I am trying to update the swift compiler language version to 5.1. But I am having the latest xcode version of Version 11.3.1 (11C504) Toolchain: Swift 5.1 Snapshot 2020-01-28 (a).
I downloaded the swift-5.1-DEVELOPMENT-SNAPSHOT-2020-01-28-a-osx package and installed but the is added in the toolchain. I couldn't see the required version in the compiler section.
So how to update that.
I have added the screen shot for more details
