Xcode: how to exit lldb swift repl

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 = ""

1> :quit


(here my application terminated and lldb was self-killed)

With a single colon you can leave the Swift REPL and return to lldb:

<pre>
(lldb) repl
1>
2>
3> :
(lldb)
</pre>
(Found here:

.)

With `:quit` you can stop the entire debugging session:
<pre>
(lldb) repl
3>
4>
5> :quit
5> Program ended with exit code: 9
</pre>
