iOS: background-fatch not working

[Rutvik-tbz]

I'm working on background fetch for the local notification function with time intervals of 15 minutes, but this is not working. function does not work after 15-20 minutes.

Your Environment

• Platform: iOS
• React Native version (react-native -v): 0.74.1
• React-native-background-fetch: "^4.2.5",

AppDelegate.m

#import "AppDelegate.h"

#import <UserNotifications/UserNotifications.h>
#import <RNCPushNotificationIOS.h>

#import <Firebase.h>

#import <React/RCTBundleURLProvider.h>
#import <TSBackgroundFetch/TSBackgroundFetch.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  self.moduleName = @"Disaster Counter Measures";
  // You can add your custom initial props in the dictionary below.
  // They will be passed down to the ViewController used by React Native.
  self.initialProps = @{};

  // Define UNUserNotificationCenter
  [[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];
  UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  

  // [REQUIRED] Register BackgroundFetch
  [[TSBackgroundFetch sharedInstance] didFinishLaunching];

  if ([FIRApp defaultApp] == nil) {
    [FIRApp configure];
  }
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

code

// index.js 
const configureBackgroundFetch = () => {
	BackgroundFetch.configure(
		{
			minimumFetchInterval: 15,
			stopOnTerminate: false,
			startOnBoot: true,
			requiredNetworkType: BackgroundFetch.NETWORK_TYPE_ANY,
			requiresCharging: false,
			requiresDeviceIdle: false,
			requiresBatteryNotLow: false,
			requiresStorageNotLow: false,
		},
		async (taskId) => {
			console.log('[BackgroundFetch] Event received: ', taskId);
			showlocalNotification() //it will show local notification 
			BackgroundFetch.finish(taskId);
		},
		(error) => {
			console.error('[BackgroundFetch] failed to start: ', error);
			handleError({
				error,
				screen_name: 'Index',
				function_name: 'configureBackgroundFetch',
			});
		},
	);
};

// Call configureBackgroundFetch on app load
configureBackgroundFetch();

In my project, I have also set up for https://github.com/transistorsoft/react-native-background-geolocation,

And if I log states of react-native-background-fetch configuration, then it gives me status code 2
