我们在我们的应用程序中使用firebase崩溃分析,它帮助我们通过指定函数名称甚至行号来快速解决错误,但有时它只给出

appDelegate.swift [start + 17644]

我该如何解读这份报告？为什么它看起来像那样？

这是带有线程的完整跟踪,应用程序名称由appName替换

解决方法

您的应用因异常而崩溃.由于您的数据未显示异常字符串,因此不知道触发崩溃的异常类型.

由于FBSDKCoreKit框架中存在问题而引发了例外,该框架可能是Facebook第三方SDK.由于您很可能没有将该框架的调试符号上传到Firebase,因此它们无法对它们进行符号化,并提供在这些框架中调用的类和方法.

由处理NSDictionary对象的问题触发异常,可能是尝试为键插入nil值,但这只是猜测.

由于生成的堆栈跟踪中唯一的非系统帧来自您的应用程序调用,Firebase通过该调用而不是FBSDKCoreKit中的调用对崩溃进行分组.

要了解有关这些崩溃的更多信息,您需要上传FBSDKCoreKit框架的符号.根据给定的信息,不可能知道崩溃是什么以及如何解决它.
