Audio playback issues with AVPlayer on iOS 16.2 during background mode
I'm upgrading from an older version and I'm experiencing an issue with audio playback using AVPlayer on iOS 16.2 when the app enters background mode... The audio plays perfectly in foreground mode, but as soon as I switch to another app or lock the screen, playback stops unexpectedly. I've implemented the necessary background modes in the project settings, specifically enabling 'Audio, AirPlay, and Picture in Picture'. My AVPlayer is configured as follows: ```swift import AVFoundation class AudioPlayer { var player: AVPlayer? func setupPlayer(with url: URL) { player = AVPlayer(url: url) let item = AVPlayerItem(url: url) player?.replaceCurrentItem(with: item) } func play() { player?.play() } } ``` I also implemented the following to handle audio interruptions: ```swift NotificationCenter.default.addObserver(self, selector: #selector(handleInterruption), name: AVAudioSession.interruptionNotification, object: nil) @objc func handleInterruption(notification: Notification) { guard let userInfo = notification.userInfo, let typeValue = userInfo[AVAudioSessionInterruptionTypeKey] as? UInt, let type = AVAudioSession.InterruptionType(rawValue: typeValue) else { return } if type == .began { player?.pause() } else if type == .ended { player?.play() // This is where I expect it to resume playing } } ``` However, when I test it, the audio does not resume playing after coming back to the app, and I get a log message saying "AVAudioSessionInterruption ended without resuming". I've also tried setting the audio session category to `.playback` before starting playback: ```swift try? AVAudioSession.sharedInstance().setCategory(.playback, mode: .default) try? AVAudioSession.sharedInstance().setActive(true) ``` What could be causing this issue? I'd appreciate any insights or best practices for properly handling background audio playback in iOS 16.2. I've been using Swift for about a year now. I'd really appreciate any guidance on this.
