//first link solution:
extension Date {

    static func -(recent: Date, previous: Date) -> (month: Int?, day: Int?, hour: Int?, minute: Int?, second: Int?) {
        let day = Calendar.current.dateComponents([.day], from: previous, to: recent).day
        let month = Calendar.current.dateComponents([.month], from: previous, to: recent).month
        let hour = Calendar.current.dateComponents([.hour], from: previous, to: recent).hour
        let minute = Calendar.current.dateComponents([.minute], from: previous, to: recent).minute
        let second = Calendar.current.dateComponents([.second], from: previous, to: recent).second

        return (month: month, day: day, hour: hour, minute: minute, second: second)
    }

}

//implimentation in controler
let interval = Date() - updatedDate
print(interval.day)
print(interval.month)
print(interval.hour)
