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

appDelegate.swift [开始 + 17644]

我该如何解释这份报告？为什么会这样？

这是带有线程的完整跟踪，应用名称替换为appName

您的应用因异常而崩溃。由于您的数据没有显示异常字符串，因此不知道是哪种异常触发了崩溃。

由于FBSDKCoreKit框架中的问题引发了异常，这可能是 Facebook 3rd 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。

异常是由处理NSDictionary对象的问题触发的，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，因此 Firebase 按该调用而不是FBSDKCoreKit.

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。有了给定的信息，就不可能知道崩溃是关于什么以及如何修复它。
