Question

我通过Crashlytics在我们的应用程序的发布版本中崩溃，我无法在我的任何设备或模拟器上复制。

我对Crashlytics的理解是，崩溃并非来自某些特定的致命错误，而是来自封闭本身的某个地方。当调用完成处理程序时，它似乎发生在第1537行，但我看不出原因。我的语法来自闭包，@escaping的错误使用，或者解包变量，还是使用主线程来完成处理程序（因为它位于Alamofire完成处理程序中？）。

遇到崩溃的用户正在运行与我相同的iOS（11）并且我已通过她的帐户登录并且自己没有问题。

func getObjectsInBackground(completion:@escaping (_ error:AMDError?,_ objects:[Dictionary<String, Any>]?)->()){

    Alamofire.request(URL(string: urlstring)!, method: .get).responseJSON { (response:DataResponse<Any>) in

        switch response.result {

        case .success:


            let results = response.result.value as! NSArray

            var objects = [Dictionary<String,Any>]()

            for result in results {
                let object = result as! Dictionary<String,Any>
                objects.append(object)
            }

            DispatchQueue.main.async {     //<<Line 1537
                completion(nil, objects )
            }


        case .failure(let error):

            let error = AMDError(code: "400", errorString: error.localizedDescription, info: nil)

            DispatchQueue.main.async {
                completion(error, nil)
            }


        } 
    }
}
