How do I use theming and appearance APIs?

In Swift, theming and appearance APIs allow you to customize the look and feel of your applications easily. You can use them to set default styles for your UI elements across the entire app.

To use these APIs, you typically work with the `UIAppearance` protocol. By conforming to this protocol, you can set global styles for components like buttons, navigation bars, and table views.

For example, if you want to customize the appearance of all buttons throughout your app, you can do so by using the `UIAppearance` APIs in your AppDelegate’s `application(_:didFinishLaunchingWithOptions:)` method.
