Object Functionality

Protocol in Swift allows different objects of different types to have a common set of functionality. It serves as a blueprint that defines a set of properties and methods that can be adopted by structs and classes. To define a protocol in Swift, use the following syntax: protocol Mammal { } Structs and classes can adopt a protocol by indicating it after the colon: struct Dog: Mammal { } class Cat: Mammal { } A protocol can define properties and methods but does not provide values or implementations....
