If, like me, you couldn't wait for less rounded corners and installed the MacOS beta on your only Mac, you might realize that you can't push updates to the app store. In this situation I would recommend the 25 free Xcode cloud hours that you get with the program membership. All I had to do was put my code in Git and connect the repo. Then I set it to archive for app store.

This might be the easiest CI/CD system I've ever used and the builds are pretty fast! Hats off to the Xcode cloud team.
