# UIUpdateInfo

An object that contains detailed information about the current UI update state.

## Declaration

```swift
@MainActor class UIUpdateInfo
```

## Overview

Overview During a UI update, this object provides details about the state of the update. When using a UIUpdateLink, you can query this UI update information object to learn about the current UI update. A UI update can service views on different displays simultaneously, which means these views can have a different UIUpdateInfo. Get the UI update information for a specific view using current(for:) or a specific window using current(for:). The UI update information can also change as the current UI update progresses through its phases.
