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

Here is the answer for Swift 3 (tested for IOS 10 Beta)

func daysBetweenDates(startDate: Date, endDate: Date) -> Int
{
    let calendar = Calendar.current
    let components = calendar.components([.day], from: startDate, to: endDate, options: [])
    return components.day!
}

Then you can call it like this

let pickedDate: Date = sender.date
let NumOfDays: Int = daysBetweenDates(startDate: pickedDate, endDate: Date())
    print("Num of Days: \(NumOfDays)")
