Hey guys, im just breaking into Core Data and as an example I have an 'Employee' Entity that I have created a .h and .m file for using Xcodes automatically tool. For ex, I want to make one of the attributes of this Entity dependent on two other attributes. Like fullName is a combination of lastName and firstName. How do I edit the .h and .m files to do this? Do I add a getFullName method and have it return the combined string? I'd rather just have the fullName attribute construct itself so I can just retrieve it as needed.
