What is Protocol in swift?

Question

Accepted Answer

Protocols in Swift define a blueprint of methods, properties, and other requirements that a class, struct, or enum must adopt.

Protocols are used to define a set of rules or capabilities that a type must conform to.
They allow for code reuse and provide a way to define common behavior across different types.
A type can adopt multiple protocols, enabling it to conform to multiple sets of rules.
Protocols can require properties, methods, initializers, and associated types.
They can be used for delegation, defining APIs, and creating generic constraints.
Example: protocol Printable { func print() }
Example: class MyClass: Printable { func print() { print("Hello") } }
