When I build and run swift through Xcode, the terminal duplicates my
input. For example,
var x = 3
vvar ar x x = =3 3
When I run the same swift binary through Terminal.app, that doesn't
happen. I also tried a basic test project that reads stdin and it
doesn't have that behavior.
Does anyone have any ideas on how to get the Xcode terminal to behave
properly with the swift repl?
