# run(_:completion:)

Adds an action to the list of actions executed by the node and schedules the argument block to be run upon completion of the action.

```
func run(_ action: SKAction, completion block: @escaping () -> Void)
```

## Parameters

`action`

The action to perform.

`block`

A completion block called when the action completes.

## Discussion

> Important:
> You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration:
> 
> ```swift
> func run(_ action: SKAction) async
> ```
> 
> For information about concurrency and asynchronous code in Swift, see <doc://com.apple.documentation/documentation/Swift/calling-objective-c-apis-asynchronously>.
