Play Audio when device in silent mode - ios swift

Question

I am creating an application using xcode 7.1, swift. I want to play an audio. Everything is fine. Now my problem I want to hear sound when the device in silent mode or muted

Answer 1

You can use AppDelegate class.

For enable sound (for audio or video) when device is in silent mode use AVAudioSessionCategoryPlayback:

func applicationDidBecomeActive(_ application: UIApplication) {

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    } catch {
        print("AVAudioSessionCategoryPlayback not work")
    }
}

For disable sound when device is in silent mode (for example when we answer the phone call) use AVAudioSessionCategorySoloAmbient:

func applicationWillResignActive(_ application: UIApplication) {

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategorySoloAmbient)
    } catch {
        print("AVAudioSessionCategorySoloAmbient not work")
    }
}

You can go through this, it will help you out

When you use following audio session categories, sounds will not be muted on iOS: AVAudioSessionCategoryPlayback,AVAudioSessionCategoryRecord,AVAudioSessionCategoryPlayAndRecord

Example

func playSound (Sound: String, Type: String) {

        //Prepare the sound file name & extension
        var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(Sound, ofType: Type)!)

        //Preparation to play
        AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
        AVAudioSession.sharedInstance().setActive(true, error: nil)

        //Play audio

        var error: NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
        }
