With Xcode 7, and @testable, you should no longer need to update the managedObjectClassName or use other hacks. Here's what I did to get it working in Xcode 7.2.

1. Set your test target Host Application and check "Allow testing Host Applications APIs".

2. Make sure none of your regular classes have a Target Membership pointing to the Test target. Only classes with unit test code should be set to the Test target.

3. Add the @testable line to the top of all of your test classes:

import XCTest
@testable import MyApp

class MyAppTests: XCTestCase {
}
