崩潰NSProxy doesNotRecognizeSelector：

Question

面料讓我發現，很多用戶在我的應用程序

crash http://i65.tinypic.com/30uqnvn.png

下列崩潰。如果我展開我看到下面的堆棧

我假設是有什麼東西不能與WatchKit一起使用。在我的應用程序中，有一類已準備好將數據傳輸到手錶套件應用程序，但在構建階段的這一時刻，沒有提及手錶應用程序和手錶套件擴展。

在我班上的代碼是

import Foundation 
import WatchConnectivity 

class WatchManager: NSObject 
{ 
    func setLanguage(localization: String) 
    { 
     if #available(iOS 9.0, *) { 
      if WCSession.isSupported() { 
       let watchSession = WCSession.defaultSession() 
       watchSession.delegate = self 
       watchSession.activateSession() 
       if watchSession.paired && watchSession.watchAppInstalled { 
        watchSession.transferUserInfo(["localization": localization]) 
       } 
      } 
     } 
    } 
} 

extension WatchManager: WCSessionDelegate 
{ 
    @available(iOS 9.3, *) 
    func session(session: WCSession, activationDidCompleteWithState activationState: WCSessionActivationState, error: NSError?) 
    { } 

    @available(iOS 9.0, *) 
    func sessionDidBecomeInactive(session: WCSession) 
    { } 

    @available(iOS 9.0, *) 
    func sessionDidDeactivate(session: WCSession) 
    { } 
} 

有什麼建議？

它看起來像你的應用程序使用NSProxy子類作爲WCSession的代表。是這樣嗎？如果是這樣，請嘗試將其更改爲NSObject子類。
