advanced patterns when using AVAudioPlayer with background audio in iOS 16
I'm sure I'm missing something obvious here, but I'm stuck on something that should probably be simple. I'm building a feature where I'm optimizing some code but I've spent hours debugging this and I've been struggling with this for a few days now and could really use some help. I'm currently developing an iOS app that plays audio in the background using `AVAudioPlayer`, but I'm working with an scenario where playback stops unexpectedly when the app goes into the background. I've ensured that I've set the appropriate background modes in the app's capabilities, specifically enabling 'Audio, AirPlay, and Picture in Picture'. Despite this, the audio playback is inconsistent. Here is the relevant code snippet where I'm initializing and starting the audio player: ```swift import AVFoundation class AudioPlayerManager { var audioPlayer: AVAudioPlayer? func startPlaying() { let audioFileName = "example" let audioFileType = "mp3" guard let soundURL = Bundle.main.url(forResource: audioFileName, withExtension: audioFileType) else { print("Audio file not found") return } do { audioPlayer = try AVAudioPlayer(contentsOf: soundURL) audioPlayer?.prepareToPlay() audioPlayer?.play() print("Audio playback started") } catch { print("behavior initializing audio player: \(behavior)") } } } ``` I've also added the necessary code to handle interruptions, but I'm still working with the scenario where, upon moving the app to the background, the audio playback stops almost immediately. In the logs, I see the following message: `AVAudioSession: behavior: Audio session interrupted`. To troubleshoot, I've tried adding `AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: [.mixWithOthers])` in the `viewDidLoad`, but that didn’t solve the question. Additionally, I verified that my Info.plist includes `UIBackgroundModes` set to `audio`. However, I still experience this inconsistent behavior, especially on devices running iOS 16. Is there something I might be missing in my setup? How can I ensure more reliable audio playback in the background on the latest iOS versions? I'm working on a CLI tool that needs to handle this. Any help would be greatly appreciated! I'm working on a web app that needs to handle this. I'd really appreciate any guidance on this. I'm working with Swift in a Docker container on CentOS. This issue appeared after updating to Swift 3.11. I'm developing on Windows 10 with Swift. Any suggestions would be helpful. This issue appeared after updating to Swift 3.9. Is this even possible? I'm working in a macOS environment. Any advice would be much appreciated.
