KIF and Quick/Nimble

I'm trying to get KIF and Quick/Nimble for iOS playing together nicely, so I can use QuickSpecs for my KIF tests.

My test currently looks like this:

class AuthSignUpSpec: QuickSpec {

    override func spec() {
        describe("Home screen") {
            it("should have a failing test") {
                let tester = self.tester()
                tester.waitForViewWithAccessibilityLabel("Blah")
            }
        }
    }
}

The text 'Blah' doesn't exist and the test should fail. failWithException:stopTest: is being called but it isn't raising an exception or causing the QuickSpec test to fail.

How do I integrate these two technologies?
