When trying to run Swift Foundation library tests (TestFoundation) from XCode, XCode says that it cannot import SwiftXCTest (No Such Module 'SwiftXCTest').
Note that I am able to build new swift runtime using 2.2 swift so the tools are properly installed, and I am running xcode properly from command line using
xcrun launch-with-toolchain /Library/Developer/Toolchains/swift-latest.xctoolchain
on Xcode 7.2 Beta 4 ; El Capitan
Is there anything else that needs to be done in order to properly run tests?
Thank you!
