Apple seriously needs to add a macOS Simulator to the Xcode toolset, like, yesterday. You should be able to install macOS runtimes just like every other platform, and build and run apps directly from Xcode to any of them. Doing compatibility testing for macOS is a nightmare compared to iOS

@stroughtonsmith I hope for that (or something docker like for macOS images) every year at WWDC.
We run compatibility testing across Mac and Linux at the @SwiftPackageIndex and have two identical Linux machines running all Linux builds - and three uniquely configured macOS machines for the Apple builds. I.e. redundancy on Linux and three single points of failure on macOS.
Swift versions are so much easier to handle on Linux.
