I am getting a message in my debugger:

The LLDB RPC server has crashed. The crash log is located in ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log.

In my case the LLDB RPC server consistently crashed every time I ran my app, even after cleaning the build folder and removing and reinstalling Xcode (Version 8.3.3 (8E3004b)) completely.

It turned out that apparently LLDB took objection to a breakpoint I had set, just moving this breakpoint by a line resolved the issue.
