I didn't really find anything in Apple docs on how to debug my extension using Xcode (so not saying it doesn't exist). I found a current Stack post on it, with several devs all stuck. In 2024 someone said run the Preview Extension, select Finder as the test app, then in a Finder window select a file of the correct type and tap space. Nothin happens when I do this (I get the file icon showing). Suggestions most welcome!

Hey, is it possible to test with an Xcode test build if the subscription notifications are correctly being sent to the backend? Currently nothing appears on my backend after subscribing. For some reason i can also subscribe multiple times to the same product. It looks like nothing is being saved anywhere which is why I also can't cancel a test subscription. All of this was fairly easy and possible when setting up the google play version of our app.

I'm having a lot of trouble getting my icon working with XCode26 and Icon Composer. <TL;DR> The icon sucks </TL:DR> Why does it suck? 4 main issues plague me when I compare the new icon with the existing icon. The colors are washed out. I can't have a transparent background. The size of the icon is wrong. I can't use the old icon on pre-Tahoe macs. It's Tahoe or bust! Here's a comparison between the two icons: If I add any Liquid Glass effects to the icon, it just looks bad. Any more of a gradient behind the image makes the image fade out. Adding specular highlights just throws a ring around the upper and lower sections that doesn't seem to fulfill any purpose. Blur doesn't seem to do anything. And I can't get rid of the background at all. It must be there. The biggest problem is the size. The new icon doesn't just look smaller, it is smaller! I measured the width and the new icon is 19.5% smaller. I did this by setting the finder view to 128x128, grabbing the screen shot, and using Acorn to measure the width from the left red edge to the right blue edge. The icns file is 256 pixels across which makes sense as I'm on a 4K monitor at 2x resolution. The icon file is 206 pixels. Doing the same with the finder set to 256x256 shows the same reduction. When I look at Icon Composer, it's showing me that the icon is fitting in perfectly with the guidelines. The graphic artist I hired years ago did a great job! So somehow there is a border being added to the icon file that shrinks the image down, and I can't get rid of it nor make the icon bigger. So I'm stuck. I've tried the various tricks to get both the icns and icon files to be added to the build such that pre-Tahoe macs see the old icon, and it either breaks on Tahoe or breaks on the pre-Tahoe. I can't get both. I don't think there's a solution to this, I'm just documenting my frustrations. The Mac was fine before this, why change something that works?

We have the following step before running any tests on CI machine: xcrun simctl shutdown all && xcrun simctl erase all It was working perfectly before Xcode 26.1. On Beta 3 it was doing it for 15 min every time. When updated to RC1, the tests with cached build are fast (clean goes up to 10 sec), but the package tests clean is still going up to 15 min every time. We did xcrun simctl runtime dyld_shared_cache update --all as advised but it's helping only temporarily. Is this going to be fixed in the official release?

In macOS, when using UNMutableNotificationContent to send notifications, clicking on the notification (or the buttons on the notification) will automatically activate the window. How can this be prevented? Clicking on the notification only triggers the click event and does not activate the window.

I'd like to start a subprocess from an Xcode extension. My prototype performCommandWithInvocation method looks like this: - (void)performCommandWithInvocation:(XCSourceEditorCommandInvocation *)invocation completionHandler:(void (^)(NSError * _Nullable nilOrError))completionHandler { NSTask*task= [[NSTask alloc]init]; [task setExecutableURL:[NSURL fileURLWithPath:@"/bin/sh"]]; //option A: [task setArguments:@[@"-c",@"echo hello from sh"]]; //option B: [task setArguments:@[@"-c",@"/usr/bin/python3 -c 'print(\"hello from python3\")'"]]; [task launch]; [task waitUntilExit]; int status=[task terminationStatus]; printf("status: %d\n",status); completionHandler(nil); } So there's two options there: option A, or option B. (Uncomment to taste.) Option A does work. /bin/sh starts, and runs echo, and it prints hello to its stdout. I was foolish enough to let this convince me that this whole thing might be a goer. Option B does not work. I get an error: xcrun error: cannot be used with in an App Sandbox. Which is annoying, as virtually all of the scripts I want to run are written in Python, and I'd quite like this to be an option. How do I fix this? I tried removing the App Sandbox settings from my extension, but then Xcode refused to load it. I added Read/Write permissions to all the File Access settings in the App Sandbox section, even though most of them sounded irrelevant, but no improvement. Then I ticked every tick box I could find. My extension can debug, it can JIT, library validation is off, it can use the camera and access my photos and read the audio and my contacts and open sockets in any direction it wants and goodness knows what else. But it seems it still can't run python. How do I make this work? --Tom

I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData. My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).

Issue : When creating a new project in Xcode 26.0 and adding a Share Extension target without modifying any code, the app crashes upon displaying the extension screen with the following error: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The layout constraints still need update after sending -updateConstraints to <_UINavigationBarTitleControl: 0x105b9cc00; frame = (0 0; 0 0); layer = <CALayer: 0x10b834270>>. _UINavigationBarTitleControl or one of its superclasses may have overridden -updateConstraints without calling super. Or, something may have dirtied layout constraints in the middle of updating them. Both are programming errors.' Environment : Xcode 26.0 iOS 26.0 (physical device) Note: This issue does not occur when running on iOS 18.3.1 (physical device). Temporary Workaround : Adding the following implementation to the isContentValid method prevents the exception from occurring: Objective-C- (BOOL)isContentValid { // Do validation of contentText and/or NSExtensionContext attachments here if (@available(iOS 26, *)) { self.navigationController.navigationBarHidden = YES; } return YES; } Questions : Is there any alternative way to avoid this exception? Since this crash occurs with the default implementation generated by Xcode, is there any plan to fix it in future updates?

Using Xcode to build and deploy the app to my watch, this is what I get: “Waiting to reconnect to Apple Watch. Previous preparation error: Transport error." And then “Connecting to Apple Watch. Xcode will continue when the operation completes.” And these messages continue to switch between each other. Sometimes the watch to connect and the application starts, but more often a scenario occurs with endless reconnection. I'm using: MacOS 14.4.1 (MacBook Pro 2019; 1.4 GHz Quad-Core Intel Core i5), Xcode 15.3, Watch OS 10.2 (Apple Watch SE 1), iOS 17.1.1 (iPhone 15 Pro). Methods I tried: Connecting Macbook, iPhone and Watch to the same WIfi network; Disabling Watch (and IPhone) from the "Devices and Simulators" menu and setting up Watch (and IPhone) from the beginning. Any help?

Hi, run into this error today: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.QJh2l0/extracted/MyAwesome.app : 0xe8008015 (A valid provisioning profile for this executable was not found.) Project is an AUv3 app + extension. It builds and install fine on MacOS. It builds on iPad but can't install : that's when the error appears. Regarding provisioning files, I use Automatic manage signing and I can see that the Xcode Managed Profile looks fine an includes my iPad. The only thing I see that differ from other projects is that as an AUv3 project, I have both and App (host) and extension projects. Thus the bundle identifier for this extension project is not the same as it seems I have to use different identifiers. So app bundle id is x.y while extension is x.y.z (same x.y base)) Last but not least the project and IPA can be built fine on XCode Cloud. (Although I can't download the artifacts but it seems it's the same problem for many of us today...) macOS Version 15.4 (Build 24E248) Xcode 16.2 (23507) (Build 16C5032a) Thanks in advance for your help :)

This whole time I was convinced that Apple just re-bound my favorite keyboard shortcut to something else in Xcode 26 and I just needed to find it and re-bind it, but it looks like they've gotten rid of it altogether and I'm losing my mind. For many years, selecting a type in the Open Quickly menu (Shift-Command-O) and hitting Shift-Option-Enter would bring up a chooser that would let you move a cursor around and select which open pane to open the file in (or create a new pane.) It was so useful and made working in Xcode so fast and it really seems like it's gone for good. Has this behaviour been changed? I don't see it mentioned in "What's New in Xcode 26?"

In my code, I used the newly added class AssetPackManager in Xcode 26. When compiling with Xcode 16, it would report an error saying "Cannot find 'AssetPackManager' in scope". Swift cannot use __IPHONE_OS_VERSION_MAX_ALLOWED. How to solve this problem?

I'm running a swift script that is emitting warning lines like this /Users/work/Documents/QuGame/QuGame/BoardTurnView.swift:1:1: warning: [dead-code] Debug-only symbol static SimpleTurn.== infix(SimpleTurn, SimpleTurn) -> Swift.Bool /Users/work/Documents/QuGame/QuGame/DataNotifications+PreviewData.swift:1:1: warning: [dead-code] Debug-only symbol DataNotifications.(addConversation)(to: QUBoardModel, local: GKPlayer, opponent: GKPlayer, texts: [Swift.String]) -> () /Users/work/Documents/QuGame/QuGame/DataNotifications+PreviewData.swift:1:1: warning: [dead-code] Debug-only symbol DataNotifications.loadBlankBoard() -> () These are correctly formatted for Xcode to detect the filename, line and columns. ` Showing Recent Issues [dead-code] Debug-only symbol static SimpleTurn.== infix(SimpleTurn, SimpleTurn) -> Swift.Bool [dead-code] Debug-only symbol DataNotifications.(addConversation)(to: QUBoardModel, local: GKPlayer, opponent: GKPlayer, texts: [Swift.String]) -> () [dead-code] Debug-only symbol DataNotifications.loadBlankBoard() -> () However, when the script is run as part of the post-actions, Xcode doesn't support clicking on the warning to take you to the file. I can map from the .o to the .swift by hunting the project directory (not-sandboxed) If I run the script as part of the Run Script Phase, I cannot back track to find the fully qualified location of the file as I'm sandboxed. All I have is BoardTurnView.o, DataNotiications+PreviewData.o etc. Anyone got any suggestions?

In Xcode I've: select Product / Scheme / Edit scheme tap on Archive on the left hand side of the select post actions and + to add a new script Then in there I have added a script I want to run on the archive after its created. I'd like to be able to see the output the script churns out as it goes along but doesn't seem possible? If I just add something like echo "hello" to the start of the script then I don't see "hello" visible anywhere when I build an archive (via Product/Archive). I'm looking in the build navigator. Is there somewhere else to look or is it possible to get the logging into the navigator?

I have designed a new icon for my app/Tahoe in Icon Composer (launched from within Xcode)but I simply cannot get it to show up. The documentation for Icon Composer spends a lot of time describing how to design the icons but goes distressingly vague/silent on how one might use it. It suggests that I should drag the file to Xcode and it will guide me as to where to put it. The app continues to use the old (pre-Tahoe) icon. I don't get any change of behaviour and I don't know what to name the file. I assume that there are no other settings that I have to change. I can't find anything on the web or in Apple's documentation: maybe I'm missing something obvious! My app is a working NSDocument-based Cocoa project. Any suggestions please. Tahoe 26.0.1, Xcode 26.0.1, Apple M1 Max MBP.
