Swift: Keep playing sounds when the device is locked

Question

I\'m using the following code to play a sound off a URL from the internet:

var audioPlayer = AVPlayer()

...

let audioSessio         


        

Answer 1

Open your app info.plist as Source code (to edit in text mode) and add the following just after dict:

<key>UIBackgroundModes</key>
<array>
    <string>audio</string>
</array>

Answer 2

swift 2+ solution:

do {
  try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
  try AVAudioSession.sharedInstance().setActive(true)
} catch _ {
  return print("error")
}

Answer 3

first of all you should add background mode to your plist like this:

Then you should use AVAudioSessionCategoryPlayback session. Like this:

AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)

AVAudioSessionCategoryAmbient does not work in background.

Answer 4

You use wrong category, for AVAudioSessionCategoryAmbient it's normal behavior "Your audio is silenced by screen locking and by the Silent switch". Use AVAudioSessionCategoryPlayback instead.
