Writing tests for swift classes with XCTest written in Objective c

Question

I'm facing a problem trying to write a test for class written in Objective-c and gets injected with a class written in Swift.

Example in the Test file:

SomeSwiftClass *swiftVar = [SomeSwiftClass new];
SomeObjectiveCClass *objVar = [[SomeObjectiveCClass alloc] initWithSwiftClass:swiftVar]

But the complier doesn't recognize the Swift class, and it doesnt support importing the "Target-Swift.h" too..

How can I write a test for both Objective c and Swift at the same TestFile ?

There are quite a few things that need to be in place if you want to use a Swift class in Objective-C.

The bridging header is required "Target-Bridging-Header.h"
Precede the class definition with @objc in the .swift file.
If you're still stuck, try deleting your .swift files and adding them to the project again, and Xcode will ask to generate the bridging header for you.
Check out the documentation: https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html#//apple_ref/doc/uid/TP40014216-CH10-ID138
Or this link: Swift to Objective-C header not created in Xcode 6

I managed to get it working, so if you post more of your code or share what you're doing I might be able to help.
