In case anyone is looking for quick one-to-one mapping of Swift version based on Xcode Version:

Xcode 11.6   :      Swift version 5.2.4

Xcode 11.5   :      Swift version 5.2.4

Xcode 11.4   :      Swift version 5.2

Xcode 11.3   :      Swift version 5.1.3

Xcode 11.2.1 :      Swift version 5.1.2

Xcode 11.1   :      Swift version 5.1

Obtained with running following command as mentioned on different Xcode versions:

/Applications/Xcode11.5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift --version
