How do we find out a next day in Swift language? Suppose today is 2014-09-15. How we can find out a date: 2014-09-16.
Swift code without using NSCalendar:
var today = NSDate()
var res = today.dateByAddingTimeInterval(24*60*60)
println("\(today), \(res)") // 2014-09-15 10:31:28 +0000, 2014-09-16 10:31:28 +0000
