Hi Brian,

First of all thanks for the tutorial and this helped me a lot. I do have a quick questions with Core data setup.  
I have cocoapods installed in my project and I added my entities and attributes and when try to create NSManagedObject Subclass, I get all the dialogue boxes, but couldnt see the target to select.  
I tried changing and manually adding it to the target, but I get a crash  
‘An NSManagedObject of class ‘MyUserProfile’ must have a valid NSEntityDescription.’ and couldnt do anything about it.  
I tried the same without cocoapods and it works totally fine. So, can you help me in this please? Thank you.

This is really off the scope of the tutorial. Your best bet is to go to stack overflow and see if someone if running into a similar issue. Thanks!
