Taskmanager not working in ios device

Expo Application Services (EAS)
,

I am using eas developmentClient for development purpose .

    "development": {
      "developmentClient": true,
      "distribution": "internal"
    },

I have define a taskmanager where I get latest user current latlng and send notification based on that.
In android its working fine , but in ios device it is not working .
I have define this also in app.json:

  infoPlist: {
        UIBackgroundModes: [
          "location",
          "fetch",
          "remote-notification",
          "processing",
        ],
}

This is my taskmanager code:

const BACKGROUND_FETCH_TASK = "BG_FETCH_TASK";

TaskManager.defineTask(BACKGROUND_FETCH_TASK, async ({ data, error }) => {
  if (error) {
    console.log("TaskManager encountered an error:", error);
    return;
  }
  try {
    console.log("TaskManager is running >>>>>>>>>>>>>>>>> ");
    const currentLocation = await Location.getLastKnownPositionAsync();
    //perform my other custom tasks to send noticication
    return BackgroundFetch.BackgroundFetchResult.NewData;
  } catch (e) {
    console.error(e);
  }
});

const registerBackgroundFetchAsync = async () => {
    await BackgroundFetch.registerTaskAsync(BACKGROUND_FETCH_TASK, {
      minimumInterval: BACKGROUND_INTERVAL, // Minimum interval in seconds (e.g., 15 minutes)
      stopOnTerminate: false, // Continue background fetch even if the app terminates
      startOnBoot: true, // Start background fetch on device boot
    });
};

const unregisterBackgroundFetchAsync = async () => {
  const isRegistered = await TaskManager.isTaskRegisteredAsync(
    BACKGROUND_FETCH_TASK
  );
  if (isRegistered) {
    await BackgroundFetch.unregisterTaskAsync(BACKGROUND_FETCH_TASK);
    console.log("Background unregistered");
  }
};

Am i missing any other configuration for this taskmanager to work in iphones ?
