Variables are essentially locations in computer memory reserved for storing the data used by an application. Each variable is given a name by the programmer and assigned a value. The name assigned to the variable may then be used in the Swift code to access the value assigned to that variable. This access can involve either reading the value of the variable or changing the value. It is, of course, the ability to change the value of variables which gives them the name variable.
