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

Swift 3 extension:

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

    let calendar = NSCalendar.current

    let dateComponents = calendar.dateComponents([.year, .month, .day], from: date)
    let timeComponents = calendar.dateComponents([.hour, .minute, .second], from: time)

    var components = DateComponents()
    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.date(from: components)!
}
