# easeInOut

An animation that combines the behaviors of in and out easing animations.

## Declaration

```swift
static var easeInOut: Animation { get }
```

## Return Value

Return Value An ease-in ease-out animation with the default duration.

## Discussion

Discussion An easing animation provides motion with a natural feel by varying the acceleration and deceleration of the animation, which matches how things tend to move in reality. An ease in and out animation starts slowly, increasing its speed towards the halfway point, and finally decreasing the speed towards the end of the animation. The easeInOut animation has a default duration of 0.35 seconds. To specify the duration, use the easeInOut(duration:) method. The following code shows an example of animating the size changes of a Circle using an ease in and out animation. struct ContentView: View {     @State private var scale = 0.5

var body: some View {         VStack {             Circle()                 .scale(scale)                 .animation(.easeInOut, value: scale)             HStack {                 Button("+") { scale += 0.1 }                 Button("-") { scale -= 0.1 }             }         }     } }
