That's a question that is more appropriate for swift-users.  You want the place where some compiler folks hang out...

Using the REPL to do this would allow you to explore the binding at runtime, as many REPL-based languages afford.  Is that the kind of thing you're after?

As Swift LLDB is implemented on top of LLDB, there are two projects involved with regards to the source.  The source code for the core of LLDB (as available via llvm.org) is available according to the terms of the license as spelled out at llvm.org.  The Swift-specific parts (i.e. any files not in the llvm.org LLDB source base) are available according to the license as specified at swift.org.  I would direct you to those licenses to see if they are compatible with your desired usage.

It is definitely possible to go the route of setting up an app that communicates with LLDB to get a REPL experience that way.
