# MagnifyGesture

A gesture that recognizes a magnification motion and tracks the amount of magnification.

## Declaration

```swift
nonisolated struct MagnifyGesture
```

## Overview

Overview A magnify gesture tracks how a magnification event sequence changes. To recognize a magnify gesture on a view, create and configure the gesture, and then add it to the view using the gesture(_:including:) modifier. Add a magnify gesture to a Circle that changes its size while the user performs the gesture: struct MagnifyGestureView: View {     @GestureState private var magnifyBy = 1.0

var magnification: some Gesture {         MagnifyGesture()             .updating($magnifyBy) { value, gestureState, transaction in                 gestureState = value.magnification             }     }

var body: some View {         Circle()             .frame(width: 100, height: 100)             .scaleEffect(magnifyBy)             .gesture(magnification)     } }
