NSNumber predicate in iOS swift

-

 Problem:

I want to filter NsNumber entries in core data. So i tried to use predicate with %@ but it crashes the app.

How to solve that?

Solution:

                        let datePredicate = NSPredicate(format: "date.integerValue <= %@",selectedDate)

                        let filtered = dataArray.filtered(using: datePredicate)


It will works fine
