SwiftUI State and Binding: Avoid Two Owners
Two views each hold a copy of the same editable value and drift apart. This guide gives you a small, testable way to approach the issue before changing a live system.
A practical workflow
- Keep a single source of truth and pass a binding to the child that edits it.
- Test navigation back, view recreation and a delayed network update.
What to check
State wrappers differ by ownership and lifetime; choose them for the data flow, not syntax alone. Compare the result with the original problem and record what changed. If a measurement or test does not support the change, revisit the assumption rather than adding more complexity.
Keep the experiment small enough to reverse. Document the starting state, the change and the result so another person can repeat the process. Product menus and versions can change, so check the current documentation for your environment.
