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!
