SwiftUI FocusState: A Little Pitfall I Fall Into

Explores a common SwiftUI gotcha where FocusState only updates to true when the bound TextField is already visible on screen. The author demonstrates the problem through a practical example of trying to conditionally show a TextField based on its focus state, which creates a catch-22 situation. The solution involves using a separate State variable to control TextField visibility, synchronized with FocusState through onChange modifiers.
