# UIFocusDebugger

A runtime object for debugging focus-related interactions.

```
@MainActor class UIFocusDebugger
```

## Overview

You do not use this class or its methods directly from your code. During a debugging session, you can call the methods of this class from the `lldb` debugger command line to obtain information about the current state of the focus system.

## Topics
