    var isOtherAudioPlaying = AVAudioSession.sharedInstance().otherAudioPlaying
      println("isOtherAudioPlaying>>> \(isOtherAudioPlaying)")
      if(isOtherAudioPlaying == false)
           {
            audioPlayer1!.play()
           }

Answer 1

I would suggest checking out Sameer's answer to this for Swift 2.0, just a few months back. Works perfectly with Swift 2.0.

let sess = AVAudioSession.sharedInstance()
if sess.otherAudioPlaying {
    _ = try? sess.setCategory(AVAudioSessionCategoryAmbient, withOptions: []) //
    _ = try? sess.setActive(true, withOptions: [])
}

Answer 2

Since the default is AVAudioSessionCategorySoloAmbient, you need to set the proper category for your app and activate it. You could use AVAudioSessionCategoryAmbient for mixing audio.

Add this in your AppDelegate.swift:

func applicationDidBecomeActive(application: UIApplication) {
  AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient, error: nil)
  AVAudioSession.sharedInstance().setActive(true, error: nil)
  // ...
}

Enjoy!

Answer 3

Defer AVAudioSession.sharedInstance().setActive(true, error: nil) till when you need to start playing audio. Starting the session immediately after the app launches stops playback on other apps.
