I am trying to record audio from a record button inside Keyboards View and then play it back to the user with the play button but neither its recording nor it is playing the audio.

Xcode Version: 13.2.1

Here is the error: Screenshot of Error when the record button is tapped

Below is my code for recording and playing the audio:

class AudioRecoder: NSObject, AVAudioRecorderDelegate, AVAudioPlayerDelegate {

var recordingSession: AVAudioSession!
var audioRecorder: AVAudioRecorder!
var audioPlayer = AVAudioPlayer()

func askPermission() {
    recordingSession = AVAudioSession.sharedInstance()

    do {
        try recordingSession.setCategory(.playAndRecord, mode: .default)
        try recordingSession.setActive(true)
        recordingSession.requestRecordPermission() { [unowned self] allowed in
            DispatchQueue.main.async {
                if allowed {
                    print("user has allowed")
                } else {
                    print("user has not allowed")
                }
            }
        }
    } catch {
        // failed to record!
        print("failed to record!")
    }
}

func playSound() throws {
    let url = getDocumentsDirectory().appendingPathComponent("recording.m4a")
    audioPlayer = try AVAudioPlayer(contentsOf: url)
    audioPlayer.prepareToPlay()
    audioPlayer.play()
}

func startRecording() {
    let audioFilename = getDocumentsDirectory().appendingPathComponent("recording.m4a")

    let settings = [
        AVFormatIDKey: Int(kAudioFormatMPEG4AAC),
        AVSampleRateKey: 12000,
        AVNumberOfChannelsKey: 1,
        AVEncoderAudioQualityKey: AVAudioQuality.high.rawValue
    ]

    do {
        audioRecorder = try AVAudioRecorder(url: audioFilename, settings: settings)
        audioRecorder.delegate = self
        audioRecorder.record()

        //recordButton.setTitle("Tap to Stop", for: .normal)
    } catch {
        finishRecording(success: false)
    }
}

func getDocumentsDirectory() -> URL {
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    return paths[0]
}

func finishRecording(success: Bool) {
    audioRecorder.stop()
    audioRecorder = nil

    if success {
        //recordButton.setTitle("Tap to Re-record", for: .normal)
    } else {
        //recordButton.setTitle("Tap to Record", for: .normal)
        // recording failed :(
    }
}

func recordTapped() {
    if audioRecorder == nil {
        startRecording()
    } else {
        finishRecording(success: true)
    }
}

func audioRecorderDidFinishRecording(_ recorder: AVAudioRecorder, successfully flag: Bool) {
    if !flag {
        finishRecording(success: false)
    }
}}
