You're right, it still doesn't work. I switched to use updateApplicationContext when testing on the simulator, and figured one day it'll work again.

Do you need to enable background processing?

I've had some success by moving the synthesizer out as a global property. var synthesizer = AVSpeechSynthesizer() class TextToSpeechPlayer: NSObject { //private var synthesizer = AVSpeechSynthesizer() override init() { super.init() prepareAudioSession() synthesizer.delegate = self } deinit { disableAudioSession() }

Just call it directly. // it appears handleActiveWorkoutRecovery isn't called, so we are updating the name, and calling it directly. func checkForActiveWorkoutSession() { HealthStoreManager.shared.healthStore.recoverActiveWorkoutSession { (session, error) in if let session { Crashlytics.crashlytics().record(error: NSError(domain: "Workout Recovery", code: 00, userInfo: nil)) WorkoutFactory.shared.restoreSession(session) } } }
