State and Binding Handshake

See how data flows when you repeat @State to @Binding patterns.

Build a parent view with @State and pass a binding to a child.

Repeat with two different inputs: toggle and text field.

Watch the updates travel both ways and note the timing.

This drill makes data flow feel predictable.

Once internalized, your components become reusable.

Repetition removes the fear of stale state.

Repeat the drill with optional bindings to learn edge cases.

Add a unit testable view model to separate state logic.

Try the repetition loop

Pick a SwiftUI concept and write it 50 times. Feel the pattern lock in.
