//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)
