How can I choose Swift compiler version

Question

I\'m using Xcode 7.3 but my project is in Swift 2.1. I don\'t want to update my codes right now. So how can I choose or download older version of Swift compiler? Many thanks

Xcode 9 - Xcode 10

Select your target, then in your Build Settings, search for "swift language" and then you will find Swift Language Version.
