在didRegisterForRemoteNotification中执行自定义操作时崩溃

Question

发生的崩溃是：-

Crashed: com.apple.main-thread
EXC_BREAKPOINT 0x00000001004c6514

以下是崩溃的堆栈竞赛：-

发生崩溃的代码是：-

 static func putJSONRequestWithBody(url: String, targetViewController: UIViewController?, handler: @escaping RiderRideRestClient.responseJSONCompletionHandler,body : Dictionary<String, String>){
    AppDelegate.getAppDelegate().log.debug("")
    var authHeader = [String: String]()
    if SharedPreferenceHelper.getJWTAuthenticationToken() != nil{
        authHeader[Authorization] = SharedPreferenceHelper.getJWTAuthenticationToken()!
    }
}

这是应用程序委托didRegisterForremoteNotification的代码，上面的代码部分在内部调用：-

   func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    AppDelegate.getAppDelegate().log.debug("")
  let deviceTokenString = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    AppDelegate.getAppDelegate().log.debug("\(deviceTokenString)")
    userDefaults.setValue(deviceTokenString, forKey: "deviceTokenString")
    let phone = QRSessionManager.getInstance()?.getUserId()
    if phone != nil && (phone!.count) > 1 && deviceTokenString != nil && !deviceTokenString.isEmpty{

        DeviceRegistrationHelper(sourceViewController: nil, phone: phone!, deviceToken: deviceTokenString).registerDeviceTokenWithQRServer()
    }
}
