音声を録音(.wavで)するアプリで、録音ボタンを押すと、下記のエラーが出てしまいます。  
教えていただける方がいましたら、よろしくお願いいたします。ちなみに、音声の拡張子なのですが、.cafの場合はエラーになりません。しかし今回は.wavで保存したいです。

追記 エラーが出る場所は以下のとおりです。

```

    class ViewController: UIViewController, AVAudioPlayerDelegate, AVAudioRecorderDelegate {
    
    
    
        @IBOutlet weak var PlayBTN: UIButton!
        @IBOutlet weak var RecordBTN: UIButton!
    
        var soundRecorder : AVAudioRecorder!
        var SoundPlayer : AVAudioPlayer!
    
        let fileName = "audioFile.wav"//ここがwavの場合のみエラーがでる。
    
        override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
            setupRecorder()
        }
    
        func setupRecorder(){
    
    
            let recordSettings = [AVSampleRateKey : NSNumber(float: Float(8000.0)),
                AVFormatIDKey : NSNumber(int: Int32(kAudioFormatAppleLossless)),
                AVNumberOfChannelsKey : NSNumber(int: 2),
                AVEncoderAudioQualityKey : NSNumber(int: Int32(AVAudioQuality.Max.rawValue))];
    
            var error: NSError?
    
            do {
                //  soundRecorder = try AVAudioRecorder(URL: getFileURL(), settings: recordSettings as [NSObject : AnyObject])
                soundRecorder =  try AVAudioRecorder(URL: getFileURL(), settings: recordSettings)
            } catch let error1 as NSError {
                error = error1
                soundRecorder = nil
            }
    
            if let err = error {
                print("AVAudioRecorder error: \(err.localizedDescription)")
            } else {
                soundRecorder.delegate = self
                soundRecorder.prepareToRecord()
            }
        }
    
        func preparePlayer(){
    
            var error : NSError?
    
            do{
                SoundPlayer = try AVAudioPlayer(contentsOfURL: getFileURL())
            }
            catch let error as NSError{
                //error = error1
                SoundPlayer = nil
            }
    
            if let err = error {
                print("AVAudioPlayer error: \(err.localizedDescription)")
            }

            }
        }

            return paths[0]
        }

            //let path  = getCacheDirectory().stringByAppendingPathComponent(fileName)
            let path  = (getCacheDirectory() as NSString).stringByAppendingPathComponent(fileName)
            let filePath = NSURL(fileURLWithPath: path)
    
            //let filePath = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(filename))
            return filePath
        }
    
        @IBAction func Record(sender: UIButton) {
    
            if sender.titleLabel?.text == "Record"{
    
                soundRecorder.record()
        //ここでEXC_BAD_INSTRUCTION(code=EXC_1386_INVOP,subcode=0x0)というエラーが出てしまいます。
    
                sender.setTitle("Stop", forState: .Normal)
                PlayBTN.enabled = false   
            }

                PlayBTN.enabled = false
            }  
        }
    }

swift
音声録音時のエラーについて
wavファイルで録音したい場合、recordSettingsのAVFormatIDKeyはkAudioFormatLinearPCMじゃないでしょうか？
