The xcodeproj gem can't parse PediFoods.xcodeproj's .pbxproj (newer
Xcode format than any released gem version supports), so the runtime
override always fails with a misleading "very old project file" error.
Signing config for the app target needs to live in the checked-in
project settings instead (set once via Xcode's GUI), since no
command-line override can be scoped to a single target without also
breaking the SPM package's own ephemeral targets.
