MapMarker onSelect does not fire with Google Maps on iOS

[sameerxanand]

Summary

This implementation deployed in v1.12.0 is not working when using Google Maps on iOS.

Per the JSDoc:

/**
 * Callback that is called when the marker becomes selected.
 * This will be called when the callout for that marker is about to be shown.
 *
 * @platform iOS: Supported.
 * @platform Android: Supported
 */
onSelect?: (event: MarkerSelectEvent) => void;

Reproducible sample code

import MapView, { Marker, PROVIDER_GOOGLE } from "react-native-maps";
import { useState } from "react";

const mapAnnotations = [
  {
    latitude: 40.74063557912163,
    longitude: -73.99162665798178,
    title: "Test",
  },
]

const NEW_YORK_REGION = {
  latitude: 40.733748,
  longitude: -73.960588,
  latitudeDelta: 0.001,
  longitudeDelta: 0.1,
};

export default function App() {
  const [initialRegion, setInitialRegion] = useState(NEW_YORK_REGION);

  return (
    <MapView
      className="w-full h-full"
      provider={PROVIDER_GOOGLE}
      showsUserLocation
      followsUserLocation
      region={initialRegion}
    >
      {mapAnnotations.map((annotation) => (
        <Marker
          key={`${annotation.latitude}, ${annotation.longitude}`}
          coordinate={{
            latitude: annotation.latitude,
            longitude: annotation.longitude,
          }}
          title={annotation.title}
          onSelect={(e) => console.log(e)}
          onDeselect={(e) => console.log(e)}
        />
      ))}
    </MapView>
  )
}

Steps to reproduce

Hi, @sameerxanand are you sure that you have newest version of react-native-maps? Maybe you should try to clean cache
with one of those commands? https://docs.expo.dev/troubleshooting/clear-cache-macos-linux/
When I tried to reproduce this bug for the first time I had the same problem, but building on another simulator fixed it for me so I'm pretty sure that it's something with expo caching :)
