Xcode 4.2 requires first letter as lowercase for Core Data Attributes

Question

Does anyone know why Xcode 4.2 is requiring an attribute name to start with a lowercase letter in core data model? Will there be any issue going forward?

Answer 1

It has always been this way because Objective-C standard naming conventions recommend a lower case first letter for iVars, properties, etc. Core Data is just enforcing that recommendation.
