# startSync()

Begins multipeer synchronization.

## Declaration

```swift
func startSync()
```

## Discussion

Discussion Call this method to restart multipeer syncing with connected peers after calling stopSync(). You don’t need to call this method to begin syncing. RealityKit calls this method automatically when you assign a MultipeerConnectivityService to a Scene.
