How do I know which version of Swift I'm using?

Question

I just created a new Swift project in Xcode. I am wondering which version of Swift is using.

How can I see, in Xcode or terminal, which version of Swift I use in my project?

Answer 1

In the project build settings, there is a "Swift Compiler - Languages" block, which stores information about the Swift language version in key-value format. It will show you the entire available (supported) version of the Swift language for your Xcode and the active version also with a checkmark.

► ( ) ► ► ( 'swift_version' ) Swift ► Swift ► , ( ).

Just by entering the swift command in the terminal, it will show the version and enter the Swift console. (Something like below)

System-IOSs-MacBook-Air:~ system$ swift
Welcome to Apple Swift version 5.1 (swiftlang-1100.0.270.13 clang-1100.0.33.7).
Type :help for assistance.
