How do I bring up the Swift terminal window after entering the Xcode Beta welcome window?
Swift Terminal Window in Xcode Beta
There are a couple of things that you could be referring to:
If you have a swift app, cmd-shift-Y is the default keybinding to open the Console where the output of "print()" will go.
If you pause in the debugger, LLDB understand swift code. From there, you can type "repl" to get an interactive swift session:
(lldb) repl

Just typing "xcrun swift" from Terminal.app will give you the same thing. It will still be lldb, but it will jump directly into repl mode for you to play around with Swift.
Is that what you had in mind?
