分段錯誤11修復？

我試圖做一個應用程序，你在一定數量的時間點按下按鈕儘可能多次。我一直在構建它，並在過去的一週左右每天在我的iPhone上運行它，但是現在突然間Xcode正在給我提供錯誤和「錯誤分段11」。我刪除了添加的代碼，從故事板中刪除了某些內容，甚至重新安裝了Xcode，但沒有任何方法可以解決問題。有關於如何解決這些問題的文章和視頻，但他們中沒有一個似乎對我有用。分段錯誤11修復？

這裏是我的代碼：

import UIKit 
import Foundation 
import AudioToolbox 


// PlaySounds 
class PlaySounds { 

    private var soundID: SystemSoundID = 0 

    public init(named name: String) { 
     if let soundURL = soundURL(forName: name) { 
      let status = AudioServicesCreateSystemSoundID(soundURL as CFURL, &soundID) 
      if status != noErr { 
       print("Unable to create sound at URL: '\(name)'") 
       soundID = 0 
      } 
     } 
    } 

    public func play() { 
     if soundID != 0 { 
      AudioServicesPlaySystemSound(soundID) 
     } 
    } 

    private func soundURL(forName name: String) -> URL? { 

     let fileExtensions = ["m4a", "wav", "mp3", "aac", "adts", "aif", "aiff", "aifc", "caf", "mp4"] 

     for fileExtention in fileExtensions { 
      if let soundURL = Bundle.main.url(forResource: name, withExtension: fileExtention) { 
       return soundURL 
      } 
     } 
     print("Unable to find sound file with name '\(name)'") 
     return nil 
    } 

    deinit { 
     if soundID != 0 { 
      AudioServicesDisposeSystemSoundID(soundID) 
     } 
    } 
} 

// ViewController 
class ViewController: UIViewController { 

    let startTimer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(UIMenuController.update), userInfo: nil, repeats: true) 

    let XDSound = PlaySounds(named: "XDDDDDDD") 

    @IBAction func playButtonPressed(_ sender: AnyObject) { 

     XDSound.play() 

    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 
    } 


    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 

}

它說的錯誤「（SWIFT）：56：40」的底部，我認爲指的第40個字符第56行，但所有這些都是ViewController的左括號。幫幫我？

我把你的代碼粘貼到Xcode 8的遊樂場中，並立即得到這個錯誤：「LLDB RPC服務器崩潰了。崩潰日誌位於〜/ Library/Logs/DiagnosticReports中，並有一個前綴'lldb-roc-server'。請提交一個錯誤並附上最新的崩潰日誌。「因此，看起來你發現了一個LLDB調試器的錯誤！ –

初始化定時器的行會導致錯誤。

您無法在類的頂層調用目標/操作方法。

要麼變量聲明爲隱式展開的可選

var startTimer : Timer!

和viewDidLoad

override func viewDidLoad() { 
     super.viewDidLoad() 
     startTimer = Timer.scheduledTimer(timeInterval: 0.4, 
               target: self, 
              selector: #selector(UIMenuController.update), 
              userInfo: nil, 
              repeats: true) 
    }

初始化或與閉合變量聲明爲lazy

lazy var startTimer : Timer = { 
    return Timer.scheduledTimer(timeInterval: 4.0, target: self, selector: #selector(update), userInfo: nil, repeats: false) 
}()

並調用它啓動計時器

let _ = startTimer

我再次將他的代碼輸入到操場中，並沒有崩潰。編譯器沒有抱怨定時器或任何東西其他的很奇怪 –

謝謝！我在那裏有一個計時器，但它沒有工作，所以我刪除了它......認爲我擺脫了所有的代碼，我需要睜開眼睛！ –
