Can't pass Date to NSPredicate(format: …) without “as CVarArg”

Question

Is this how I\'m supposed to pass a Date to NSPredicate.init(format predicateFormat: String, arguments argList: CVaListPointer).

Answer 1

The %@ format expect a Foundation object as argument, compare "Predicate Format String Syntax" in the "Predicate Programming Guide".

Therefore you have to cast the overlay type Date back to its Foundation counterpart NSDate:

let endDate = Date()
let pred = NSPredicate(format: "endDate == %@", endDate as NSDate)
