Constants, Variables, and Data Types

  • Waqar Malik

Abstract

In OOP languages, an immutable object is an object whose state can’t be modified. Swift calls these constants. Once a constant object has been created and an initial value has been assigned, the object cannot be changed. In contrast, an object whose value can be changed is a mutable object, or the object can be mutated. Swift calls these objects variables.
