Problem combining a date and a time into a single NSDate

Question

I am trying to combine the time value (hours, minutes, seconds) of one NSDate with the date value (day, month, year) of a second NSDate with this m

Answer 1

Here it is in Swift 2

func combineDateAndTime(date: NSDate, time: NSDate) -> NSDate {

    let calendar = NSCalendar.currentCalendar()
    let dateComponents = calendar.components([.Year, .Month, .Day], fromDate: date)
    let timeComponents = calendar.components([.Hour, .Minute, .Second], fromDate: time)

    let components = NSDateComponents()
    components.year = dateComponents.year
    components.month = dateComponents.month
    components.day = dateComponents.day
    components.hour = timeComponents.hour
    components.minute = timeComponents.minute
    components.second = timeComponents.second

    return calendar.dateFromComponents(components)!
}
