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:

Working, you need to set the time to be the same for both days, if you are off by seconds it will be wrong

func daysBetween(start: Date, end: Date) -> Int {
    let start = Calendar.current.date(bySettingHour: 0, minute: 0, second: 0, of: start)!
    let end = Calendar.current.date(bySettingHour: 0, minute: 0, second: 0, of: end)!
    return Calendar.current.dateComponents([.day], from: start, to: end).day ?? 0
}
