Switching Selector.

## When To Use

- If you need to represent the switching between two states or on-off state.
- The difference between `Switch` and `Checkbox` is that `Switch` will trigger a state change directly when you toggle it, while `Checkbox` is generally used for state marking, which should work in conjunction with submit operation.

## Examples

<!-- prettier-ignore -->
<code src="./demo/basic.tsx">Basic</code>
<code src="./demo/disabled.tsx">Disabled</code>
<code src="./demo/text.tsx">Text & icon</code>
<code src="./demo/size.tsx">Two sizes</code>
<code src="./demo/loading.tsx">Loading</code>
<code src="./demo/component-token.tsx" debug>Custom component token</code>

## FAQ

### Why not work in Form.Item?

Form.Item default bind value to `value` property, but Switch value property is `checked`. You can use `valuePropName` to change bind property.

```tsx | pure
<Form.Item name="fieldA" valuePropName="checked">
  <Switch />
</Form.Item>
```
