Hello, Back in January 2024, I filed a bug report regarding a cache being kept by the macOS Wallpaper Agent. This cache contains every image ever set as a users wallpaper, and at the time the issue was reported, it never cleared, leaving hundreds of gigabytes wasted on users disks in some cases. FB13536275 This issue was ultimately fixed in macOS 15.1 beta 6, and remained fixed for the duration of macOS 15. The fix was excellent - the cache was reduced to storing just 2-3 days worth of images. Sadly, we've discovered that this issue is back in macOS Tahoe. The cache has moved locations, and once again is not clearing. We have filed this bug again, less than a year after it was first fixed: FB20636593 We develop an app called 24 Hour Wallpaper that keeps the wallpaper in sync with the time of day. This necessitates that the app regularly changes the wallpaper, which sadly now results in an infinitely growing and useless cache of BMP files generated by the system. As we waited 10 months for this to get fixed the first time, we expect to wait at least that long to get it fixed again, and have no confidence that it will stay fixed because the last fix lasted less than a year. This leaves us in a bad position, as people can't use our app without the cache growing arbitrarily and ultimately completely filling their disk. We've already had customers call Apple to complain about this, and the good news is that the support agents understand that this is a problem with macOS, not with our app. What we've decided to do is add a feature to the app that monitors the size of this cache and periodically deletes it. We're required to get the users permission the first time to do this, but after that the permission is cached, so the app can keep the cache folder clean regardless of if macOS is doing it's job or not. We haven't seen any side effects or problems as a result of doing this. We've seen other apps like CleanMyMac do this without any problems. We're wondering if there is anything we should be aware of regarding this caches behavior before releasing this flushing feature. Thanks for your time, -josh

Issue with App Clip Card Showing "App Clip unavailable" for DIGI LIVE App In my DIGI LIVE application, I have an App Clip configured for iOS 17.6+ (the file exceeds the 15 MB limit), and I have made all the necessary preparations for the App Clip to work correctly. However, the App Clip card constantly displays an "App Clip unavailable" error for various users (depending on their system language). The URL associated with the App Clip invocation is: https://ar.digi-live.de The AASA file is located at /.well-known/apple-app-site-association and contains the required fields for the App Clip: { "applinks": { "details": [ { "appIDs": ["N9QR6LF765.de.digilive.app"], "components":[ { "#": "no_universal_links", "exclude": true, "comment": "Matches any URL whose fragment equals no_universal_links and instructs the system not to open it as a universal link" }, { "/": "*", "comment": "Matches any URL like ar.digi-live.de" } ] } ] }, "appclips": { "apps": ["N9QR6LF765.de.digilive.app.Clip"] } } If I use the default App Clip link (https://appclip.apple.com/id?p=de.digilive.app.Clip) to launch it, the "App Clip unavailable" error no longer appears. But if I delete the App Clip from the settings, the error comes back, and it can only be launched again using the default link. It feels like the problem is with the App Clip loading at the moment the App Clip card is triggered — it simply fails to load. Video https://storage.yandexcloud.net/mmrs/files/digilive/IMG_2259.mp4

Hello, I would like to understand the update behavior for App Clips. Let's consider a scenario where a user has an App Clip on their device from a previous interaction. If I, as the developer, then publish a new version of the App Clip to the App Store, what is the expected behavior? My main questions are: Will the App Clip be automatically updated in the background? Or, is user action required to get the new version, for example, by deleting the old one and re-launching it from a Smart App Banner or QR code? Any information on this process would be greatly appreciated. Thank you.

Our app uses a 24-hour DeviceActivityMonitor repeating schedule to send users notifications for every hour of screen time they spend on their phone per day. Notifications are sent from eventDidReachThreshold callbacks at 1, 2, 3, etc, hour thresholds to keep them aware of their screen time. We have recently received an influx of emails from our users that after updating to iOS 17.6.1 their DeviceActivityMonitor notifications are saying their screen time was much higher than what is shown in DeviceActivityReport and their device's Screen Time settings. These users have disabled "Share Across Devices" - but I suspect the DeviceActivityMonitor is still getting screen time from their other devices even though that setting is turned off. Has anybody else noticed this, understands what is causing this, or could recommend a fix that we can tell our users to do?

Noticing a few issues with Screen Savers in macOS Tahoe developer beta 1 : The command open x-apple.systempreferences:com.apple.ScreenSaver-Settings.extension no longer works to open the Screen Savers preference pane. The reason? There is no longer a Screen Saver preference pane - it still exists, but it's now a Modal dialog (that can not be resized) that is opened from within the Wallpaper preference pane, by clicking a button. Something funny is happening with legacyScreensaver - I think that ScreenSaverView.Init(frame:isPreview) may be passing wrong values, e.g. the isPreview boolean is false in Preview mode? I've submitted Feedback # FB17895600 about some of these, and will report back more as I figure things out. Please feel free to add to this thread, thanks!

Hello, I’m developing an app for both iOS and macOS using Mac Catalyst. On the iOS target, the DeclaredAgeRange framework works fine: I enabled the capability, set the entitlement, and can call the APIs successfully. However, when I build the Mac Catalyst target, I get compile-time errors because DeclaredAgeRange cannot be imported. Environment Xcode 26.0.1 Deployment Target (iOS): 13.0 Mac Catalyst target enabled (same bundle ID, same source code base as iOS version) iOS build works well with DeclaredAgeRange What I tried Added the Declared Age Range capability in Signing & Capabilities for iOS target → works fine. Tried setting Mac Catalyst Deployment Target to macOS 15.0+ and rebuilding → still failed to import. Because it didn’t help, I reverted and removed the separate macOS target setting. On Catalyst, the module simply isn’t available (import DeclaredAgeRange fails). From Apple’s documentation, my understanding is that DeclaredAgeRange should also be supported on Mac Catalyst (SDK 26+). But in practice I cannot import it in my Catalyst build. Questions Is DeclaredAgeRange actually supported on Mac Catalyst right now? If so, are there additional setup steps (capabilities, entitlements, provisioning, etc.) specific to Catalyst? Has anyone successfully imported and used DeclaredAgeRange in a Catalyst project? Any guidance or confirmation would be greatly appreciated. Thanks in advance.

Hi all, I'm trying to add Spotlight support to a macOS app that handles custom virtual machine bundles with the .vpvm extension. I’ve followed the current documentation and used the modern CSImportExtension approach with a Spotlight Importer extension target. Here’s what I’ve done: App Info.plist: Declared com.makeprog.vpvm as a UTI conforming to com.apple.package. Registered it under UTExportedTypeDeclarations and CFBundleDocumentTypes. Spotlight Importer Extension: Added a new macOS target using the Spotlight Import Extension template. Set the NSExtensionPointIdentifier to com.apple.spotlight.import. Used CSSupportedContentTypes = com.makeprog.vpvm. Implemented a minimal update(_ attributes:forFileAt:) method that sets displayName, title, and contentDescription. Other steps: Verified that the .appex is embedded under Contents/PlugIns/. Confirmed it appears in mdimport -e output with correct UTI. Used mdimport -m -d2 -t /path/to/file.vpvm, but I still get: Imported '/path/to/file.vpvm' of type 'com.makeprog.vpvm' with no plugIn. The extension is never invoked. I’ve also tried: Ensuring the .vpvm file is a valid directory bundle. Restarting Spotlight / rebuilding index. Ensuring the app and extension are properly signed. Tried installing the app in test virtual machine Question: Has anyone successfully used CSImportExtension for custom UTIs? Is there something additional I need to do for the extension to be recognized and triggered? Any advice or examples would be greatly appreciated! Thanks in advance.

The name of our app is a portmanteau, and Siri is getting it slightly wrong. It’s putting the emphasis on the second and fourth syllables instead of the first and third. Kind of like if someone starting singing /tinˈeɪʒd muˌtent/. It’s just wrong enough to be funny. It still recognizes the correct name when someone says “hey Siri”. We’ve already tried adding CFBundleSpokenName and INAlternativeAppNamePronunciationHint to info.plist, but neither is changing how Siri says it. We can’t put it in AppIntentVocabulary.plist because we don’t know the key path for the app name.

I implemented AlarmKit framework to my app. It works fine when the device's screen is off. but it doesn't fire when the screen is on. No sound, No dynamic Island widget. what's wrong... is this just me? I tried other apps on appstore and they worked fine. maybe is it cause they were built with SwiftUI? I'm a flutter developer. just cause my app is non native could this happen... I'm so frustrated.

Hello, developers! I’m interested in adding my native language and flag to iOS, iPadOS and MacOS. Could you please recommend a solution or provide some valuable advice on how to achieve this? I’d greatly appreciate your assistance. Thanks!

Hello Team, We are currently experiencing a challenge deploying our application to the production environment. This is because the previous deployment was done using an old account, whereas we have now created a new organizational account that we are using to deploy the updated and modified version of the application. Kindly advise on the best practice to resolve this and proceed with the deployment.

Hi, I'm trying to add an extension to my app on iOS 26. I've followed the instructions on https://developer.apple.com/documentation/extensionfoundation/adding-support-for-app-extensions-to-your-app and made it as far as being able to launch the extension: let monitor = try await AppExtensionPoint.Monitor(appExtensionPoint: .localWebServerExtension) currentIdentity = monitor.identities.first if let currentIdentity = currentIdentity { let myConfig = AppExtensionProcess.Configuration(appExtensionIdentity: currentIdentity, onInterruption: { NSLog("extension was terminated") }) myProcess = try await AppExtensionProcess(configuration: myConfig) myConnection = try myProcess?.makeXPCConnection() } None of these calls throw, and when I examine myProcess from inside that code, it seems to be normal (there's a pid, for example). Yet the code inside my extension seems to not be executed: breakpoints are not triggered, NSLog() calls do not appear on the console. The onInterruption() callback is also not triggered, or at least it does not appear on the console either. I've probably missed something obvious, but what could it be?

Hello all, I'm developing a Mac app and need to read the content of incoming SMS, I am able to implement in android just the user has to consent and it does not read her contacts messages, so I am wondering if apple can allow this.

How can experimentation and testing calling the AgeRangeService.shared.requestAgeRange() functionality be recreated easily? The very first time I ran this the OS popped up a dialog, however it won't do so again, even after the app is deleted and the device re-started. If one navigates to Settings/User/Personal Information/Age Range for Apps/Apps that have requested your age range appear here. Then the names of apps appear here even after the app has been deleted. Therefore how can it be removed from this section? Erasing and resetting the phone will presumably reset things back to a state such that the dialog can be presented again. But doing that and having to wait for that to complete each development or test run is impractical. Is there an alternative?

I am building a screen time management app. It has the main app target, and then three extensions - those are the four targets in Xcode. The three extensions are: Shield Device Activity Monitor Device Activity Report Extension I requested "Family Controls (Distribution)" capability from Apple for the main app target / bundle ID, and it got approved. Do I need it for the extensions too? Because previously I had "Family Controls (Development)" for the extensions...

Hi, I am just wondering if there is any option to protect my endpoints that will be used by Message Filtering Extension? According to the documentation our API has 2 endpoints: /.well-known/apple-app-site-association /[endpoint setup in the ILMessageFilterExtensionNetworkURL value of the Info.plist file] that the deferQueryRequestToNetwork will request on every message Since all requests to these 2 endpoints are made by iOS itself (deferQueryRequestToNetwork), I don't understand how I can protect these endpoints on my side, like API key, or maybe mTLS. The only way that I found is white list for Apple IP range. Is there other methods for it?

Hi, I’m trying to open a GPX file (route.gpx) from the Files app on my iPhone using my app (e.g., Aqua Map). Since the latest iOS update (iOS 26), when I long-press the file and tap “Open with…”, my app does not appear in the list anymore. I’ve checked that my app has the correct permissions for Files and Folders. I’m wondering: Is this a user-side issue (Settings on iPhone)? Or does it require developer-side changes in the app (Info.plist / UTI declarations) to make .gpx files appear in “Open with…” or “Share” menus? What is the proper way to make my app appear as an option to open GPX files in Files.app on iOS 26? Thanks in advance!

We are planning on renaming our app. The new name is not like the current name. It will be renamed in the App Store as well as the App display name. Yet, we still want new and existing users to be able to find the app by using the old name in search/spotlight under iOS. A great example of this is entering Twitter to find the X app and it shows up in the App section in the Spotlight search. Are there any guidelines, settings, or tricks for doing this? Some have suggested adding a Spotlight search term but that will not have it show up in the App section I fear.

It looks like Apple has added some new API(s) to SFSpeechRecognition My app, which is currently listed on App Store does feature speech recognition. Yet, trying to use it under iOS 18.0 throws errors: -[SFSpeechRecognitionTask localSpeechRecognitionClient:speechRecordingDidFail:]_block_invoke Ignoring subsequent local speech recording error: Error Domain=kAFAssistantErrorDomain Code=1101 "(null)" What happens is that after several words are transcribed and displayed, the next sentence results in previous words disappearance. That's probably what that portion of the error text - "Ignoring subsequent local speech recording error: Error Domain=kAFAssistantErrorDomain Code=1101 "(null)" means. The problem occurs ONLY when the app is running under iOS 18.0 Even when it's compiled in Xcode 16.0 using iOS 17.5 everything works fine. Any suggestions?
