Support other platforms

[slashmo]

install-swift only supports running on Ubuntu (18.04 & 20.04). Supporting other runner os's like macOS and Windows would make the action more useful.

Platforms to support

• Support macOS #5
• Support Ubuntu 16.04 #8
• Support CentOS 7/8 #9
• Support Windows #10

amazonlinux2 and centos7/8 would be good as well

Thank you, that's a great suggestion! How would you run your CI on GitHub Actions using these distributions? Using the Swift Docker images? In that case, what would be the benefit of installing a specific version of Swift inside the image, if you could have selected this version as part of the image tag already?

I guess you are right there. Forgot GH actions only have Ubuntu runners. I guess if someone has their own runner they can have whatever version of Linux installed on it. Maybe the action should at least recognise this, and download the correct version of swift

Good point, then let's try and support all platforms where both Swift and the GitHub runner tool runs on.
