Description

I have run the app from xcode & see everything fine; but when I try to run directly from the device, I only see the grey screen. Sometimes the app immediately collapses to the background.
When I run it is xcode, everything appears fine.

Steps to Reproduce

1. run sample in xcode -> ipad device
2. stop app & try running directly from device

I also ensured that my podfile uses this line:
pod "Mapzen-ios-sdk", :git => 'https://github.com/mapzen/ios.git', :branch => 'master', :submodules => true
