# UIHostingController

A UIKit view controller that manages a SwiftUI view hierarchy.

## Declaration

```swift
@MainActor @preconcurrency class UIHostingController<Content> where Content : View
```

## Overview

Overview Create a UIHostingController object when you want to integrate SwiftUI views into a UIKit view hierarchy. At creation time, specify the SwiftUI view you want to use as the root view for this view controller; you can change that view later using the rootView property. Use the hosting controller like you would any other view controller, by presenting it or embedding it as a child view controller in your interface.
