Identifiable & Stable IDs
Make models Identifiable for correct diffing.
The Diffing Problem
When data changes, SwiftUI must know which rows moved, stayed, or vanished. Stable identity makes that diffing correct. 🧩
Why id: .self Is Fragile
Using id: .self breaks when two items are equal or a value changes, because the identity shifts unexpectedly.
