 To build, download Swift from https://swift.org/download/ -- if you are using macOS, make sure you have the command line tools installed as well).  Test that your compiler works using `swift --version`, which should give you something like
 
 	$ swift --version
-	swift-driver version: 1.75.2 Apple Swift version 5.8 (swiftlang-5.8.0.124.2 clang-1403.0.22.11.100)

 on macOS, or on Linux you should get something like:
 
 	$ swift --version

-The Swift wrappers have been tested with glib-2.56, 2.58, 2.60, 2.62, 2.64, 2.66, 2.68, 2.70, 2.72, 2.74, and 2.74, and gdk/gtk 3.22, 3.24 as well as 4.0, 4.2, 4.4, and 4.6 on the `gtk4` branch.  They should work with higher versions, but YMMV.  Also make sure you have `gobject-introspection` and its `.gir` files installed.
