SwiftUI navigation interview questions

Navigation is where SwiftUI apps get complex, so interviews use it to test whether you can keep routing state clean and testable.

Modern navigation in SwiftUI

NavigationStack with a value-based path replaced the older NavigationView and NavigationLink-only approach, letting you drive navigation from state. You push values, map them to destinations with navigationDestination, and can manipulate the path programmatically, which makes flows testable and enables restoring or resetting navigation from data.

Deep links and coordinator-like flows

Explain handling a deep link by decoding it into path values and setting the stack's path, so the same routing logic serves both taps and external links. For larger apps, describe a coordinator-like router that owns navigation state, keeping views declarative and decoupled from where a route leads. State restoration falls out naturally when the path is codable.

Frequently asked

What replaced NavigationView?

NavigationStack with a value-based path and navigationDestination, which lets you drive navigation from state and manipulate it programmatically.

How do you handle deep links in SwiftUI?

Decode the link into path values and set the NavigationStack path, reusing the same destination mapping that handles in-app navigation.
