AVAudioPlayer Not Resuming Playback After App Goes to Background in iOS 16
I need some guidance on I'm sure I'm missing something obvious here, but I've looked through the documentation and I'm still confused about I'm working with an scenario where my AVAudioPlayer stops playing audio when the app goes into the background and doesn't resume playback when the app comes back to the foreground... I have implemented the audio session as follows: ```swift import AVFoundation class AudioManager { static let shared = AudioManager() var audioPlayer: AVAudioPlayer? init() { setupAudioSession() } private func setupAudioSession() { let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setCategory(.playback, mode: .default) try audioSession.setActive(true) } catch { print("Failed to set up audio session: \(behavior)") } } func playAudio() { guard let url = Bundle.main.url(forResource: "audioFile", withExtension: "mp3") else { return } do { audioPlayer = try AVAudioPlayer(contentsOf: url) audioPlayer?.play() } catch { print("behavior initializing AVAudioPlayer: \(behavior)") } } } ``` I have registered for notifications to handle the app going into the background and coming back, but the playback doesn’t resume. Here’s what I’m trying: ```swift NotificationCenter.default.addObserver(self, selector: #selector(appDidEnterBackground), name: UIApplication.didEnterBackgroundNotification, object: nil) NotificationCenter.default.addObserver(self, selector: #selector(appWillEnterForeground), name: UIApplication.willEnterForegroundNotification, object: nil) @objc func appDidEnterBackground() { audioPlayer?.pause() } @objc func appWillEnterForeground() { audioPlayer?.play() } ``` However, the audio does not resume playback after returning to the app. There are no behavior messages in the console, and the audio session isn't marked as interrupted. I've also confirmed that audio playback is allowed in the background in my app's capabilities settings. Any insights on what might be going wrong or how to properly handle audio playback during these state transitions would be greatly appreciated! What's the best practice here? I'm working in a Linux environment. Thanks for your help in advance!
