Swift Core Libraries https://www.swift.org/documentation/core-libraries/ • Foundation • https://github.com/apple/swift-corelibs-foundation • libdispatch • https://github.com/apple/swift-corelibs-libdispatch • XCTest • https://github.com/apple/swift-corelibs-xctest

Foundation • Swift.org - The Future of Foundation • Swift.org - Foundation Package Preview Now Available • https://github.com/apple/swift-foundation is the native, unified Swift implementation The Swift code in the package is the core of the Foundation framework that ships on macOS, iOS, and other Apple platforms.

Foundation • swift-corelibs-foundation will be replaced and deprecated someday • At the moment, building/testing swift-corelibs-foundation on macOS with Xcode is broken so very difficult/almost impossible • Contributing to swift-foundation rather than swift-corelibs- foundation is recommended

XCTest and swift-testing • A New Approach to Testing in Swift - Evolution / Discussion - Swift Forums • swift-testing is under active, ongoing development • Contributing to swift-testing rather than swift-corelibs-xctest is recommended
