How do I setup a Unit Test for Swift?

Question

I viewed WWDC\'s Objective-C version and pretty much understand the Objective-C paradigm: importing the head

There is a good tut here:

Making sure the class file you want to test has it's target membership checked for Tests in the file Identity inspector in the utilities panel. This caught me the first time.

The solution recommended by Steve Rosenberg is an easy one but leads to issues that are hard to debug (an instance of which is documented here if you're interested).

The recommended approach is to edit your app target's (not the test target) Build Settings and set "Defines Module" under Packaging to YES.

With that done, in your test target, at the top of each .swift file, import your projects main module to get access to your classes, structs, etc. The name of the main module is typically the same name as your Xcode project file.

Note: When following this approach, you will have to annotate all class/struct/enum methods that you want to test with the public access control modifier.
