For developers, CarPlay offers a unique opportunity to create innovative and engaging automotive experiences. This comprehensive guide will provide you with a step-by-step tutorial on CarPlay programming, empowering you to develop apps that enhance the driving experience.

Prerequisites
Basic iOS development skills
Xcode 10 or later
iOS device running iOS 12 or later

Creating a CarPlay App1. Start a new Xcode project: Select "CarPlay App" as the project type.
2. Choose a CarPlay interface: Select "Car Interface" or "Template Interface." Car Interface provides more customization options, while Template Interface offers a prebuilt template.
