whats the best way to navigation in swiftui, is it using hosting uikit navigationcontroller still better?

When it comes to navigation in SwiftUI, it is generally recommended to use SwiftUI's own navigation components rather than relying on UIKit's UINavigationController. SwiftUI provides a declarative approach to building user interfaces, which can be more efficient and easier to manage, especially when dealing with complex navigation hierarchies.

SwiftUI offers various navigation views and tools, such as NavigationView and NavigationStack, which are designed to work seamlessly within the SwiftUI framework. These components allow you to define navigation paths declaratively, making it easier to manage state and transitions.

However, if you have existing UIKit components or need to integrate specific UIKit features, you can still use UIViewControllerRepresentable to wrap UIKit views and controllers within SwiftUI. This interoperability allows you to incrementally adopt SwiftUI in your existing apps or use UIKit components where necessary.

For more detailed information on SwiftUI's capabilities and its interoperability with UIKit, you can refer to the SwiftUI essentials session, which covers SDK interoperability and how SwiftUI can work alongside other frameworks.
