Swift Object-oriented types

1. Class

2. Structure (struct)

3. Enumeration (enum)

Object-oriented through classes and structs in swift language, enumerations have object-oriented features in Swift language

Examples and objects

In object-oriented, the process of creating an object from a class is called instantiation, so the object is called instantiation, but in swift, enumerations and structs cannot be called objects, because structs and enumerations are not completely object-oriented types, but contain only some object-oriented specific, for example, Inheritance occurs only on classes in swift, structs and enumerations cannot inherit
