As a Framework Author, I should be able to add ObjC Generated Interface Header to my Umbrella Header

Classification: Reproducible:Always
 
Summary:
A framework author cannot import the Objective-C Generated Interface Header (Module/Module-Swift.h) in the umbrella header because it fails on fully cleaned compiles.

This requires framework users to manually import the Swift portion of a Framework's API.

Steps to Reproduce:
1. Clone the Nimble Project (https://github.com/Quick/Nimble)
2. Include Nimble as a dependency to an Objective-C project.
3. Use the Objective-C API as follows:

   - Import Nimble.h
   - Write `expect(@1).to(equal(@1));` in a method body

4. Attempt compile, build should fail because `to` is not defined
5. Edit Nimble.h to add:
  #import <Nimble/Nimble-Swift.h>
6. Recompile (it may pass).
7. Fully clean derived data.
8. Recompile. It fails with no module found or could not find Nimble-Swift.h file.

Expected Results:


Actual Results:


Version:
Xcode 6.3.2
Xcode 7.0 beta (7A120f)

Notes:
More context: https://github.com/Quick/Nimble/issues/129

Nimble defines the result of `expect()` in Swift, which requires the generated header to be imported.

Comments

Apple's recommended workaround is to use @import instead.
