IOS application works on the simulator but not on the device

Question

I made a simple sign up application with parse backend. Everything works fine. I have no warnings or error code and I can also see the user in the parse dashboard when i create it. But the application only works at the simulator. When I put it on the device, it starts the application but shows a black screen. I tried with an another sample project, just to make sure that my code signing is valid and the other app works on device just fine. So i checked the console logs but I did not understand a whole lot. So could someone be able to help me with this? Thank you.

Here is the console log

Answer 1

Here's one thing I noticed, I won't pretend to know a lot about this, but here's what I got:

I believe this code says that you're missing of Info.Plist keys, all the red text is the keys that your a missing. Below that is trying to send a bug report to apple.

This line seems to me that you have too many files open. I wouldn't know how to fix it, but it might give you something to search.
