iOS Firebase可检测事件中的崩溃，但无法识别Crashlytics部分中的应用程序

我花了一整天的时间弄清楚Crashlytics和我的应用程序到底发生了什么。 当我崩溃应用程序时，它会检测到致命事件，但不会激活应用程序的crashlytics部分

它没有检测到应用程序，但它确实检测到崩溃事件：

以下是日志：

当我在那里设置断点时，在调试器中我看到一个字符串，但一旦该字符串传递给FIRCLSEncodeString函数，它就变成了nil

不知道是什么引起的

有什么想法吗？

我找到了原因。 我的应用程序在目标设置中没有显示名称和字符串版本，它导致Crashlytics打印

预期的可编码字符串，但却发现NSNull

，最终没有发送报告。

---

为了调试它，我必须禁用所有优化。

感谢@igor kogan，在我的例子中，构建版本是空的

Expected encodable string, but found NSNull instead. Set a symbolic breakpoint at FIRCLSEncodeString to debug.
