As a programmer I need to compile for many platforms on X86, on Arm, mac silicon and for many OS systems like Windows, macOS, Linux, Rtos. For this Builds I use mostly Github Actions so I have no more work to do. Especially while working with mac silicon in development I am compiling for all platforms my code and signing my Apple stuff automated.
As it is not possible to use Xojo with github actions but c#, c++ and other languages I wanted to know who else uses it.
Oh, we’re pushing our Xojo Code to GitHub and let GitHub Action Workflows build the Xojo Projects 
Example: GitHub: jo-tools/xojo-github-actions
Obviously not on GitHub hosted Runners… but with a self-hosted Runner installed on a Mac.
At work, all our C# Projects are being built with GitHub Actions.
And here I’ve contributed the Build Actions for another OpenSource x-platform project:
GitHub: Xojo CubeSQLPlugin
We’re building all Targets there (including macOS CodeSigning) and packaging the final Xojo Plugin.
With an own runner for the XoJo stuffs..interesting.
