After searching for a few days, i have come to know that iOS doesn't allow recording in background. Through recording continues when it has started in foreground and goes to background.
Came to know that, "This is a new a privacy protection restriction introduced in 12.4" When trying to start recording from background, we get “AVAudioSession.ErrorCode.cannotStartRecording” error.
What do i need: our application needs to starts recording audio and transmit it while in background when user presses an external button i.e. PTT button of a BLE device.
It seems there are several similar issue posted in this forum but neither could i find any plausible solution nor got any specific documentation from Apple.
Requesting to help me out or at least please provide me a specific documentation stating "background recording is not possible".
And if any workaround exists, please suggest.
P.S. we are using **AVAudioSession.sharedInstance().setCategory(.playAndRecord, mode: .spokenAudio, options: [.mixWithOthers, .allowBluetooth, .allowBluetoothA2DP, .duckOthers]) **
