How to migrate to swoft ui navigation?

To migrate to SwiftUI navigation, you can follow these steps based on the content presented at WWDC:

Adopt SwiftUI Navigation APIs: If you are currently using a tab bar, you can easily switch to a sidebar by setting the tabViewStyle to sidebarAdaptable. This will transform your tab bar into a sidebar with all its associated behaviors. This is particularly useful for tvOS and iPadOS, where users can switch between tab bar and sidebar representations.
```
TabView {
    // Your tab views here
}
.tabViewStyle(SidebarAdaptableTabViewStyle())
```
Use NavigationSplitView: For more complex navigation structures, consider using NavigationSplitView. This API allows you to create a split view with a sidebar and a detail view, which is ideal for apps with hierarchical navigation.
```
NavigationSplitView {
    // Sidebar content
} detail: {
    // Detail content
}
```
Integrate SwiftUI with UIKit: If your app is a mix of UIKit and SwiftUI, you can now animate UIKit views using SwiftUI animations. This makes it easier to create fluid, gesture-driven animations and maintain a consistent look and feel across your app.
```
UIView.animate(withDuration: 0.3) {
    // UIKit view animations
}
.animation(.spring())
```
Explore New Transitions: iOS 18 introduces new transitions like the zoom transition, which can be used for both navigation and presentations. This transition is continuously interactive, allowing for a more dynamic user experience.
```
.transition(.zoom)
```
