Swift - Integer conversion to Hours/Minutes/Seconds

Question

I have a (somewhat?) basic question regarding time conversions in Swift.

I have an integer that I would like converted into Hours / Minutes / Second

Answer 1

In Swift 5:

    var i = 9897

    func timeString(time: TimeInterval) -> String {
        let hour = Int(time) / 3600
        let minute = Int(time) / 60 % 60
        let second = Int(time) % 60

        // return formated string
        return String(format: "%02i:%02i:%02i", hour, minute, second)
    }

To call function

    timeString(time: TimeInterval(i))

Will return 02:44:57
