relates to:

  • SR-4259 Request: fixit for import module casing

Issue Description:

On a case-insensitive filesystem, if you make an app in Xcode named, say, "foundation", then import Foundation will give you a pretty lousy error message after the first build: "error: cannot load module 'foundation' as 'Foundation'". This is because Xcode provides an explicit search path to the build directory, and will generate a module for the app or framework target (foundation.swiftmodule).

Ideally, we would keep searching to see if there really is a module with the proper case, but I'm not exactly sure how to do that.
