Set current time to yyyy-MM-dd using swift : the code I've used is working but I have a problem. For example, when the minute is 02, it says 2. I want it to be 02. He writes without 0. Do you help me share the code?

    @objc func tick() {
            var calendar = Calendar(identifier: .iso8601)
            calendar.timeZone = NSTimeZone.local
            let currentDay = calendar.component(.day, from: Date())
            let currentMonth = calendar.component(.month, from: Date())
            let currentYear = calendar.component(.year, from: Date())
            let currentHour = calendar.component(.hour, from: Date())
            let currentHour1 = calendar.component(.minute, from: Date())
    
            labelTimer.text = String (currentDay) + ("/") + String (currentMonth) + ("/") + String (currentYear) + ("/") +  String (currentHour) + (":") + String (currentHour1)
    
        }
