# connectionTypesMask

A mask that determines the types of connections a dialog presents to the user.

## Declaration

```swift
var connectionTypesMask: GKPeerPickerConnectionType { get set }
```

## Discussion

Discussion Your application configures the connection types it allows before showing the peer picker. If your application allows more than one connection type, the peer picker offers the user a choice of which type of connection to use. The default value for the mask is GKPeerPickerConnectionType.nearby. important: In iOS 3.0, GKPeerPickerConnectionType.nearby is required to be one of the allowed connection types. An exception is thrown if your application does not include it.
