I tried running a production version (Scheme -> Build Configuration = Release), the main bundle loads and attempts to start the worker, but this just repeats in my logs:

2016-08-03 13:50:35.543 FutureApp[9291:273962] starting Worker file:///Users/sean/Library/Developer/CoreSimulator/Devices/EC847FD2-23EB-4CAA-B10A-87D8F21F55D7/data/Containers/Bundle/Application/A0442033-AC22-4336-9364-1B2F628ADA6F/FutureApp.app/main.jsbundle

......

I added the worker.js file to my project folder and can confirm it's being copied to the same folder. But it looks like the worker is trying to load the wrong file? The main.jsbundle file is the output of the react native packager, right?

    So, my Objective-C skills are nonexistent, but it seems to work if I hardcode the path to the worker bundle:

    Steps to get it working:

    1. Build an offline bundle of the worker file:
      react-native bundle --platform ios --dev false --entry-file worker.js --bundle-output iOS/worker.jsbundle
    2. Add the worker.jsbundle file to the XCode project. (In the Project Navigator click on the app name, then right click and select Add Files to ...)
    3. In WorkerManager.m change the *workerURL line to point to the file:
      NSURL *workerURL = [[NSBundle mainBundle] URLForResource:@"worker" withExtension:@"jsbundle"];

    Having the same issue in android

    D/WorkerManager( 7970): Starting web worker - src/workers/printers/worker
D/WorkerManager( 7970): createReleaseBundleLoader - reading file from assets
E/        ( 7970): Unable to load script from assets: workers/src_workers_printers_worker.bundle
W/System.err( 7970): java.lang.RuntimeException: Could not connect to development server.

    Listing the assets I can't see the workers asset

    A possible way to overcome this is to create the workers manually

    react-native bundle --entry-file ./src/workers/printers/worker.js --platform android --bundle-output android/app/src/main/assets/workers/src_workers_printers_worker.bundle

    yes it is on the todo list. but basically it is just a matter of calling the RN packager and writing the worker bundle file at the correct location.

    Anyone else seeing issues with RN 0.35?

    I have a src/worker.js and in my code I'm doing: new Worker('src/worker');.

    For the android bundle I'm running:

    react-native bundle \
  --dev false\
  --entry-file ./src/worker.js\
  --platform android\
  --bundle-output android/app/src/main/assets/workers/src_worker.bundle \
  --sourcemap-output android/app/src/main/assets/workers/src_worker.map \
  --assets-dest android/app/src/main/res/

    I'm having the same issue. WorkerManager.m looks like this:

    NSURL *workerURL = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:name fallbackResource:nil];

    How do I find out where I am supposed to write bundle for iOS?
