Feature or enhancement

Support the "Mac Catalyst" flavour of macOS binaries on recentish version of macOS

Pitch

MacOS currently has two ways to build "native" applications:

1. The macOS binaries used from macOS 10.0, for ease of reference I'll call these "Cocoa"
2. MacCatalyst binaries that link to (a subset) of the frameworks used on iOS, but recompiled for macOS

The latter have access to some interesting system APIs that former cannot use, such as the HomeKit framework. The current builds are "Cocoa" builds.
