots for data that’s essentially textual, like code snippets and logs. For example, if you want to post a log message, include that as text rather than adding a screenshot. That makes it much easier for your readers to work with the text. Use the Code Block button, which inserts triple backquote delimiters (```), to format blocks of text in code style. Reserve screenshots for situations where the issue is visual, for example: When discussing view layout problems When posting instructions to achieve some task in a GUI app, like Xcode 7. Include details with your questions When starting a thread, try to include all the relevant details in your post. If you skimp on these details, folks will have to reply asking for them, and that slows things down. Specifically, anticipate the following questions: What platform are you targeting? And what version of that platform? What version of Xcode are you using? What version of the OS are you testing on? What specific API are you using? What are the exact steps you took? If something failed, what are the symptoms of that failure? If an API returned an error, what was that error? If nothing failed, what results did you see? And what were you expecting? If you filed a bug, what was the bug number? Have you tried reproducing the issue in a small test project? What else have you tried? For more thoughts on this, see Tips on writing forums posts. Oh, and if you’re having a build problem, consider attaching a full build log. 8. Crash reports If you’re trying to get help with a crash, include a crash report. For advice on how to do that, see Posting a Crash Report. 9. Cross posting courtesy Don’t start multiple threads for the same issue. That just wastes everyones time. Sometimes this happens by accident. If that’s the case, add a comment to one of the threads redirecting folks to the other one. If you find a bunch of old threads that might be related to your issue, don’t post full replies to all of them. Pick a lead thread and post your full reply there, then reply on the other threads with a link to the lead thread. Alternatively, start a new thread and reply on all the old threads with a link to that. That’ll help focus the discussion on your specific issue. If you post your question to another support channel, provide a link to that in your DevForums question, and vice versa. That avoids folks working on a question that’s already been answered elsewhere. 10. Resize screenshots If your post includes an image, make sure it renders well. Screenshots from Retina displays are often ridiculously large. Use Preview to crop the screenshot and, if necessary, downsample it by 50% (using Tools > Adjust Size). 11. Include a Spinal Tap reference To be clear, this is a joke. While the occasional Spinal Tap reference is allowed, please don’t add one to all your posts (-: 12. Close your threads If someone replies with the answer you need, mark that as accepted. That gives them some credit and helps other folks with similar questions find that answer. If you find the answer by yourself, please post a short summary of what you did. Feel free to mark that as accepted. There’s no way to change the accepted answer. See this thread for specific advice. You can’t delete your own threads. If you accidentally post two copies of the same question, choose one as the primary and, in the other one, add a reply that links to it. Beyond that, see this thread for more advice. 13. Think about your title When creating a thread, think carefully about your title. Your title is your thread’s ‘marketing statement’, a way to entice folks to read your post. Try to summarise your issue in 15 words or less. Adding tags to your title makes it harder to read. Instead, add your tags with the tagging UI. See tip 4 for more on tags. 14. Post URLs in the clear DevForums has a list of websites you can link to at will. For example, it places no restrictions on links to Swift Forums. To link to a site that’s not on the allowlist, skip the Markdown link syntax and post your link in the clear. So, this won’t work: Apple is based in [Cupertino](https://www.cupertino.org). but this will: Apple is based in Cupertino. https://www.cupertino.org Revision History 2026-01-29 Clarified the first few paragraphs in tip 3.
