In new projects, in the iOS part is necessary to adjust a few parameters, such as signing, and that you can only do in Xcode.

So, try to open the iOS project with Xcode and try to build it from there. You'll see better warning and error messages there, specially regarding signing.

You can open Xcode and locate your project ios folder, or:

cd yourproject/ios
open -a Xcode . 

Then select Product > Run in the menu.
