# peerPickerController(_:sessionFor:)

Asks the delegate to return a session for the specified connection type.

## Declaration

```swift
optional func peerPickerController(_ picker: GKPeerPickerController, sessionFor type: GKPeerPickerConnectionType) -> GKSession
```

## Parameters

- `picker`: The controller requesting the session.
- `type`: The type of connection the controller wants to configure.

## Discussion

Discussion Your delegate is responsible for providing a GKSession to use to find and connect to other devices. When the peer picker needs a session, it calls this method. Your application can either create a new session or return a previously created session to the peer picker. The session that your application returns to the peer picker must advertise itself as a peer (GKSessionMode.peer). If your delegate does not implement this method and the user selected a network of type GKPeerPickerConnectionType.nearby, the peer controller allocates a new session that advertises itself as a peer (GKSessionMode.peer) with the default sessionID and displayName parameters. Special Considerations In iOS 3.0, your delegate receives requests only for networks of type GKPeerPickerConnectionType.nearby.
