Actual Behavior

log show nothing when i run xcode with iPhone connected

Steps to Reproduce

  1. run xcode
  2. press || and paste the command
    e -l objc -- (void)[[BGTaskScheduler sharedScheduler] _simulateLaunchForTaskWithIdentifier:@"com.transistorsoft.fetch"]
  3. Click the [ > ] button to continue. --> code did not go to BackgroundFetch.configure. it stop at "BF try,app.tsx" log

#########
code in App.tsx which is imported to index.js

    const initBackgroundFetch = async () => {
      console.log('Initialising background fetch now, app.tsx');    // can see this log
      try {
        console.log('BF try, app.tsx');                                                 //  can see this log
        const status = await BackgroundFetch.configure(               // did not execute this code and onwards
          {
            minimumFetchInterval: 15,
            requiredNetworkType: BackgroundFetch.NETWORK_TYPE_NONE, // Run regardless of network type
          },
          async (taskId: string) => {
            console.log('[BackgroundFetch] task: ', taskId);       // never log out this
           //  background task =>  call location api
           BackgroundFetch.finish(taskId);
          },
          async (taskId: string) => {
            console.error('[BackgroundFetch] TIMEOUT task: ', taskId);   // never log out this
            BackgroundFetch.finish(taskId);
          },
        );
        console.log("bg fetch status = ", status)
  
        if (status === BackgroundFetch.STATUS_RESTRICTED) {
          console.error('[BackgroundFetch] configure failed: STATUS_RESTRICTED');
        } else if (status === BackgroundFetch.STATUS_DENIED) {
          console.error('[BackgroundFetch] configure failed: STATUS_DENIED');
        } else if (status === BackgroundFetch.STATUS_AVAILABLE) {
          console.log('[BackgroundFetch] configure status is STATUS_AVAILABLE');
        }
      } catch (e) {
        console.error('[BackgroundFetch] configure failed: ', e);
      }

Create a fresh new Hello World app, configure the plugin and attempt to reproduce.
