Property declared in category 'Private' Build Error

Updated Xcode to 4.2 and migrated my project. EGOGradientView is throwing this error on build now: "Property declared in category 'Private' cannot be implemented in class implementation"

in EGOGradientView.m for:
@dynamic layer;

I fixed this by just removing PRIVATE from the interface declaration.
