    Composition is `"has a"` or `"contains a"` relationship.. whereas inheritance is `"is a"` or `"is a type of"` relationship.. Example: A Gorilla has 2 Legs (composition - Gorilla class would have 2 instance of Leg class).. However.. A Gorilla is an Animal (inheritance).. Thus Gorilla would inherit all the properties and traits of an animal. This is not specific to swift. It's for all Object-Oriented languages. – Brandon Jan 21 '18 at 21:54

  • @HazemMohamed Brandon's comment is also very valuable The **Has-a** and **Is-a** are very easy to understand rules. For more see [here](https://en.wikipedia.org/wiki/Has-a) – mfaani Jan 22 '18 at 16:20
