Core principle 85% of navigation problems stem from path state management errors, view identity issues, or placement mistakes—not SwiftUI defects.
SwiftUI's navigation system is used by millions of apps and handles complex navigation patterns reliably. If your navigation is failing, not responding, or behaving unexpectedly, the issue is almost always in how you're managing navigation state, not the framework itself.
