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

let calendar = NSCalendar.currentCalendar();
let component1 = calendar.component(.Day, fromDate: fromDate)
let component2 = calendar.component(.Day, fromDate: toDate)
let difference  = component1 - component2
