Error while adding in git after updating to new OS Mojave
Error
git: error: unable to read SDK settings for \'/Library/Developer/CommandLine
Since I had just updated Xcode (using the AppStore) I had to open Xcode and let the installer finish some configuration work before Visual Studio for Mac would successfully compile my Android application again.
I thought this was weird because my solution did not include any projects targeting iOS. The solution contained just a few .NET Core library projects and an Android APK.
I also had to run the 'xcode-select --install' command.
CommandLineTools is outdated. The below should fix it.
xcode-select --install
