@David-Healey I've fixed it - just incase anyone ever sees similar weirdness in future -
Open Terminal and:
xcode-select -pThat should return similar to:
/Applications/Xcode.app/Contents/DeveloperIf not, sort it with this:
sudo xcode-select --switch /Applications/Xcode.app sudo xcodebuild -runFirstLaunchThen reset dev tools:
sudo xcode-select --reset sudo xcodebuild -license acceptDelete derived data and module cache:
rm -rf ~/Library/Developer/Xcode/DerivedData rm -rf ~/Library/Developer/Xcode/ModuleCache.noindexDouble check clang if you've got clang errors:
clang --version xcrun clang --versionIf either of those hang, reinstall clang.
Reinstall commandlinetools:
sudo rm -rf /Library/Developer/CommandLineTools xcode-select --installDelete Xcode caches (bit severe but I think this is what sorted mine out):
rm -rf ~/Library/Caches/com.apple.dt.Xcode rm -rf ~/Library/Preferences/com.apple.dt.Xcode.plistThen reboot, open HISE and try your compile again - mine went straight through, no errors!
