Is there apple swift version 5.3.3??

I have this error.

Failed to build module 'XCTest' from its module interface; the compiler that produced it, 'Apple Swift version 5.3.3 (swiftlang-1200.2.41.2 clang-1200.0.32.8)', may have used features that aren't supported by this compiler, 'Apple Swift version 5.3.2 (swiftlang-1200.0.45 clang-1200.0.32.28)'

I was making Alarm app, and searched the code from GitHub (https://github.com/natsu1211/Alarm-ios-swift)
please tell me how to solve it.
English isn’t my first language, and It my first code, so please use Plane english.

Thank you.

Mac version : 11.2.3
Xcode version : 12.4
