Swift AVAudioPlayer wont play audio recorded with AVAudioRecorder

Question

I have built an app that records an audio clip, and saves it to a file called xxx.m4a.

Once the recording is made, I can find this xxx.m4a

Answer 1

In the place where you want to use the Playback using speakers before you initialize your AVAudioPlayer, add the following code:

let recordingSession = AVAudioSession.sharedInstance()
        do{
            try recordingSession.setCategory(AVAudioSessionCategoryPlayback)
        }catch{

        }

and when you are just recording using AVAudioRecorder use this before initializing that:

do {
            recordingSession = AVAudioSession.sharedInstance()
            try recordingSession.setCategory(AVAudioSessionCategoryRecord)
    }catch {}
