应用程序崩溃NSDate消息发送到解除分配的实例？

Question

当我启动我的应用时，它会崩溃并且我收到此错误：

启用Zombies对象后，我在日志中收到此错误：

  

- [__ NSDate dealloc]：发送到解除分配的实例0x16765ce0的消息

更新：

我使用了Profile（Cmd + I），我用xcode选择了NSZombie，我得到了这个：

我用户fliclib的代码是：

import UIKit
import GoogleMaps
import FBSDKLoginKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        FlicAuth.sharedInstance
        return true
    }
}

和

import Foundation
import CoreBluetooth

class FlicAuth: NSObject, SCLFlicManagerDelegate, SCLFlicButtonDelegate {
    static let sharedInstance = FlicAuth()
    var flicButton: SCLFlicButton!
    var flicButtons = [SCLFlicButton]()
    var flicError: Int!

    override init() {
        super.init()

        SCLFlicManager.configureWithDelegate(self, defaultButtonDelegate: self, appID: FlicAppId, appSecret: FlicAppSecret, backgroundExecution: false)

    }

    func requestButton(){
        SCLFlicManager.sharedManager()?.grabFlicFromFlicAppWithCallbackUrlScheme("grabButton")
    }

    func flicManager(manager: SCLFlicManager, didGrabFlicButton button: SCLFlicButton?, withError error: NSError?) {
        if (error != nil) {
            print("Error: \(error!.domain) - \(error!.code)")
            return
        }

        button?.delegate = self
        button?.triggerBehavior = .ClickAndDoubleClickAndHold
        button?.connect()
        flicButtons.append(button!)
    }
}

知道为什么我会遇到nsdate问题吗？
