iOS 12 CarPlay Example

An example of using the CarPlay framework in iOS 12 and later.

Summary

This sample project uses the CarPlay framework to start a simple navigation session from your existing project. It utilizes the CPApplicationDelegate to connect to your car, CPInterfaceController to attach your view controller and CPMapTemplate to show and example template as part of the "root template" of the controller.

Notes

Some general hints I have noticed so far:

CarPlay works primarily in "templates", not "views" or "controllers". It means that you cannot design your CarPlay screen like you would design your iOS app, but you need to provide information that is then displayed in the related template.
The connection is done via the CPApplicationDelegate delegate that inherits from the UIApplicationDelegate, so you usually handle it as part of your main app-delegate class.
Once connected, you can push and pop templates like you would do with view controllers
Data can be used by shared frameworks, networking or general persistence layer. In this example, I simply persist an encoded dictionary of latitude and longitude pairs in the UserDefaults and grab it for my CarPlay connection once ready.

More?

Let me know if you have further questions! As of for now, this is a tiny example to get your head around the whole framework, but it can be extended to show other template types like lists, grids and UI elements like alerts and notifications.
