LLDB throwing auto import error in Swift Xcode pro

问题:

I'm trying to use the debugger in Xcode to poke around in one of my methods. The app is pretty bare bones, just one example class at this point. When I set a breakpoint and run, the LLDB debugger pane opens in Xcode as expected. However, if I try to execute a print command to poke around in my method, I get the following error:

Error in auto-import:

I get the same error if I enter the repl and execute a command.

Hemal from Crashlytics here! We reached out to Apple on the behavior that everyone is seeing and they confirmed it's a bug in LLDB around Swift. We don't have an firm timeline yet as to when it will be fixed, but the bug report that it's being tracked in is 18256812.
