Answer 1

For Swift 3 you can use this function:

//get next date by adding hours func  

getNewDateAfterAddingHours(hoursToAdd:NSInteger, oldDate:Date) -> Int64 {
    let calendar = Calendar.current
    let newDate = calendar.date(byAdding: .hour, value: hoursToAdd, to: oldDate)
    return Int64((newDate?.timeIntervalSince1970)!)
}
