how should i use a Button in bottombar that has icon and text? i tried with .labelStyle(.titleAndIcon) but don't seem to work

To use a button in a bottom bar with both an icon and text in SwiftUI, you should ensure that you are using the correct approach to combine these elements. The .labelStyle(.titleAndIcon) modifier should work, but if it doesn't seem to be working as expected, you might want to check the following:

1. Ensure Correct Usage: Make sure you are applying the .labelStyle(.titleAndIcon) modifier to a Label view, which is designed to combine text and an icon.

2. Use a Label: The Label view is specifically designed to display an icon and text together. Here's a basic example:

   Label("Button Text", systemImage: "star")
       .labelStyle(.titleAndIcon)
   

3. Check for Compatibility: Ensure that your SwiftUI version supports the .titleAndIcon label style. This style should be available in recent versions of SwiftUI.

4. Custom Implementation: If the default label style doesn't work, you can manually create a button with an HStack to combine an Image and Text:

   Button(action: {
       // Your action here
   }) {
       HStack {
           Image(systemName: "star")
           Text("Button Text")
       }
   }
   

If you are implementing a custom tab bar or bottom bar, ensure that you are following the guidelines for custom views as mentioned in the session Get started with Dynamic Type (11:58). This session discusses the importance of maintaining focus on the app's content and how to handle custom bars effectively.
