I want to test different types of journaling suggestions, like for example photo/video containing ones but as a developer I have no control over what's shown in the Journaling Suggestions sheet. And this makes it really difficult to develop or test any suggestion type other than "reflection". Please let us have a fake suggestions sheet that includes all kinds of suggestion types so we can test. We could toggle it under Developer settings I think.

My Apple developer certificates(4 certificates) expire soon. I'm developing an application for iOS but the application is not yet released in the App Store, only Testflight releases for private testing. Is it necessary to create 4 new certificates or can I edit the current certificates so that they don't expire soon?

Hi, my server in Melbourne Australia is getting weather forecasts from a few places around Australia. When I look at the daily timesteps that I get back, they might be something like this: "days": [ { "forecastStart": "2025-06-25T00:00:00Z", "forecastEnd": "2025-06-26T00:00:00Z", "daytimeForecast": { "forecastStart": "2025-06-25T07:00:00Z", "forecastEnd": "2025-06-25T19:00:00Z", "overnightForecast": { "forecastStart": "2025-06-25T19:00:00Z", "forecastEnd": "2025-06-26T07:00:00Z",} It doesn't matter where I ask for - Melbourne, Darwin, Perth, it always comes back the same. The documentation says that daytimeForecast is 7 am to 7 pm local and overnightForecast is 7pm to 7 am local. However, in a place like Perth 7-19Z is 3 pm to 3 am, not 7 pm to 7 am like advertised. I can see that for any given date, there are 3 maximum temperature forecasts, a 24 hour max, a daytime max and an overnight max and they differ from each other. Can anyone help me understand what's happening here? And furthermore in the example above, the 24 hour forecasts that have, for example this: "forecastStart": "2025-06-25T00:00:00Z" ... Can the 00:00:00Z be trusted literally? Or is it more the case that it's "2025-06-25" but the HMS got tacked on in a conversion?

Hi, anyone managed to make this work? https://developer.apple.com/documentation/backgroundassets Trying for past few days and can't make it work. Following their official documentation, also this video https://www.youtube.com/watch?v=M3jpgZrB1uo, but it seems I am stuck at: try await AssetPackManager.shared.ensureLocalAvailability(of: assetPack) What I did: Manifest files created, info.plist configured, asset pack created and uploaded to appstoreconnect via transporter, successfully assigned to app and ready for internal testing. Added to my code: let assetPack = try await AssetPackManager.shared.assetPack(withID: "Tutorial") try await AssetPackManager.shared.ensureLocalAvailability(of: assetPack) let videoData = try AssetPackManager.shared.contents(at: "Videos/Introduction.m4v") but no luck at all.... is anywhere any demo project available to download to compare with my project?

Good morning everyone, I am developing a Flutter app for Android and iOS. When I press a button, the app detects the location of the device (obviously with permissions already granted). On Android everything works correctly. On iOS, however, when I press the button for the first time after opening the app, the location is detected after about 30-50 seconds. On the other hand, if I repeat the operation later, the response time is drastically reduced (only a few seconds). I am using the location package (https://pub.dev/packages/location), and the code to get the location is as follows: var currentLocation = await location.getLocation(); Has anyone experienced this problem before or knows how to solve it? Thank you very much! Federico

I want to create a dynamic library for my iOS project, which would be loaded at runtime. In Xcode, there are templates available for creating a static/dynamic lib for MacOS. But under the iOS tab, there is only a "static library" template. So, I used the "static library" template and in its build settings I changed the Mach-O type to "dynamic library". Now after building it, I use the file command on the generated file and it tells me it is a dynamic lib. But the generated file still has .a extension, which is usually for static libs. I'm aware we can tell Xcode in build settings to change the .a extension to something else, say .dylib but this seems like a hacky way to create a dynamic library. What is the correct way? I am aware that standalone dylibs are not supported on iOS, and we need to wrap them in a framework. For my use case, the framework will literally be a wrapper, it won't have any source files of its own. It should only contain the dynamic lib generated from some independent codebase. I am not sure how to place the dylib in the framework.

Hi, I have an installer package that runs a postinstall script. The script can take a long time to complete, as one thing it does is copy about 10-30 GB of files using the rsync tool. We noticed on macOS 15 that the installer would fail almost exactly 10 minutes after it started. Looking in the /var/log/install.log, I see a message like this: 2025-07-01 12:54:32-07 Work-M1 package_script_service[21562]: PackageKit: Terminating PKInstallTask(pid:21573). Task has exceeded its 600 seconds of runtime. This does not happen in my testing on macOS 12 (Monterey) I have a few questions about this: A) Is this documented, and which OS introduced this? B) Is there a way a developer can extend or disable the time limit via a setting in the installer package. Or if not, is there a way end end user can disable it temporarily on their system? Thanks, Andrew

I was developing an app using a certain bundle ID, but then had to delete it (and I also removed the app ID Identifier) My question is, can I make a new app with the exact same bundle ID as I was using on the removed one? Since the old app never went into production I don't see why that would be a problem

I am using macOS’s /bin/date command, both in Terminal and via AppleScript (do shell script). I noticed inconsistent behaviour with the %N format specifier for nanoseconds: • On some Macs, date +%s%N returns numeric nanoseconds as expected. • On other Macs, the same command returns a literal N or fails when coerced to a number. • This occurs across different macOS versions and on both Intel and Apple Silicon machines. My understanding is that macOS ships BSD date, which does not officially document %N. I am trying to determine: 1. Is %N in /bin/date officially supported on macOS, and if so, on which versions? 2. If %N is not supported, what is Apple’s recommended, portable method for obtaining sub-second or millisecond timestamps in shell scripts or AppleScript across all macOS versions?

Hello, "This issue is blocking App store approval" I have tried pushing my application to Appstore. However it has been rejected on the following ground: _"As we discussed, the app uses or references the following non-public or deprecated APIs: Frameworks/CommonLibrary.framework/CommonLibrary Symbols: • _SecCertificateIsValid The use of non-public or deprecated APIs is not permitted, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms."_ I have scanned the app using "strings" tool & "otool -ov" tool. But they have come out clean. No Non-public or deprecated APIs detected. Please advise which tool can be used to scan the CL to locate where the deprecated API or non-public API lies and also how to rectify the same. Thanks Saikat Bakshi.

What is the recommended approach for distributing an XCFramework that uses common third-party dependencies (like Google Maps) when client apps may also use the same dependencies, resulting in duplicate symbol conflicts? I'm developing a closed-source SDK distributed as an XCFramework. My SDK internally uses Google Maps for mapping functionality. However, when clients integrate my XCFramework into their apps that also use Google Maps, we encounter duplicate symbol errors. What I've Tried: Static vs Dynamic Linking: Both approaches result in conflicts Static linking: Google Maps symbols compiled into my binary Dynamic linking: GoogleMaps.framework bundled with my XCFramework Build Configuration: Set "Build Libraries for Distribution" = YES Tried various linking strategies Architecture Changes: Used @implementation_only import Wrapped code with #if canImport(GoogleMaps) However, the dependencies still get linked at build time

I'm finding developing for HomeKit using the iOS Simulator utterly confounding. All of my home's actual HomeKit accessories show up fine when I run the HomeKit app I'm developing on my actual phone. But none show up when I run my app in the iOS Simulator. Maybe that's how it's supposed to be? I decided to run the HomeKit Accessory Simulator in an attempt to get something to show up in the iOS Simulator, but the accessories I've created there don't show up in the Simulator either. How do I get devices to show up in the iOS Simulator? Thanks.

I use CMake for my builds not the XCode GUI. I want to be able to build a single .app that contains both the GUI version and the command line version. I have seen products that ship both as part of the same .app (e.g. CMake) so this is clearly entirely possible, the 64k question is HOW? Right now I am building them as separate apps - lets call them DSS and DSSCL (*). The code base for each is in its own directory - each with its own CMakelists.txt file. My initial thoughts are to change the build for DSSCL so it doesn't create a bundle and then simply copy the DSSCL command and related .qm files into DSS.app/.../MacOS. However that's likely enough totally wrong, so how should I handle this please. As much detail as possible please, I am very new to macOS development -please don't assume knowledge of stuff that's second nature to you Many thanks David (*) Strictly they are DeepSkyStacker and DeepSkyStackerCL

Calling dlopen then dlclose causes an increase in the amount of memory used by the program. If I create a loop that calls dlopen / dlclose repeatedly on the same dynamic library, memory usage increases continuously. Is this a bug, or am I using dlopen / dlclose incorrectly? I can reproduce this by modifying the sample code in the Apple Developer docs Creating Dynamic Libraries. If I modify Runtime.c, changing the line void *lib_handle = dlopen(lib_name, RTLD_NOW); to add the infinite loop, as below: void *lib_handle = dlopen(lib_name, RTLD_NOW); for (int ii = 0; ; ++ii) { printf("loop %i\n", ii); int close_err = dlclose(lib_handle); printf("close error: %i\n", close_err); printf("dlopen(%s, RTLD_NOW)\n", lib_name); lib_handle = dlopen(lib_name, RTLD_NOW); } then opening and closing the dynamic library will succeed, but memory usage (as reported by top) will rapidly increase. I'm running on x86_64 macOS 13.6.6. Full code for the modified Runtime.c is attached, the rest of the code is available in the Apple Developer docs. Any suggestions? Many thanks, Chris Runtime.c

How can I get the macOS version from the Mac Catalyst version? We're building Info.plist files ourselves but we need a way to programatically (using shell scripts) derive the LSMinimumSystemVersion key needed from the iOS deployment target.

Has anyone here successfully set up macOS as a globally accessible, multiuser development server using native remote login (SSH) and VS Code Remote?

Hi everyone, after enabling CloudKit in my project, my app started showing conflicts between MusicKit and CloudKit entitlements — and now Xcode is failing to generate the provisioning profile entirely. Current issue (Signing / Provisioning Profile Failure) Xcode shows this error: “Provisioning profile ‘iOS Team Provisioning Profile: team8.groovefy.dev’ doesn’t include the entitlements: com.apple.developer.media-library, com.apple.developer.music-user-token, com.apple.developer.musickit, com.apple.developer.playable-content, com.apple.security.exception.mach-lookup.global-name” Automatic signing fails, and Xcode cannot create or update the provisioning profile. This started right after CloudKit was enabled in the project. Context Before enabling CloudKit, MusicKit worked normally, including Apple Music authentication and playlist creation. After activating CloudKit capabilities: MusicKit stopped generating the Apple Music user token Playlist creation broke Now the provisioning profile cannot be rebuilt because the required MusicKit-related entitlements are no longer included Even after removing CloudKit entirely, the issue persists — as if the App ID or entitlements on the server side became inconsistent or corrupted. I already tried: Recreating App Identifier Recreating provisioning profiles Resetting capabilities Cleaning and reinitializing the Xcode project settings But Xcode still refuses to generate a valid provisioning profile that includes the MusicKit entitlements. Summary Enabling CloudKit caused MusicKit entitlements to collide, and now the provisioning profile no longer includes the required MusicKit entitlements — preventing the app from signing, running, or creating playlists. If anyone has faced this type of entitlements/provisioning corruption or knows how to reset the App ID entitlements on Apple’s side, any help would be greatly appreciated.

Hello, I currently have a live application in the iOS App Store that needs an update to start functioning again, but I've lost the source code in a hard drive failure. Is there a way to reverse engineer the currently deployed package that is live (and also a way to download it from App Store Connect)⁉️ The development change itself is just a very small change for an API route in the code itself. I could even direct an engineer at Apple to make the change in 5 minutes! Let me know if this is possible. Thanks❗️

How do I support both Liquid Glass app icon for devices running iOS 26 and a regular app icon for devices running iOS18?
