        .CalendarUnitMinute | .CalendarUnitHour | .CalendarUnitDay |
        .CalendarUnitMonth | .CalendarUnitYear, fromDate: UTCDate,

Here Where I want to give toDate in swift 2.

Answer 1

The options parameter in Swift 2 for this method is not an optional anymore so you can't pass nil to it, you have to pass an empty array if you don't want to specify options:

let components1 = NSCalendar.currentCalendar().components([.Year, .Month, .Day, .Hour, .Minute, .Second], fromDate: UTCDate, toDate: date!, options: [])
