Demo is loading infinitely on iOS

[amsdamsgram]

Hi,

I tried the demo on a iOS simulator and it is loading infinitely.
I tried to log what happens:

I've installed the lib + the dependencies.
I had to installed babel-preset-es2015 too otherwise I was getting an error.
Any inputs on this?

Thanks!

Can you try running npm prepare and then gulp copy?
