That's because you've never fulfilled your expectation (with expectation.fulfill() method). Use XCTWaiter if you don't care about expectation fulfilment.

    expectation(for predicate:...) doesn't require .fulfill to be called - it's a special-case expectation which evaluates itself repeatedly when waitForExpectations is called, based on the outcome of the predicate. – Oletha Jul 04 '18 at 18:14

Is it not just that you need to make your expectation evaluate to true?

let exists = NSPredicate(format: "exists == true")

or 

let exists = NSPredicate(format: "exists == 1")
