Restrict user to particular time interval

Try This: It will restrict user to select date greater than one month from current date.

let datePicker = UIDatePicker()
let secondsInMonth: NSTimeInterval = 30 * 24 * 60 * 60
datePicker.maximumDate = NSDate(timeInterval: secondsInMonth, sinceDate: NSDate())
