import AST errors

Getting error that AST cannot be used as it was compiled for 5.3 while Xcode 12 is using 5.3.2

Hi @tgunr

The project was building against Xcode 12.1. I've updated the libraries to work with Xcode 12.2 now. Pull in master to see the changes 👍

@seanhenry looks like this needs another update for Xcode 12.5 / Swift 5.4.
