# CPApplicationDelegate

The interface for handling CarPlay life-cycle events.

```
protocol CPApplicationDelegate : UIApplicationDelegate
```

## Overview

You must implement [`CPApplicationDelegate`](/documentation/CarPlay/CPApplicationDelegate) on the same object that serves as the delegate to your app.

## Topics

### Connecting to the CarPlay Interface

[`application(_:didConnectCarInterfaceController:to:)`](/documentation/CarPlay/CPApplicationDelegate/application(_:didConnectCarInterfaceController:to:))

Tells the app delegate that the app connected to the CarPlay interface.

[`application(_:didDisconnectCarInterfaceController:from:)`](/documentation/CarPlay/CPApplicationDelegate/application(_:didDisconnectCarInterfaceController:from:))

Tells the app delegate that the app disconnected from the CarPlay interface.

### Receiving the Selected Maneuver

[`application(_:didSelect:)`](/documentation/CarPlay/CPApplicationDelegate/application(_:didSelect:)-6ybyy)

Tells the app delegate that the user selected a maneuver.

### Handling Navigation Alert Actions

[`application(_:didSelect:)`](/documentation/CarPlay/CPApplicationDelegate/application(_:didSelect:)-478jb)
