When setting the mode during the configuration of an audio session in Swift, the previously configured categoryOptions get reset. For example, if you perform setMode as shown below, you will observe that all previously set categoryOptions are cleared.
Example:
try AVAudioSession.sharedInstance().setCategory(.playAndRecord, mode: .videoChat, options: [.allowBluetooth, .defaultToSpeaker])
try AVAudioSession.sharedInstance().setMode(.voiceChat)
If you need to change the mode while maintaining the categoryOptions, you have to perform setCategory once again. Although the exact reason for this behavior has not been identified, the practical impact on the application's functionality is not yet clear. Why do you think this handling is in place?
