I'm attempting to transform a Swift v1.2 project into a Swift v2.0 project via Xcode 7.0.

I got this during the build:

Swift had fatal errors constructing the ast context for this module: missing required module 'SwiftShims' Debug info from this module will be unavailable in the debugger.

What is the module 'SwiftShims'?
And how would I install it if it is missing?

I was getting a similar error message regarding the SwiftShims module, so this is probably only a partial solution to your case.

I had to clean all the user data Xcode was using and empty all caches. This did the job for me:
