How should a Swift + Objective-C project be setup

Question

I'm finding it very hard to find out how to configure test targets in Xcode 6b4. Can someone point me in the right direction given this scenario.

I have a mostly Swift project. However, there are some 3rd party Objective-C dependencies, which get put into the application's bridging header. I want to write tests for my Swift code. Ideally, in Swift. The problem I have is this....

1. If I create a Swift test case, then the compiler complains that it can't find the Objective-C headers in the application's bridging header.

2. If I create an Objective-C test case, then I cannot import the Swift classes which I want to test.

The only thing which I can do is write Objective-C tests cases, which don't touch any Swift. I cannot write "purely Swift code/tests" due to the Objective-C dependencies.

Does anyone have any advice or had success on this. Or is this the current state of things in Beta 4?

Try putting the #import "xyz-Swift.h" statements into your precompiled header files. That way you have different import statements for all of your Obj-C headers, depending on the target:

MyProject-Prefix.pch (app target):

#import "MyProject-Swift.h"

MyProjectTests-Prefix.pch (test target):

#import "MyProjectTests-Swift.h"
