Issue playing audio with AVAudioSession

Current code:

@IBAction func sound1(sender: UIButton)
{
    var sound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Sound1", ofType: "wav")!)

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    } catch _ {
    }
    do {
        try AVAudioSession.sharedInstance().setActive(true)
    } catch _ {
    }

    var error: NSError?
    do {
        audioPlayer = try AVAudioPlayer(contentsOfURL: sound)
    } catch var error1 as NSError {
        error = error1
        audioPlayer = nil
    }
    audioPlayer.prepareToPlay()
    audioPlayer.volume = 1
    audioPlayer.play()
}

This is the current code I had before updating this project to Swift 2.

audioPlayer = nil

The issue I get when trying to run the app is this:

Cannot assign a value of type 'NilLiteralConvertible' to a value of type 'AVAudioPlayer'

It means that your variable audioplayer is not an Optional and so can not be set to nil.

Either make it an Optional then use it with try? (note the ?) without do catch, or do not attempt to set it to nil if you want to continue using try inside do catch.
