Error when packaging for IOS after updating to 4.6

Hey,
I am currently making a game using UE4 for IOS , on my PC.
Everything was working properly, i was using UE 4.5.1, and so i updated the Engine to 4.6 and since then every time i try to package my game, it fails and gives me an error.
I have all of my certificates and profiles running,(there’s a green check next to each one).
Is there something new in the engine i need to update?
Thanks.

I have tried changing from Distribution to shipping, optimising the game for mobile devices but nothing works.
