问题
I made a typo debugging my project and appeared in lldb swift REPL now I don't know how to exit it and simultaneously do not exit from my program which I debug. So I typed expr -r -- myVariable instead of expr -R -- myVariable. and below is what I see. (if you want to try personally I use Xcode 6.1, C++ code project, and myVariable has to exist)
(lldb) expr -r -- record.mFileRecord.mVolumeName
(std::string) $19 = ""

(here my application terminated and lldb was self-killed)
回答1:
With a single colon you can leave the Swift REPL and return to lldb:
(lldb) repl 1> 2> 3> : (lldb)
(Found here: http://swift.exomachina.com/how-to-use-lldb-to-debug-swift-program.)
With :quit
you can stop the entire debugging session:
(lldb) repl 3> 4> 5> :quit 5> Program ended with exit code: 9
