解析入門套件的斯威夫特3

Question

我已經下載了ParseStarterProject版本1.14.3和下載後，要求我先轉換爲迅速3.之後給我一個錯誤：

Cannot convert value of type '(Bool, NSError?) ->()' to expected argument type 'PFBooleanResultBlock?' 

代碼：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { 
    let installation = PFInstallation.current() 
    installation?.setDeviceTokenFrom(deviceToken) 
    installation?.saveInBackground() 

    PFPush.subscribeToChannel(inBackground: "") { (succeeded: Bool, error: NSError?) in 
     if succeeded { 
      print("ParseStarterProject successfully subscribed to push notifications on the broadcast channel.\n") 
     } else { 
      print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.\n", error) 
     } 
    } as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock 
} 

我試着用另一個線程（AppDelegate.swift function returning errors after converting to swift 3 (cannot convert to PFBooleanResultBlock?)?）

解決，但給我這個錯誤：

"Expected) in the expression list"

我試圖複製相同的錯誤，我只是更換swift3生成代碼：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { 
    let installation = PFInstallation.current() 
    installation?.setDeviceTokenFrom(deviceToken) 
    installation?.saveInBackground() 


    PFPush.subscribeToChannel(inBackground: "") { (succeeded, error) in 
     if succeeded { 
      print("ParseStarterProject successfully subscribed to push notifications on the broadcast channel.\n") 
     } else { 
      print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.\n", error) 
     } 
    } 

} 

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { 
    if error._code == 3010 { 
     print("Push notifications are not supported in the iOS Simulator.\n") 
    } else { 
     print("application:didFailToRegisterForRemoteNotificationsWithError: %@\n", error) 
    } 
}
