I have a set of Swift and Objective-C files that extend some of the functionality in the XCTest framework.
I was easily able to create a Cocoa framework composed of these files. I added all the files to an OS X framework target and, since some of them import XCTest headers, I linked XCTest.framework to my framework. Users are able to add the framework to their unit test targets, provided they are building for OS X.
Question: How can I do the same (i.e.: distribute this code) for users building for the iOS simulator?
What I've Tried (1): Cocoa Touch framework
I can't make a Cocoa Touch framework that imports XCTest.framework--doing so results in the following linker error ("Quick" is the name of the framework):

What I've Tried (2): Cocoa Touch static library
Other projects similar to mine that extend the XCTest framework use static libraries to distribute their code. However, attempting to build a static library that includes Swift code results in the following error:

More Information
For those that are interested, or if you need more details, the project in question is on GitHub. I'm keeping track of what I've tried so far using this issue.
How can I distribute this Swift/Objective-C code (which uses XCTest code) to users who wish to use it in their iOS unit tests?
