what are biggest navifation problems with navigationlink in swift

Some of the biggest navigation problems with NavigationLink in SwiftUI are:

1. Unwanted navigation: Sometimes NavigationLink can lead to unwanted navigation, where clicking on a link navigates the user to a screen they did not intend to go to.

2. Lack of customization: NavigationLink does not offer a great deal of customization options. For example, it is not possible to change the font color of the link or add any animations.

3. Difficulty nesting views: It can be challenging to nest views that use NavigationLink because the navigation hierarchy is global, and modifying it requires navigating back to the root view.

4. No back button control: NavigationLink automatically generates a back button for each view when navigating, but it lacks the ability to customize or disable it entirely.

To mitigate these problems, it is often advisable to use other navigation solutions such as NavigationButton and customize it as per requirements.
