@State vs @Binding

Choose the right ownership for each property.

Two Wrappers, One Goal

Both @State and @Binding manage mutable data, but they play different roles. Picking the right one keeps ownership clear. 🎯

@State Owns

Use @State when this view is the source of truth. It creates and stores the value for itself.

@State private var count = 0
