[rok-globtim]

Same. Any updates?

[mRaffaello]

Same for me.
Seems to be caused by the introduction of Kotlin 2.0 from React Native 0.77

[gavrichards]

I asked ChatGPT and it's suggested some changes which could be implemented using patch-package:
https://chatgpt.com/share/6849b782-87c8-8001-8e23-157668179e25

Would anyone else be able to give it a check-over to see if it all seems sensible?

[geroale]

Same issue here

[gavrichards]

We fixed this in our app in two ways.

1. Add this file to the root: react-native.config.js

module.exports = {
  project: {},
  dependencies: {
    // Disable autolinking of react-native-carplay on Android
    // because it contains Kotlin code that is incompatible with RN 0.79
    'react-native-carplay': {
      platforms: {
        android: null,
      },
    },
  },
};

2. Wherever the CarPlay object is referenced in your code, first check the platform is iOS.
   e.g.

if (CarPlay.connected) {

becomes

if (Platform.OS === 'ios' && CarPlay.connected) {

You'll need to import Platform if you're not already:

import {Platform} from 'react-native';

And that does the trick. It's a pain and I'd rather we hadn't had to make these changes, but until the Kotlin code in this package is addressed, it's the simplest way we found.

Still have the same issue here
