Variables,Objective-C stores information in variables. These are divided into two types: primitive types and composite types. Primitive variables store one piece of information, such as a number or a character. Composite variables store a set of information, such as three related numbers and a character.

Objects,Objective-C objects are entities that contain both behavior and attributes in one place. Behaviors are coded in methods while attributes are coded in properties. Objects can also include private instance variables. Private instance variables are used when data storage is required, but not needed to be shared.
