I have an XPC service that embeds Python. It executes a python script on behalf of the main app. The app and xpc service are sandboxed. All seems to work just fine in the development environment but the script fails in the released version. I disabled writing pycache by setting the PYTHONDONTWRITEBYTECODE environment variable because pycache tries to write inside my app bundle which fails (I believe I can redirect the pycache directory with PYTHONPYCACHEPREFIX and may experiment with that later). Specifically this line fails in the release version only (not from Xcode): PyObject *pModule = PyImport_Import(moduleNameHere); if (pModuleOwnedRef == NULL) { // this is null in release mode only. } Any ideas what can be going wrong? Thanks in advance.

So I get JPEG data in my app. Previously I was using the higher level NSBitmapImageRep API and just feeding the JPEG data to it. But now I've noticed on Sonoma If I get a JPEG in the CMYK color space the NSBitmapImageRep renders mostly black and is corrupted. So I'm trying to drop down to the lower level APIs. Specifically I grab a CGImageRef and and trying to use the Accelerate API to convert it to another format (to hopefully workaround the issue... CGImageRef sourceCGImage = `CGImageCreateWithJPEGDataProvider(jpegDataProvider,` NULL, shouldInterpolate, kCGRenderingIntentDefault); Now I use vImageConverter_CreateWithCGImageFormat... with the following values for source and destination formats: Source format: (derived from sourceCGImage) bitsPerComponent = 8 bitsPerPixel = 32 colorSpace = (kCGColorSpaceICCBased; kCGColorSpaceModelCMYK; Generic CMYK Profile) bitmapInfo = kCGBitmapByteOrderDefault version = 0 decode = 0x000060000147f780 renderingIntent = kCGRenderingIntentDefault Destination format: bitsPerComponent = 8 bitsPerPixel = 24 colorSpace = (DeviceRBG) bitmapInfo = 8197 version = 0 decode = 0x0000000000000000 renderingIntent = kCGRenderingIntentDefault But vImageConverter_CreateWithCGImageFormat fails with kvImageInvalidImageFormat. Now if I change the destination format to use 32 bitsPerpixel and use alpha in the bitmap info the vImageConverter_CreateWithCGImageFormat does not return an error but I get a black image just like NSBitmapImageRep

I just created a new project in the newest version of Xcode as a sample project for a feedback. Bug 1 So simply what I do in every new project is create a "Supporting Files" group (not a folder because I don't want to move these files on the file system). I put the following files in this group: .entitlements file -the Info.plist (which apparently new projects don't create anymore because I don't see one). main.m Assets.xcassets In previous version of Xcode this was done with the "New Group without Folder" action (though back in the day I believe you'd get yellow folders in "New Group" and blue folder with 'New Folder" and they were separate actions.... which was actually better and much less insane IMO but that's not really important to this). In any case, "New Group without Folder" is nowhere to be found in the context menu. I finally was able to get "New Group" to appear as long as I wasn't right clicking underneath any directory. But.... New Group actually creates a New Folder, just like New Folder. So I put the .entitlements in the Supporting Files group (which is not a group, but a directory) and the app won't compile unless I fix the path in project settings because I moved the file which is most definitely not what I wanted. So we can no longer group files in the project navigator without moving them to new directories? Is this intentional behavior? It can't be, right? Bug 2 I noticed dragging and dropping to reorder files in the project navigator no longer seems to work? In previous versions of Xcode I could drag and drop to reorder files (in groups and in folders, this would work). This appears to no longer work. I just have to accept the way Xcode orders my project files?

I've been putting off entering my EU "trader status" info. I see this is published on the developer site: "Starting October 16, 2024, developers must provide their trader status to submit new apps or app updates for distribution in the European Union. To comply with the Digital Services Act, go to the Business section by February 17, 2025 to provide your trader status or your app will be removed from the App Store in the EU." So do I have to do this now (today October 16, 2024) to prevent my apps from being removed from the EU App Store (or do I have until February 17, 2025)?

I can’t submit an App Update without providing the EU trader information. I keep trying to submit this information. I upload all the documents, go through all the steps, then at the end I get the following error message: “Something went wrong. Please try again.” This is pretty frustrating. Then I had to start over...did it all again and ended up with the exact same error message. So I'm blocked from updating an app today...any advice on how I should proceed?

So I'm using AVAudioEngine. When playing audio I become the 'now playing' app using MPNowPlayingInfoCenter/MPRemoteCommandCenter APIs. When configuring MPRemoteCommandCenter I add a play/pause command target via -addTargetWithHandler on the togglePlayPauseCommand property. Now I also have a play/pause button in my app's UI. When I pause playback from my app's UI (which means I'm the active app, I'm in the foreground), what I do is this: -I pause the AVAudioPlayerNode I'm using with AVAudioEngine. I do not, stop, reset, etc. the AVAudioEngine. I only pause the player node. My thought process here is that the user just pressed pause and it is very likely that he will hit 'play' to resume playback in the near future because My app is in the foreground and the user just hit the pause button. Now if my app moves to the background and if I receive a memory warning I presume it'd make sense to tear down the engine or pause it. Perhaps I'm wrong about this? So when I initially hit the play button from my app's UI I also activate my AVAudioSession. I do this in high priority NSOperation since the documentation warns that "we recommend that applications not activate their session from a thread where a long blocking operation will be problematic." So now I'm playing and I hit pause from my app's UI. Then I quickly bring up the "Now Playing" center and I see I'm the "Now Playing" app but the play-pause button is showing the pause icon instead of the play icon but I'm in the pause state. I do set MPNowPlayingInfoCenter's playbackState to MPNowPlayingPlaybackStatePaused when I pause. Not surprisingly this doesn't work. The documentation states this is for macOS only. So the only way to get MPRemoteCommandCenter to show the "play" image for the play-pause button is to deactivate my AVAudioSession when I pause playback? Since I change the active state of my audio session in a NSOperation because documentation recommends "we recommend that applications not activate their session from a thread where a long blocking operation will be problematic." the play-pause toggle in the remote command center won't immediately update since I'm doing it on another thread. IMO it feels kind of inappropriate for a play-pause button to wait on a NSOperation activating the audio session before updating its UI when I already know my play/paused state, it should update right away like the button in my app does. Wouldn't it be nicer to just use MPNowPlayingInfoCenter's playbackState property on iOS too? If I'm no the longer the now playing app/active audio session it doesn't matter since I'm not in the now playing UI, just ignore it? Also is it recommended that I deactivate my audio session explicitly every time the user pauses audio in my app (when I'm in the foreground)? Also when I do deactivate the audio session I get an error: AVAudioSessionErrorCodeIsBusy (but the button in the now playing center updates to the proper image). I do this : -(void)pause { [self.playerNode pause]; [self runOperationToDeactivateAudioSession]; // This does nothing on iOS: MPNowPlayingInfoCenter *nowPlayingCenter = [MPNowPlayingInfoCenter defaultCenter]; nowPlayingCenter.playbackState = MPNowPlayingPlaybackStatePaused; } So in -runOperationToDeactivateAudioSession I get the AVAudioSessionErrorCodeIsBusy. According to the documentation Starting in iOS 8, if the session has running I/Os at the time that deactivation is requested, the session will be deactivated, but the method will return NO and populate the NSError with the code property set to AVAudioSessionErrorCodeIsBusy to indicate the misuse of the API. So pausing the player node when pausing isn't enough to meet the deactivation criteria. I guess I have to pause or stop the audio engine. I could probably wait until I receive a scene went to background notification or something before deactivating my audio session (which is async, so the button may not update to the correct image in time). This seems like a lot of code to have to write to get a play-pause toggle to update, especially in iPad-multi window scene environment. What's the recommended approach? Should I pause the AudioEngine instead of the player node always? Should I always explicitly deactivate my audio session when the user pauses playback from my app's UI even if I'm in the foreground? I personally like the idea of just being able to set [MPNowPlayingInfoCenter defaultCenter].playbackState = MPNowPlayingPlaybackStatePaused; But maybe that's because that would just make things easier on me. This does feels overcomplicated though. If anyone can share some tips on how I should handle this, I'd appreciate it.

Was going to add a shortcut to an app via INIntent. I followed the WWDC developer.apple.com/videos/play/wwdc2021/10232/?time=986 Steps: Created a .intentdefinition file and created an intent. Added the intent to .intentdefinition and compiled the app. Import the header file for the custom intent in the AppDelegate MyIntentname.h Have the AppDelegate conform to the protocol created in the generated code. Implement: -application:handlerForIntent: and return self (the app delegate) Run the app. Open the Shortcuts app and search for the 'shortcut' (according to the WWDC video linked above it should show up in the actions list). Doesn't show up in the list. I tried moving the build application out from Debug to my Applications folder to see if that would help the Shortcuts app find it, but it didn't. Am I missing a step/doing something wrong?

Say I want to sync a toggle in my app with SMAppService's .status property. If the status changes from my app I can track it. But if user toggles it from System Settings, I don't see a notification so then the UI in my app is out of date. The status property is not key value observable and there doesn't appear to be a SMAppServiceStatusDidChangeNotification ? I can re-read it every time my app will become active but feels kind of wrong to do it this way.

So I just updated Xcode to 16.3 and updated a project to its recommended build settings which includes "Register App Groups". So I have an outside Mac App Store app that uses app groups. Here we have an action extension. I can't debug it, can't get it to run. Nothing useful in Xcode is displayed when I try... but it looks like a code signing issue when I run and have Console open. So I try to make a provisioning profile manually and set it...didn't work. I noticed now though in signing & capabilities the group id is in red...like it's invalid, or something? This was a "macOS styled" group without the "group." prefix. So am I supposed to switch it to have the group. prefix? It makes the red text go away (no warnings or anything about app groups here, just red text). So if I change it to group. prefix..does that make an entire new container?What happens on app update for installs that don't have group. prefix? Does the system transparently migrate the group? Or Am I supposed to migrate the entire group container to the identifier with group. prefix? Also how does this affect running on older version of macOS? If I go with the "group." prefix to make the red text go away,.. what happens on macOS 11.0? Got a little more than I bargained for here after midnight.

I have an outside Mac App Store app. It has an action extension. I can't get it to run from Xcode. I try to debug it from Safari. It shows up in the menu when I click the 'rollover' button but it doesn't show up in the UI at all. Xcode doesn't give me any indication as to what the problem is. I see this logs out in console when I try to open the action extension: Prompting policy for hardened runtime; service: kTCCServiceAppleEvents requires entitlement com.apple.security.automation.apple-events but it is missing for accessing={TCCDProcess: identifier=BundleIdForActionExtHere, pid=6650, auid=501, euid=501, binary_path=/Applications/AppNamehere.app/Contents/PlugIns/ActionExtension.appex/Contents/MacOS/ActionExtension}, requesting={TCCDProcess: identifier=com.apple.appleeventsd, pid=550, auid=55, euid=55, binary_path=/System/Library/CoreServices/appleeventsd}, I don't see why the Action extension needs Apple events but I added it to the entitlements anyway but it doesn't seem to matter. The action extension fails to open.

I notice if I pop a view controller off a UINavigationController's navigation stack using the interactivePopGestureRecognizer, every so often the view controller being popped off is not being released from memory. Haven't been able to come up with a workaround or determine anything that seems to make the issue reproduce reliably. I simply log out dealloc in the view controller that is going to be popped. Push and pop a few times and notice that dealloc doesn't log out after it is being popped off. Not sure if something in the UI (other animation) that is interrupting the pop gesture's _UINavigationInteractiveTransition ... I haven't been able to track down what is retaining my view controller. When the issue happens I can see it is still in memory (I have it listen to UISceneWillEnterForegroundNotification and I put the scene in the background then move it to the foreground and hit a breakpoint). But...I can't seem to figure out what is strongly retaining the view controller. From he debugger I start setting view controller properties to nil to see if I can break a potential retain cycle I created) but no luck. I'm only able to reproduce the memory leak when I dismiss the view controller with the interactive pop gesture (not the back button). I know that's not a lot to go on but am wondering if someone has experience anything similar and has a potential workaround?

I'm looking to release an update to a Mac application. I've updated this app many times and had no issues. I haven't change any code signing related settings in the project.Now when I try to export a dev ID signed app in Organizer, I'm an error presented as a sheet:An error occurred during exportCodesign failedThe sheet has two buttons: Show Logs and & Cancel. I've filed a bug and sent the logs to Apple. If you cancel the sheet out and hit "Previous" Xcode wll crash on you.Anyone experience this and know of a solution? This is preventing me from pushing an update out to the folks.

I have an NSTableView (view based). The cells (views) have a NSImageView to display a thumbnail.Thumbnails come from the web, and I load the thumbnails lazily. My class that handles the thumbnail loading has a delegate that sends back a message like this:-(void)thumbnailCache:(nonnull MyThumbnailCacheObject*)thumbnailCache loaddedThumbnailsForURLs:(nonnull NSArray<NSURL*>*)imageURLs { //Get the row indexes for the urls...and then call....reloadDataForRowIndexes:columnIndexes //table view doesnt have columns. [self.tableView reloadDataForRowIndexes:indexes columnIndexes:[NSIndexSet indexSetWithIndex:0]]; }However the cells don't update. At first I thought it was a bug in my thumbnail loading, but a call to reloadData does update the cells properly.Wrapping the reloadDataForRowIndexes:columnIndexes: in between beginUpdates and endUpdates calls makes no difference.Does reloadDataForRowIndexes:columnIndexes: not work with view based table views? I'm tempted to just use reloadData and hope everything works out okay.

I can no longer run my app from Xcode with code signing for my Mac app. I've configured a debug provisioning profile manually and tried that but it fails, saying the embedded framework is not code signed at all.I tried "Automatic" code signing but it fails with the same error:code object is not signed at allIn subcomponent: PATH_HERECommand /usr/bin/codesign failed with exit code 1The only way I'm able to get the app to run is to turn off code signing alltogether in Debug mode. I've noticed in that case though, testing is pretty useless because my app can't event write a security scoped bookmark to disk.

Simple UIActivityViewController configured like this:NSArray *activityItems = @[linkURL]; //<--linkURL is an NSURL. UIActivityViewController *activityViewController = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];Then I present it:[self presentViewController:activityViewController animated:YES completion:nil];If I select the Mail or Messages activity the activity works as expected. But if I select the "Reminders" or "Notes" activity the view controller for those activities present briefly before automatically dismissing and logging out:: SLRemoteComposeViewController: (this may be harmless) viewServiceDidTerminateWithError: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted}Anyone know the potential cause / workaround? The completionWithItemsHandler block does not return me an error.
