I am working on taking over a development project which I have discovered was created in xcode 8.2.1.
CreatedOnToolsVersion = 8.2.1;
I'd like to be able to build it in xcode 8, but it won't run on Mojave. The solution seems to be to install High Sierra in a virtual machien and build it there, and then move it forward to a newer version of Xcode/Swift.
However, I cannot download High Sierra from any of the app store links I have found, presumably because it was never installed on my new mac to being with, and System Preferences won't download the installer.
Is there a method for me to download this OSX image?
