FileManager和urlsForDirectory错误在Swift 3 Xcode 8

Question

我刚刚从测试版3到Xcode 8测试版4，但由于什么原因我得到这个错误，没有错误的工作或发布，直到测试版4.这里是错误“ Value of type 'FileManager' has no member 'urlsForDirectory' “

我的代码：

func setupRecorder(){ 

     let audioSession:AVAudioSession = AVAudioSession.sharedInstance() 

     //ask for permission 
     if (audioSession.responds(to: #selector(AVAudioSession.requestRecordPermission(_:)))) { 
      AVAudioSession.sharedInstance().requestRecordPermission({(granted: Bool)-> Void in 
       if granted { 
        print("Permission Granted\n") 

        //set category and activate recorder session 
        do { 
         //---- 
         let fileManager = FileManager.default 
         let urls = fileManager.urlsForDirectory(.documentDirectory, inDomains: .userDomainMask) 
         //---- 
         let documentDirectory = urls[0] as URL 
         let soundURL = try! documentDirectory.appendingPathComponent("sound.m4a") 

         try audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord) 

         try self.soundRecorder = AVAudioRecorder(url: soundURL, settings: self.recordSettings) 

         let micInput = try AVAudioRecorder(url 
         : soundURL, settings: self.recordSettings) 


         self.soundRecorder.prepareToRecord() 
         self.soundRecorder.updateMeters() 



        } catch { 

         print("Error Recording"); 

        } 

       } 
      }) 
     } 

    } 

但唯一的部分是这一行：

   let urls = fileManager.urlsForDirectory(.documentDirectory, inDomains: .userDomainMask) 

” 'Value of type 'FileManager' has no member 'urlsForDirectory'“

你只需将其更改为网址（:)如下：

let documentDirectory = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first!
