Swift 2.0: Could not cast value MyApp.MyCustomClass to MyAppTests.MyCustomClass when using Set
I have found a solution:
I suppose that those who has such problem, imported their files into test target this way:
Since they should do it just like this:
So, just remove the files from your test target. And then if you need your files within test target just use @testable keyword within your every test class.
This way there is no problem with casting values between targets anymore. It worked for me:-) Enjoy:-)
