# register(_:)

Registers a listener for a particular event.

## Declaration

```swift

```

## Parameters

- `listener`: The object that GameKit sends messages to when events occur.

## Discussion

Discussion Only register a listener a single time. Registering a listener multiple times results in undefined behavior.
