# KeyframeAnimator

A container that animates its content with keyframes.

## Declaration

```swift
nonisolated struct KeyframeAnimator<Value, KeyframePath, Content> where Value == KeyframePath.Value, KeyframePath : Keyframes, Content : View
```

## Overview

Overview The content closure updates every frame while animating, so avoid performing any expensive operations directly within content.
