typealias UIButtonPointerStyleProvider = (UIButton, __UIPointerEffect, __UIPointerShape) -> UIPointerStyle?
```

## Parameters

- `button`: The button requesting the pointer style.
- `proposedEffect`: The content effect that the system suggests.
- `proposedShape`: The shape of the pointer that the system suggests.

## Return Value

Return Value The pointer style to apply to the button when the pointer hovers over it. Return nil when you don’t want to apply a pointer style to the button.

## Discussion
