Bumping Info.plist versions by hand can be very error prone (e.g. remembering to bump multiple targets in a project)
Fortunately Xcode’s cli has an easy solution
xcrun agvtool new-marketing-version <versString>
So if my Application targets are at version 2.0.4 and I need them to be at 2.0.5 I simply run this command at the terminal:
xcrun agvtool new-marketing-version 2.0.5
