Xcode中。无法在断点处停下来

标签： ios xcode debugging breakpoints

我在调试iOS应用程序时遇到问题。当应用程序到达断点时，它会停在那里一秒钟然后调试器崩溃。 （应用程序不会崩溃，只有调试器。类似于设备在调试模式下与电缆断开连接的行为）。

来自Xcode控制台的打印：

  

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并具有前缀   ＆＃39; LLDB-RPC服务器＆＃39 ;.请提交错误并附上最近的崩溃   日志中。

我检查了崩溃日志，这是文件的一部分：
