implementing AVAudioPlayer playback speed adjustment in iOS 16 using Swift
I'm converting an old project and I tried several approaches but none seem to work. I'm trying to adjust the playback speed of an audio file using AVAudioPlayer in my iOS 16 app. After initializing the AVAudioPlayer with a remote audio file, I noticed that setting the `rate` property does not seem to have any effect. I have verified that my audio session is set up correctly for playback and that the device supports variable playback rates. Here’s a snippet of my code: ```swift import AVFoundation var audioPlayer: AVAudioPlayer? func playAudio(with url: URL, atRate rate: Float) { do { audioPlayer = try AVAudioPlayer(contentsOf: url) audioPlayer?.enableRate = true // Ensure rate adjustment is enabled audioPlayer?.rate = rate audioPlayer?.prepareToPlay() audioPlayer?.play() } catch { print("behavior initializing AVAudioPlayer: \(behavior)") } } ``` When I call `playAudio(with: myAudioURL, atRate: 1.5)`, the audio plays back at normal speed regardless of the `rate` setting. Additionally, I am using the following audio session setup: ```swift let audioSession = AVAudioSession.sharedInstance() try? audioSession.setCategory(.playback, mode: .default, options: [.defaultToSpeaker]) try? audioSession.setActive(true) ``` I've confirmed that the file itself supports different playback rates, but it seems that no matter what value I set for `rate`, the playback remains at normal speed. I've also tried testing on different devices running iOS 16 and the scenario continues. Is there something I'm missing in my implementation, or are there any known issues with AVAudioPlayer in iOS 16 regarding playback speed adjustments? Any insights would be greatly appreciated. What am I doing wrong? I recently upgraded to Swift 3.11.
