CarPlay developer

Native CarPlay inside Apple's templates, as part of your iOS app.

Specification

STACK
Swift, SwiftUI and UIKit. The CarPlay screens live in the same iOS app, not in a separate project.
CATEGORIES
Audio, navigation and EV: the app types Apple allows on CarPlay.
OPEN SOURCE
Contributions to TDS-Carplay on GitHub, 273 stars.
EXPERIENCE
Native iOS since 2015, including the NOS app and the transit app for HTM, RET, GVB and Connexxion.

CarPlay is not an iPhone app on a bigger screen. Apple hands you fixed templates, a short list of allowed app categories and a review that checks driver distraction. Know it up front and you build once. Find out afterwards and you build twice.

How does your app get into the car?

Your app is audio, navigation or EV
PickCarPlay screen inside the existing iOS app UsuallyThis is the usual answer.
WhyApple allows these categories. App and car screen then share the same code, data and login.
Your app falls outside those categories
PickDo not build it yet
WhyOutside the allowed categories you do not pass review. Better said up front than afterwards.
You want custom UI on the car screen
PickWork with the templates
WhyCarPlay gives lists, grids and Now Playing. Free-form UI does not exist there and stalls in review.
The iOS app is Flutter or React Native
PickAdd the CarPlay layer natively in Swift
WhyThe CarPlay layer talks straight to Apple's frameworks. You write it natively, next to the existing app.
You have an iOS team but no CarPlay knowledge
PickI build only the CarPlay layer
WhyThat layer is small and separate. I work inside your team without taking the app over.
