Xcode: how to exit lldb swift repl

Question

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> help expr /var/folders/zv/r3033x4n0f72bprvyk8612480000gn/T/lldb/30856 /repl433.swift:2:5: error: consecutive statements on a line must be  separated by ';'  1> quit  /var/folders/zv/r3033x4n0f72bprvyk8612480000gn/T/lldb/30856 /repl434.swift:2:1: error: use of unresolved identifier 'quit'  quit   1> exit  /var/folders/zv/r3033x4n0f72bprvyk8612480000gn/T/lldb/30856/repl435.swift:2:1: error: use of unresolved identifier 'exit'  exit    1> exit()  /var/folders/zv/r3033x4n0f72bprvyk8612480000gn/T/lldb/30856/repl436.swift:2:1: error: use of unresolved identifier 'exit'  exit()  ^   1> quit()  /var/folders/zv/r3033x4n0f72bprvyk8612480000gn/T/lldb/30856/repl437.swift:2:1: error: use of unresolved identifier 'quit'  quit()     1> .quit  /var/folders/zv/r3033x4n0f72bprvyk8612480000gn/T/lldb/30856 /repl438.swift:2:2: error: could not find member 'quit'  .quit  ^~~   1> :quit 

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

Answer 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
