# interpolatingSpring(_:initialVelocity:)

An interpolating spring animation that uses a damped spring model to produce values in the range of one to zero.

## Declaration

```swift
static func interpolatingSpring(_ spring: Spring, initialVelocity: Double = 0.0) -> Animation
```

## Discussion

Discussion These vales are used to interpolate within the [from, to] range of the animated property. Preserves velocity across overlapping animations by adding the effects of each animation.
