Can someone help me with xCode?

[Blue145]

So I'm beginning to develop my first iPhone app and need a bit of help.

The first is if I have a Standalone app I've built using storyboard and such, is there a simple way to combine that with a game my friend has built using a Cocos2D template? As in say on one of my View Controllers had a button, could I simply make it so when that button is pressed it loads the game?

Also, I've come across an error which I need help fixing, any advice would be really appreciated, thanks.


Here is the error I get:

Not sure about that error without seeing the code that caused it. Should be fairly straightforward to find. Search your code for NSPersistentStoreCoordinator. Maybe you're doing an [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:] without passing in a valid managed object model.
