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 in advance!

Answer 1

The following example is tested on Xcode 8.3 with swift 3.1

If you are using Xcode 8 you can download toolchains with needed Swift versions

1) Open this link: https://swift.org/download/#releases

2) Download Toolchain with swift version that you need. For example I have 3.1 version of swift and downloaded swift 3.0.2

3) Open .pkg file and install it.

4) Open Xcode and select in menu:

Xcode -> Toolchains -> Select Swift Version you need.

That is all folks
