We are experiencing troubles in our organization when we want to debug iOS applications on physical iPhones and iPads. Our iPhones (iPhone 16e, iOS 18.5) are not recognized by Xcode 16.4, but in the Finder they show up fine using the USB cable. We are aware, that the communication is different and there is an ad-hoc network that gets created to exchange the device profile. Together with our IT department responsible for our security infrastructure we narrowed it down to the following reason: As we are blocking all IPv6 traffic for local networking, the iPhone cannot communicate with Xcode to make the first connection and load the device profile. As they are not planning on changing this behavior, I am reaching out to you, if there is a way to force this first handshake between Xcode and iOS device to use IPv4? Or is there any other way to enable debugging for these devices? Any ideas would be very helpful.

I am experiencing an issue where XCode reverts .xccurrentversion file in my iOS app to the first version whenever xcodebuild is run or whenever XCode is started. This means I can build the app and run tests in XCode if I discard the reversion .xccurrentversion on XCode start. However, testing on CI is impossible because the version the tests rely on are reverted whenever xcodebuild is run. The commands I run to reproduce the issue ❯ git status Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") ❯ git checkout "Path/.xccurrentversion" Updated 1 path from the index ❯ git status nothing to commit, working tree clean ❯ xcodebuild \ -scheme Scheme \ -configuration Configuration \ -sdk iphonesimulator \ -destination 'platform=iOS Simulator,name=iPhone 16 Pro,OS=latest' \ -skipPackagePluginValidation \ -skipMacroValidation \ test > /dev/null # test fails because model version is reverted ❯ git status HEAD detached at pull/249/merge Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") I have experienced such issue in 16.3 (16E140) and 16.2 (16C5032a). Similar issues/solutions I have found online are the following. But they are either not relevant or do not work in my case. https://stackoverflow.com/questions/17631587/xcode-modifies-current-coredata-model-version-at-every-launch https://github.com/CocoaPods/Xcodeproj/issues/81 Is anyone aware of any solution? Is there a recommended way I can run diagnostics on XCode and file a feedback?

We are developing a cross platform c++ application. We also use some objective-c (no swift) and specific Apple frameworks like AVFoundation, CoreML in the MacOs version of our software. We use Apple Clang as compiler when building for MacOs. As our code is primarily c++ we would like to use the latest and greatest c++ 20 features. So we are looking into using vanilla clang instead, the builds with vanilla clang seem to work fine, however our concern is that we might have overlooked possible issues that could arise. So our question is whether there are specific things we need to address when switching compilers, are there things that we need to be aware of? In the end we just want to know if switching compilers won't cause problems we can't oversee. So we would like to know if others took the same steps and what your thoughts/experiences are regarding this?

Hi! I must be missing something. I am creating a MacOS dynamic library using Xcode. I have created the library as follows: File->New Project then choose macOS 'Library' in Frameworks and Libraries. I give the Product Name "TestLib". Framework: STL (C++ Library) Type: Dynamic This creates a default library project, with one exported class 'TestLib'. There's a method "HelloWorld". And this suffices for my issue. To be able to test my dynamic library, I want to use an XCtest target. So in the project settings, I select '+', and add a 'Unit Testing Bundle': Product name: TestLibTests Language: Swift Testing System: XCTest Project: TestLib Target to be tested: TestLib I press finish, and my test target is created. Now, I think I need to have a module map. So I Add New File From Template', and choose 'Module Map'. A 'module.modulemap' is created. In the module map file, I name the module 'TestLib', and header 'TestLib.h'. So far, everything makes sense, and no errors. But here it comes... When I want to make a testcase, I need to import the module. I first built the dylib library, to make sure it's built without errors and exists. Then I switch to the TestLibTests target and want to write my first test. Simply creating an object from the TestLib class. For that, I have to import the module, so I write 'import TestLib' after the 'import XCTest' at the top. And here is where I'm stuck. No matter what I do, Xcode just gives me the error 'No such module TestLib'. This should just work, right? I should be able to unit test my library. I have spent 2 days reading the internet and trying many suggestions, but I just can't get it to work. I am currently working with Xcode 26 beta. But I tried with Xcode 16.4 and that has the same issue. What am I missing?

If you need help investigating a crash, please include a crash report in your post. To smooth things along, follow these guidelines: For information on how to get a crash report, see Acquiring crash reports and diagnostic logs. Include the whole crash report as a text attachment (click the paperclip icon and then choose Add File). This avoids clogging up the timeline while also preserving the wealth of information in the crash report. If you’re not able to post your crash report as an attachment, see Can’t Post Crash Report as Attachment below. If you want to highlight a section of the report, include it in the main body of your post. Put the snippet in a code block so that it renders nicely. To create a code block, add a delimiter line containing triple backquotes before and after the block, or just click the Code Block button. If possible, post an Apple crash report. Third-party crash reporters are often missing critical information and have general reliability problems (for an explanation as to why, see Implementing Your Own Crash Reporter). Symbolicate your crash report before posting it. For information on how to do this, see Adding identifiable symbol names to a crash report. If you need to redact the crash report, do so consistently. Imagine you’re building the WaffleVarnish app whose bundle ID is com.example.wafflevarnish but you want to keep your new waffle varnishing technology secret. Replace WaffleVarnish with WwwwwwVvvvvvv and com.example.wafflevarnish with com.eeeeeee.wwwwwwvvvvvvv. This keeps the text in the crash report aligned while making it possible to distinguish the human-readible name of the app (WaffleVarnish) from the bundle ID (com.example.wafflevarnish). Finally, for information on how to use a crash report to debug your own problems, see Diagnosing issues using crash reports and device logs. Can’t Post Crash Report as Attachment Crash reports have two common extensions: .crash and .ips. If you have an .ips file, please post that [1]. DevForums lets you attach a .crash file but not an .ips file (r. 117468172). To work around this, change the extension to .txt. If DevForums complains that your crash report “contains sensitive language”, leave it out of your initial post and attach it to a reply. That often avoids this roadblock. If you still can’t post your crash report, upload it to a file sharing service and include the URL in your post. Post the URL in the clear, per tip 14 in Quinn’s Top Ten DevForums Tips. Getting a Crash Report from the Xcode Organiser The Xcode organiser shows crash reports from customers. If you’re investigating such a crash and want to post a crash report: Navigate to the crash in the Xcode organiser. Note If you can’t see the right crash, check the filter popups at the top. In the list of crashes, secondary click on your crash and choose Show in Finder. That reveals the Xcode crashpoint document (.xccrashpoint) in the Finder. Secondary click on that and choose Show Package Contents. In the resulting Finder window, find a crash report (.crash) that accurately represents the crash you’re investigating and attach that to your forums post. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" [1] Because it’s easy to go from an .ips file to a .crash file. I usually do this by choosing File > Quick Look in the Finder. For more info about these file formats, see this post. Revision History: 2025-08-29 Added the Getting a Crash Report from the Xcode Organiser section. 2024-11-21 Added a recommendation to post the .ips format if possible. 2024-05-21 Added some advice regarding the “contains sensitive language” message. 2023-10-25 Added the Can’t Post Crash Report as Attachment section.

We registered an Apple Account and started the enrollment as company. Entered DUNS number and everything. Afterwards we got the mail, there is somthing suspicous, we have to reply to germandev@ why we want to be registered. We found out, that we had a student once who started developing an app and registered themselves with company details. This account seems to be closed, but anyhow, it is mixed now. I tried to write several times to germandev@ team, but we don't get any reply for weeks. Who else can help us? Some phone number? Thanks

How to access an additional 100 higher price point? I can only see 800 price point right now.

I'm currently exploring Instruments for profiling and tracing on macOS 15.6.1. I know there is the "network connections" instrument which records TCP/UDP information, however it seems to not include the "lo0" (loopback) interface. Is there a way to configure it so that localhost traffic is included in the recording? as the application I'm tracing uses that and I want that information to be included in traces. The documentation for network-interface-detection schema makes no mention of how it detects interfaces. Thanks in advance.

Hi, I’m debugging an issue with AddressSanitizer (ASan) on macOS. I’ve noticed that strings placed in the __asan_cstring section are aligned and padded with redzones. When I attempt to copy a contiguous block of memory (e.g., memcpy(buf, asan_cstring, 4096)), ASan throws an out-of-bounds access error. On the other hand, strings in the __cstring section do not cause this problem, likely because they are laid out contiguously without redzone padding. Could you clarify: Are strings in __asan_cstring section aligned and padded individually with redzones? Is this redzone inserted after each global string for alignment or instrumentation purposes? Does this mean that bulk memory copies over this section (even if read-only) are inherently unsafe under ASan? Is there a recommended way to safely iterate or copy memory from __asan_cstring without triggering ASan violations? Any guidance on how redzones are managed in the __asan_cstring section would be very helpful.

I have the following code snippet with a simple map and map reader that shows a pin on the map when the user selects a location struct MapReaderTest: View { @State private var loc: CLLocationCoordinate2D? = nil var body: some View { MapReader { proxy in Map { UserAnnotation() if let loc { Marker(coordinate: loc, label: { Text("Marker") }) } } .onTapGesture { position in let position = proxy.convert(position, from: .local) loc = position } } } } This snippet compiles and works perfectly fine using Xcode version 16.4 building for iOS 18.0 and running on a device. This snippet also works for me when I build using Xcode 26 Beta and run in the canvas or simulator, however it does not work when I compile using Xcode 26 and run it on a physical device(I built and tested for both iOS 18.6 and iOS 26 Beta) Has anyone else had a similar issue / have any ideas for work arounds?

I am trying to update an old UIKit/CoreData app and am (among other changes) adding CloudKit synchronization support. I enabled CloudKit (ie, set up a new CloudKit domain, enabled CloudKit, Background Mode Remote Notifications, and Push Notifications. When I did this, automatic code signing failed. (see attached for the messages). I tried creating and downloading a new provisioning profile, but that did not help. FB19742743 Can someone help me? I have absolutely no idea of what to do next to get this app signed (and hopefully back into the AppStore soon).

Hi everyone, I'm having trouble with Network Extensions capability not being included in my provisioning profiles. Here's my setup: Environment: Xcode 16.0 iOS Deployment Target: 17.0 Paid Apple Developer Program ($99/year) Problem: I'm trying to use NEHotspotConfiguration in my app, but getting this error: entitlement What I've done: ✅ Enabled "Network Extensions" in App ID capabilities ✅ Enabled "Access Wi-Fi Information" and "Hotspot" ✅ Created new provisioning profiles after enabling capabilities ✅ Cleaned build folder and rebuilt ✅ Using "Automatically manage signing" in Xcode Current status: App ID shows all capabilities are enabled Xcode shows Network Extensions capability is present But provisioning profiles still don't include the entitlement NEHotspotConfiguration fails with entitlement error Questions: Has anyone else experienced this issue? Is there a specific way to force Xcode to include the entitlement? Should I try manual provisioning profile creation? Are there any known bugs with Network Extensions in Xcode 16? Code I'm trying to use: } Any help would be greatly appreciated! Thanks,

I use spm manage swift package, now i want my macos app support arm64e,so i add arm64e in Build Srtting -> Architectures. but i got error Could not find module 'SwiftyJSON' for target 'arm64e-apple-macos'; found: arm64-apple-macos, x86_64-apple-macos Apparently, if no limit in Package.swift, SPM will only compile versions for x86 and ARM64 architectures by default. now, how should I configure SPM to compile the arm64e version? thanks

I am having similar problems to this guy on Stack Overflow over a year ago: https://stackoverflow.com/questions/77627852/functions-of-iouserscsiperipheraldevicetype00-class-in-scsiperipheralsdriverkit There are also a few questions on this forum about this object, none of which have answers. I can get my driver to match and instantiate, but nobody calls my UserDetermineDeviceCharacteristics (which does nothing, just returns kIOReturnSuccess) I can attempt to call UserSuspendServices(), UserResumeServices() or UserReportMediumBlockSize() and all of them return kIOReturnUnsupported. It doesn't matter if I've unmounted the disk or not. Is the custom driver supposed to be instantiated beside the kernel's IOSCSIPeripheralDeviceType00, or should it replace it? What should its IOProviderClass be? What should its IOClass be - IOUserService, or something else? see FB19678139 and FB19677920
