My code is here:

    var ti = NSInteger(interval)
    var ms = ti * 1000
    var secon

I think this way is a easier to see where each piece comes from so you can more easily modify it to your needs

extension TimeInterval {
    private var milliseconds: Int {
        return Int((truncatingRemainder(dividingBy: 1)) * 1000)
    } 

    private var seconds: Int {
        return Int(self) % 60
    } 

    private var minutes: Int {
        return (Int(self) / 60 ) % 60
    } 

    private var hours: Int {
        return Int(self) / 3600
    } 

    var stringTime: String {
        if hours != 0 {
            return "\(hours)h \(minutes)m \(seconds)s"
        } else if minutes != 0 {
            return "\(minutes)m \(seconds)s"
        } else if milliseconds != 0 {
            return "\(seconds)s \(milliseconds)ms"
        } else {
            return "\(seconds)s"
        }
    }
}
