Question

我在Xcode 10.1中有一个包含Objective C和Swift代码的项目。每当我在swift代码中应用断点时，LLDB崩溃，最终结束了调试会话。由于无法调试我，我完全陷入了这种情况代码。我曾尝试将断点移到其他行（由其他一些帖子建议），但它不起作用。有什么解决方法吗？

来自调试器的消息：LLDB RPC服务器已崩溃。崩溃日志位于〜/ Library / Logs / DiagnosticReports中，并带有前缀“ lldb-rpc-server”。

崩溃摘要：

Complete crash log

崩溃正在快速代码中发生，Objective C代码运行正常。同样，它不是偶然的，它每次都在发生。我还尝试清除所有Xcode缓存和派生数据。

Answer 1

我遇到同样的情况，希望我的解决方案对您有所帮助。添加断点时Xcode LLDB崩溃的原因是我的项目名称（<p id="result"></p>）与Apple的框架相同。
将项目名称切换为另一个随机名称后，问题解决了。

每当添加断点时，LLDB就会崩溃
