Git commit hash in SwiftUI

One day I’d like to add the Git commit hash to an “about” page in an app.

When that day comes, this post might be hepful.

tl;dr:

Add this to a new Run Script build phase:

GIT=`xcrun -find git`
GIT_REV=`${GIT} rev-parse --short HEAD`
/usr/libexec/PlistBuddy -c "Set :REVISION ${GIT_REV}" "${SRCROOT}/{{path-to-your-info.plist-file}}"

Then in the Swift code:

let revision = Bundle.main.object(forInfoDictionaryKey: "REVISION") as? String 

Of course the key could be eg COMMIT_HASH (or whatever) instead of REVISION, if we wanted.
