Failed to load launch URL with error: Domain Error = TVMLKitErrorDomain Code = 3 "(null)"

Question

Description:

I created a new TVML project and started it. The first error was application transport security, which I installed with Info.plist:

App Transport Security Settings -> Allow Arbitrary Loads -> YES

Then I ran it again and I get this error:

Failed to load start URL with error: (null) appController (_: didFailWithError :) is called with error: Error Domain = TVMLKitErrorDomain Code = 3 "(null)"

The project seems to stop here ( application funcin AppDelegate.swift):

   appControllerContext.launchOptions["BASEURL"] = AppDelegate.tvBaseURL
   print(launchOptions) //returns nil
   //error on following line
   if let launchOptions = launchOptions as? [String: AnyObject] {
        //does not enter here
        for (kind, value) in launchOptions {
            appControllerContext.launchOptions[kind] = value
        }
    }

What I tried:

I tried changing tvBaseURL to " http: // localhost: 9001 / " withhttp://MY-IP-ADDRESS-HERE:9001/

but that didn’t change anything.

Question:

What causes this error and how to solve it?
