How to move to next TextField in SwiftUI?

问题

Using Swift5.1.2, iOS13.2, Xcode-11.2,

Having several TextFields in a Stackview, I would like to move to the next TextField as soon as the user types x-amount of characters into the first TextField.

With this link, I achieve to recognise when a TextField entry has reached x-amount of characters. However, I do not know how to make the firstResponder jump to a second TextField inside my StackView.

Is there a solution to this inside SwiftUI ?
