Shadowing is when a subclass defines a constant, property or enumeration (almost anything that is not an event or a method) that has the same name as a constant, property or enumeration (but not an event or a method) in the superclass. Generally the best rule is avoid using the same names for constants, properties and enumerations that the superclass has already used.

Comments closedAs you may have heard, Apple announced that as of February 1st, 2015, all new apps submitted to the iOS App Store must support 64-bit. It was already our intention to be in beta testing on 64-bit in that timeframe. However, our original plan was to support Linux first since more and more Linux servers now only support 64-bit.
