No Picture is displayed

[daniapp]

Hello,
I have the problem, that eighter a taken picture nor a load picture from the library is displayed in the app. The Xcode Error is:
2016-03-05 21:13:24.519 Photos Gallery App[783:179898] Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.

Second is that I am on iPhone 6. I upscaled your Storyboard NC and VC's to 4.7 inch. But on the phone it is displayed in 3.7 inch, I think. How can I fix this?
Thanks a lot!
