Swift Version Incompatible
I downloaded the starter files but my new version of XCode is incompatible with swift version 3.
Go to Vending Machine project –> Build Settings -> Basic –> Swift Compiler language and change from Swift 3 to Swift 4

You may also have to select the app from TARGETS and change to Swift 5 etc
