# UITextLoupeSession

An object that manages the presentation of the system magnifier at the location you specify.

## Declaration

```swift
@MainActor class UITextLoupeSession
```

## Mentioned in

Adopting system selection UI in custom text views

## Overview

Overview A UITextLoupeSession object programmatically displays the system loupe in your view. You might display this view to allow someone to magnify your view’s content. Typically, you display the loupe from a UIPanGestureRecognizer when someone interacts with your view. As the location in the gesture recognizer changes, use the loupe session object to update the position of the loupe.
