ObservableObject Starter

Practice the simplest ObservableObject loop.

Create an ObservableObject with one published property.

Repeat by binding it to two views.

Observe how updates propagate.

This drill makes shared state feel stable.

You learn when to lift state up.

Repetition makes the pattern automatic.

Mark the class as @MainActor to keep updates safe.

Test with two views updating the same data.

Try the repetition loop

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