Set picker starting with two digit numbers (from 00) - SwiftUI

Question

I have a ForEach inside a picker with numbers from 0 to 20 that shows 0, 1, 2...20 but instead I need to display 00, 01, 02...20. How can I do it?

Do you want your output value to be a `String` to have a `0` in-front, or an `Int` which you can pad zeroes in-front later on? I feel like an `Int` would be more useful. — George, Aug 09 '20 at 23:45
I actually have a string that stores the current data picker — xmetal, Aug 09 '20 at 23:46
I just feel like you would need to check against each `String` value separately, but it's up to you. — George, Aug 09 '20 at 23:47
My current picker shows the output like this: ForEach(0 ..< 21) { item in Text("\(item)")} — xmetal, Aug 09 '20 at 23:50

You use the normal string formatting String(format: "%02d", 5):

@State var num: Int = 0

var body: some View {
   Picker("", selection: $num) {
      ForEach(0..<21) { v in 
         Text(String(format: "%02d", v)) 
      }
   }
}
