Swift days between two NSDates

Question

I\'m wondering if there is some new and awesome possibility to get the amount of days between two NSDates in Swift / the \"new\" Cocoa?

E.g. like in Ruby I would do:

Answer 1

I see a couple Swift3 answers so I'll add my own:

public static func daysBetween(start: Date, end: Date) -> Int {
   Calendar.current.dateComponents([.day], from: start, to: end).day!
}

The naming feels more Swifty, it's one line, and using the latest dateComponents() method.
