Hi everyone — I’m implementing the new Hearing Device Support API described here: https://developer.apple.com/documentation/accessibility/hearing-device-support I have MFi hearing aids paired and visible under Settings → Accessibility → Hearing Devices, and I’ve added the com.apple.developer.hearing.aid.app entitlement (and also tested with Wireless Accessory Configuration: https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.external-accessory.wireless-configuration ). com.apple.developer.hearing.aid.app xxxxx but the app won't even compile with this entitlement Problem NotificationCenter.default.addObserver(...) for pairedUUIDsDidChangeNotification never fires — not on app launch, not after pairing/unpairing, and not after reconnecting the hearing aids. Because the notification never triggers, calls like: HearingDeviceSession.shared.pairedDevices always return an empty list. What I expected According to the docs, the notification should be posted whenever paired device UUIDs chan

I'd like to set my macOS app written in Swift as default app when opening .mp4 file. I think I can do it with setDefaultApplication(at:toOpen:completion:). https://developer.apple.com/documentation/appkit/nsworkspace/3753002-setdefaultapplication However, permission error occurs when I use it. The error is: Error Domain=NSCocoaErrorDomain Code=256 The file couldn’t be opened. UserInfo={NSUnderlyingError=0x6000031d0150 {Error Domain=NSOSStatusErrorDomain Code=-54 permErr: permissions error (on file open)}} I tried to give my app full-disk access, but it didn't work. I also tried to use setDefaultApplication(at:toOpenFileAt:completion:), then it works with no error, but it effects on only one file. What I want to do is to set my app as default app of all .mp4 files. How do I achieve this? My code is like below: let bundleUrl = Bundle.main.bundleURL NSWorkspace.shared.setDefaultApplication(at: bundleUrl, toOpen: .mpeg4Movie) { error in print(error) } Thank you.

Is there a way to display a .icon file in SwiftUI? I want to show the app icon in the app itself but exporting and including the app icon as a PNG feels redundant. This would consume a lot of unnecessary storage especially when including a lot of alternative app icons. There has to be a better way Otherwise I would file a feedback for that Thank you

Hello, I'm trying to adopt the new BGContinuedProcessingTask API, but I'm having a little trouble imagining how the API authors intended it be used. I saw the WWDC talk, but it lacked higher-level details about how to integrate this API, and I can't find a sample project. I notice that we can list wildcard background task identifiers in our Info.plist files now, and it appears this is to be used with continued tasks - a user might start one video encoding, then while it is ongoing, enqueue another one from the same app, and these tasks would have identifiers such as MyApp.VideoEncoding.ABCD and MyApp.VideoEncoding.EFGH to distinguish them. When it comes to implementing this, is the expectation that we: a) Register a single handler for the wildcard pattern, which then figures out how to fulfil each request from the identifier of the passed-in task instance? Or b) Register a unique handler for each instance of the wildcard pattern? Since you can't unregister handlers, any resources captured by the hand
