AVRecorder and AVPlayer in swift - xcode

Question

All ,
I need to create a sample audio player and recorder, its not erroring but its not playing and perhaps not recording.. any ideas ?
#IBAction func Play(AnyObject)
{
println ("Play")
let path = NSBundle.mainBundle().pathForResource("171010", ofType:"m4a")
let fileURL = NSURL(fileURLWithPath: path)
player = AVAudioPlayer(contentsOfURL: outputFileURL, error: nil)
player.prepareToPlay()
player.delegate = self
player.play()
}
#IBAction func Record(AnyObject)
{
filename = "171010.m4a"
let paths: NSArray = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
var pathComponents = [paths.lastObject as String, filename as String]
outputFileURL = NSURL.fileURLWithPathComponents(pathComponents)
settings.setValue(kAudioFormatMPEG4AAC, forKey: AVFormatIDKey)
settings.setValue(44100.0, forKey: AVSampleRateKey)
settings.setValue(2, forKey: AVNumberOfChannelsKey)
recorder = AVAudioRecorder(URL: outputFileURL, settings: settings, error: &error)
recorder.delegate = self;
recorder.prepareToRecord()
recorder.record()
}
#IBAction func Stop(AnyObject)
{
recorder.stop()
println("Stop")
}
and the globals at the top are :
class MainMenu: UIViewController , AVAudioRecorderDelegate , AVAudioPlayerDelegate {
var filename: String!
var outputFileURL: NSURL!
var recorder: AVAudioRecorder!
var error: NSError?
var settings: NSMutableDictionary = NSMutableDictionary()
var player : AVAudioPlayer! = nil
Any ideas ? I don't know if its recording and creating the file. As I am getting URL is nill on the playing function. This is wired up to a storyboard with buttons. Any help within this simple stuff in swift would be brilliant.
I have changed it to this and this should work ? Can anyone advise ?
#IBAction func Play(AnyObject)
{
println ("Play")
var audioPlayer = AVAudioPlayer()
filename = "171010.m4a"
let paths: NSArray = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
var pathComponents = [paths.lastObject as String, filename as String]
outputFileURL = NSURL.fileURLWithPathComponents(pathComponents)
audioPlayer = AVAudioPlayer(contentsOfURL: outputFileURL, error: nil)
audioPlayer.prepareToPlay()
audioPlayer.delegate = self
audioPlayer.play()
}
#IBAction func Record(AnyObject)
{
filename = "171010.m4a"
let paths: NSArray = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
var pathComponents = [paths.lastObject as String, filename as String]
outputFileURL = NSURL.fileURLWithPathComponents(pathComponents)
settings.setValue(kAudioFormatMPEG4AAC, forKey: AVFormatIDKey)
settings.setValue(44100.0, forKey: AVSampleRateKey)
settings.setValue(2, forKey: AVNumberOfChannelsKey)
recorder = AVAudioRecorder(URL: outputFileURL, settings: settings, error: &error)
recorder.delegate = self;
recorder.prepareToRecord()
recorder.record()
}

The player needs to be an ivar so it isn't popped off the stack before playing.
Here is a github project with a functioning recorder if you need more info.
Also, the convention is to start function names with a lowercase character.
