title: Firebase storage download trouble in iOS device (Unity)
body: <p>I met unknown trouble trying to setup firebase storage for iOS. I can't download even 1 file in device, but it runs perfectly in Editor. 
  I am using <code>reference.GetFileAsync()</code> method. Firstly I assumed that I made some wrong package setup or some other silly mistake, but I checked it many-many times. Each Quickstart project <a href="https://github.com/firebase/quickstart-unity/blob/master/storage/testapp/Assets/TestApp/UIHandler.cs" rel="nofollow noreferrer">here</a> works well on my end. My current project settings and firebase storage settings are identical to provided test examples I run in iOS device successfully. </p>
  
  <p>Here is a xCode output trying to download the file. That is looped and contains only that info: <a href="https://codeshare.io/5gL9wY" rel="nofollow noreferrer">codeshare</a> 
  Any of logs googling doesn't give me any solution or even idea.</p>
  
  <p>Please, give me some thoughts where to search the problem.. I am totally confused.
  I am using MacOSx, Unity 5.5.0/5.5.1, latest Firebase Unity SDK (v1.1.2) </p>
