how do you create a button in swift?

To create a button in Swift, you can use SwiftUI, which provides a straightforward way to define and customize buttons. Here are some examples and details from various WWDC sessions:

Basic Button Creation:
- In SwiftUI, a button is created using the Button view. You define the action and the label for the button.
- Example:
```
Button(action: {
    // Action to perform
    print("Button tapped!")
}) {
    Text("Tap me!")
}
```
Customizing Button Appearance:
- You can customize the appearance of a button using various modifiers. For instance, you can change the font, color, and style.
- Example from the session Meet the Contact Access Button:
```
Button(action: {
    // Action to perform
}) {
    Text("Contact Access")
}
.font(.headline)
.foregroundColor(.blue)
```
Using Button Styles:
- SwiftUI provides different button styles such as borderlessButtonStyle, borderedButtonStyle, and custom styles.
- Example from the session Migrate your TVML app to SwiftUI:
```
Button(action: {
    // Action to perform
}) {
    VStack {
        Image(systemName: "star")
        Text("Favorite")
    }
}
.buttonStyle(BorderlessButtonStyle())
```
Adaptive Buttons:
- SwiftUI buttons are adaptive and can change their appearance based on the context they are used in.
- Example from the session SwiftUI essentials:
```
Button(action: {
    // Action to perform
}) {
    Text("Adaptive Button")
}
.buttonStyle(DefaultButtonStyle())
```
