# GKSessionDelegate

An object implements the GKSessionDelegate protocol to control the behavior of a GKSession object. The delegate is called when other visible peers change their state relative to the session. It is also called to determine whether another peer is allowed to connect to the session.

## Declaration

```swift
protocol GKSessionDelegate : NSObjectProtocol
```
