How to set NSPredicate to look for fields different than nil?

I'm trying to fetch fields in CloudKit that are different than nil and, also, that has a specific phone number (at the same time, obviously). But I'm having a hard time trying to do so... That is my code:

let predicate = Predicate(format: "phone == %@ && careTakerId != %@", tel, "")

If exists, it prints a "User exists" and it's printing it every damn time! Can anyone tell me if I'm doing the predicate right? Thank you


Got it by doing the following:

let predicate = Predicate(format: "phone == %@ && careTakerId != ''", tel)

If you try with != nil Xcode will crash and say it's not a valid predicate!
