如何解释在Firebase中没有完全符号化的崩溃报告？

Question

我们用火力坠毁的分析在我们的应用程序，它帮助我们通过指定函数名，甚至行号也解决的bug快，但有时只给

appDelegate.swift [启动+ 17644]

我该如何诠释这份报告？为什么它看起来像这样？

这是完整的跟踪与线程，应用程序名称是由APPNAME

Answer 1

您的应用程序崩溃，因为异常的替代。由于您的数据不显示异常字符串，因此未知哪种异常会引发崩溃。

由于FBSDKCoreKit框架中的问题（可能是Facebook第三方SDK）引发了异常。由于您很可能未将该框架的调试符号上载到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。

异常是由处理NSDictionary对象的问题触发的，可能试图为某个键插入nil值，但这只是一种猜测。

由于生成的堆栈跟踪中唯一的非系统框架来自您的应用程序调用，因此Firebase通过该调用对崩溃进行了分组，而不是FBSDKCoreKit中的调用。

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。有了这些信息，就不可能知道事故发生的原因以及如何解决这个问题。
