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

NSTimeInterval is Double do do it with extension. Example:

extension Double {

    var formattedTime: String {

        var formattedTime = "0:00"

        if self > 0 {

            let hours = Int(self / 3600)
            let minutes = Int(truncatingRemainder(dividingBy: 3600) / 60)

            formattedTime = String(hours) + ":" + (minutes < 10 ? "0" + String(minutes) : String(minutes))
        }

        return formattedTime
    }
}
