Focus change in TextField and SecureField
Reading time: 2 min
Detecting if a text field gained or lost focus is not entirely straightforward in SwiftUI.
TextField constructor has a parameter named onEditingChanged, but it triggers only when the user taps the return key in the virtual keyboard, not when the focus is actually lost.
Even worse, SecureField doesn't have such a parameter, and there's no way to know if the user is interacting with the view!
