Basics of OOP(Object Oriented Programming) - You hide all ivars / properties to outside world.

@property is specific to Objective-C, which creates ivars and you are given an option either to use compiler defined setter & getter, or create your own by @synthesize.

Few differences still valid for Objective-C and other OOP languages like ivars/properties are private/protected/public. There are ways to set its access-specifiers.

If you are fancied about ivars and properties one of the major advantage is of KVO (Key Value Observer) this helps you to minimize your codes and only self.property name suffice.
