Hi! I'm having a problem that I cannot seem to figure out. I have not made any changes to my app, yet this suddenly started happening. I think it started happening after I upgraded my phone to iOS 16.3.1, but I am not entirely sure. Pseudocode: // (1) initialise player let player = MPMusicPlayerController.applicationMusicPlayer // (2) ..later, a button is pressed and we call play() player.play(myAlbumId) // (3) a background timer runs, which will ensure we are playing for 30 seconds, and pausing for 60 seconds (this is a workout app): self.timer = Timer(timeInterval: 1.0, target: self, selector: #selector(togglePauseIfNeeded), userInfo: nil, repeats: true) RunLoop.current.add(self.timer!, forMode: .common) // (4) Now, the problem occurs when the timer triggers play, the second time we are playing music (ie, it works the initial time, but in that case, play was triggered by a button press (step 2)). // So when the timer now calls player.play(), we see this error: "[SDKPlayback] applicationController: xpc service connection interrupted" player.play() Interestingly, if I manually hit play just a few seconds before the timer would have called "play" (at step 4), it works fine. Any thoughts or help on this would be highly appreciated! <3

I'm trying to run this example project: https://developer.apple.com/documentation/HealthKit/building-a-multidevice-workout-app When I run it on my device (iPhone 16 Pro and Apple Watch Ultra 2) I get this error: -[SPRemoteInterface _appRecoverAnyExtendedRuntimeSession:]_block_invoke:4350: Got no sessions back from -[CSLSSessionService existingRunningSessions:] or -[CSLSSessionService existingScheduledSessions:] after receiving a PUICInitializeSessionServiceAction I start the workout from my phone, which successfully starts the workout on the watch. But this callback is never triggered on the phone: healthStore.workoutSessionMirroringStartHandler { // not happening } This makes it difficult to learn the mirroring workout technique. I'm using Xcode 16.3 and Mac OS 15.4.1. Any help appreciated!
