How to use ButtonStyle

To use ButtonStyle in SwiftUI, you can customize the appearance and behavior of buttons by creating a custom style. Here's a brief overview based on the content from WWDC:

1. Custom Button Styles: You can define a custom button style by conforming to the ButtonStyle protocol. This allows you to control how the button looks and behaves. For example, you can use the hover effect modifier to add effects like scaling or highlighting when the button is interacted with.

2. Using Built-in Styles: SwiftUI provides several built-in button styles, such as borderlessButtonStyle and cardButtonStyle. These styles can be applied to buttons to achieve different visual effects. For instance, the cardButtonStyle provides a rounded platter that subtly lifts and moves, which is useful for creating lockups similar to those in the TV app's search results.

3. Accessibility Considerations: When creating custom button styles, it's important to consider accessibility. Use the styling system over creating a custom view whenever possible to automatically get accessibility properties. You can also use accessibility modifiers to customize how a view is represented by an accessibility element.
