# SKPhysicsJointSpring

A joint that simulates a spring connecting two physics bodies.

## Declaration

```swift
class SKPhysicsJointSpring
```

## Mentioned in

Getting Started with Spring Joints

## Overview

Overview An SKPhysicsJointSpring object simulates connecting two physics bodies together with a spring. The farther the two objects move from each other, the more force is applied to bring the two bodies back together.
