Can you host TVJS files on Apple TV instead of an external server?

Question

I downloaded the TVMLCatalog app from Apple. The code is broken into 2 parts.

• client - this contains TVML and TVJS files
• The TVMLCatalog project is the main Xcode project that installs TVML / TVJS

I am trying to host TVJS client files in the same package as the TVMLCatalog Project .

I modified AppDelegate didFinishLaunching as follows:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    window = UIWindow(frame: UIScreen.mainScreen().bounds)

    /*
    Create the TVApplicationControllerContext for this application
    and set the properties that will be passed to the `App.onLaunch` function
    in JavaScript.
    */
    let appControllerContext = TVApplicationControllerContext()

    /*
    The JavaScript URL is used to create the JavaScript context for your
    TVMLKit application. Although it is possible to separate your JavaScript
    into separate files, to help reduce the launch time of your application
    we recommend creating minified and compressed version of this resource.
    This will allow for the resource to be retrieved and UI presented to
    the user quickly.
    */

    TVBootURL = NSBundle.mainBundle().pathForResource("application", ofType: "js")!
    TVBaseURL = TVBootURL.stringByReplacingOccurrencesOfString("application.js", withString: "")
    if let javaScriptURL = NSURL(string: TVBootURL) {
        appControllerContext.javaScriptApplicationURL = javaScriptURL
    }

    appControllerContext.launchOptions["BASEURL"] = TVBaseURL

    if let launchOptions = launchOptions as? [String: AnyObject] {
        for (kind, value) in launchOptions {
            appControllerContext.launchOptions[kind] = value
        }
    }

    appController = TVApplicationController(context: appControllerContext, window: window, delegate: self)

    return true
}

Here is a screenshot demonstrating how I imported the client : Xcode screenshot

When I run the project (only tested on the simulator), I get the following message displayed on the screen of the AppleTV simulator:

- . ( TVMLKitErrorDomain 3.)

TVJS ?
