Question 1

How to pass data between view controllers with Router?

Accepted Answer

Router uses Swift enum cases with associated values to pass data, as shown in the profile example where a Person object is passed to ProfileViewController. This ensures type safety and avoids runtime errors common with string-based routing.

Question 2

Router or Coordinator pattern: which should I use?

Accepted Answer

The authors now favor native Coordinators, as stated in the README. Router provides a library-based solution with enum safety, while Coordinators are a pattern without external dependencies; choose based on project size and preference for third-party libraries.

Question 3

How to test navigation flows using Router?

Accepted Answer

By mocking the AppNavigation object in unit tests, you can verify navigation logic without creating actual view controllers. This centralized approach makes it easier to isolate and test navigation paths, as mentioned in the benefits.

Question 4

Does Router work with deep linking in iOS apps?

Accepted Answer

The README doesn't explicitly cover deep linking, but since Router centralizes navigation, it could be extended to handle deep links by mapping URLs to enum cases. However, you'd need to implement custom parsing logic yourself.

Question 5

Is Router compatible with SwiftUI?

Accepted Answer

No, Router is designed for UIKit and does not support SwiftUI out of the box. For SwiftUI projects, you should look into native navigation tools like NavigationStack or third-party SwiftUI routing libraries.

Question 6

What are good alternatives to Router now that it's deprecated?

Accepted Answer

The authors recommend using native Flow Controllers or Coordinators, as linked in the README. Other options include modern routing libraries like SwiftUI Router for SwiftUI apps or building custom solutions with Combine and state management.
