iOS 应用程序在发布模式下崩溃但在调试中不崩溃（使用 MongoDB 和 Stitch SDK）

Question

我正在使用 MongoDB 和 Stitch SDK（StitchSDK 版本 6.4.0）。 我的 iPhone 应用程序在调试模式下运行，但当我将其构建为发行版并通过 TestFlight 安装时，它崩溃了。 我尝试更改构建设置中的优化级别，但没有成功。

设备日志中涉及崩溃线程的部分如下：

我希望有人能帮助我！

我做了一个解决方法，将所有内容作为文本 (json stringify) 发送到 function，然后在 function 中将其转换回 json。它并不完美，但它可以工作。 如果有人想这样做，这里有一些代码，我也升级到 realm，但原理保持不变：

        // the part in the IOS app 
        
        let app = App(id: "yourapp");
        
        app.login(credentials: Credentials.anonymous) {
            (result) in
            DispatchQueue.main.async{
                switch result{
                case .failure(let error):
                    print("login failed: \(error)")
                case .success(let user):
                    print("Login as \(user) succeeded !")

                    var arrayPlog = [Logj]();
                    //let encoder = BSONEncoder()  // does not work
                    
                    // logs
                    let jsonObjectLog: [String : Any] = [
                        "logs": self.parseLogs(&arrayPlog)
                    ]
                    let jsonData = try? JSONSerialization.data(withJSONObject: jsonObjectLog, options: [])
                    let jsonString = String(data: jsonData!, encoding: String.Encoding.utf8)
                    
                    // user
                    let jsonObjectUser: [String : Any] = [
                        "user": self.getUserInfo()
                    ]
                    let jsonDataUser = try? JSONSerialization.data(withJSONObject: jsonObjectUser, options: [])
                    let jsonStringUser = String(data: jsonDataUser!, encoding: String.Encoding.utf8)
  
                    // call realm function
                    user.functions.AddData([AnyBSON(jsonString!),AnyBSON(jsonStringUser!)]){ Adddata, error in
                        guard error == nil else {
                            print("error")
                            return
                        }
                        print ("function called")
                    }
                    
                    
                }
            }
        }

        ]
      
        return jsonObject

// the AddData function in mongoDB
