Is Reggie dependent upon Swift 4.1?

[ty-n-42]

Hi,
I get an error when trying to build Reggie in macOS Sierra. In automata.swift XCode complains that compactMap isn't a member; line 123: Value of type '[Transition<Input, Meta>]' has no member 'compactMap'.

I think compactMap was introduced in swift 4.1 and the version of XCode that supports swift 4.1 doesn't support macOS Sierra.

Before I go through the grief of upgrading to High Sierra I thought I'd check in with you to see if you also think that is the problem.

Thanks,
Ty

After upgrading I can confirm that compilation works. It does seem like Reggie is now dependant upon Swift 4.1 and, on the Mac at least, Xcode 9.3 and macOS High Sierra.
