Watchman Error, cannot deploy to device

I’ve been looking all day for a solution, and either I’m looking in the wrong places, or this error hasn’t been seen yet.

I’m trying to deploy my app to my iPhone 6 (iOS 9.3) in Release mode. This is my AppDelegate.m:

#import "AppDelegate.h"

#import "RCTRootView.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation;

  /**
   * Loading JavaScript code - uncomment the one you want.
   *
   * OPTION 1
   * Load from development server. Start the server from the repository root:
   *
   * $ npm start
   *
   * To run on device, change `localhost` to the IP address of your computer

   */

  //jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

  /**

   */

  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"◼︎◼︎◼︎◼︎"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
}

@end

It boots up fine in Debug mode, but when I try to bundle it for release, the build fails and I get the following error from watchman:

Versions

• OSX 10.11.4
• Xcode 7.3
• react-native 0.23.1
• node 5.0
• npm 3.3.6
• watchman 4.4.0

I’m not all that familiar with the inner workings of all this, so any help would be greatly appreciated. Thanks for your time!

Hey did you find a solution for this? I’m getting the same problem

Oh, for the record, I’ve tried uninstalling and reinstalling watchman via homebrew, including doing it with the --HEAD parameter, and I still get the same issue.
