Some common features in Swift structures and Swift classes are as follows :
* Swift Structs and Swift classes can both define attributes for storing values and functions.
* With init, both structures and classes in Swift can create initializers to set up their initial state ()
* They can be extended using extensions.
* They can follow protocols, such as those used in Protocol Oriented Programming.
* They can collaborate with generics to create types that are adaptable and reusable.
