How do I work with existentials and any keyword in Swift?

In Swift, you can use the `any` keyword to define existentials, which allow you to work with values of various types that conform to a specific protocol. This feature is useful when you want to handle different types uniformly.

Keywords: Swift, Existentials, any keyword
Description: Understanding and utilizing the 'any' keyword in Swift allows for flexible and dynamic programming with protocols and their conforming types.
// Example of using 'any' keyword in Swift protocol Drawable { func draw() } struct Circle: Drawable { func draw() { print("Drawing a circle") } } struct Square: Drawable { func draw() { print("Drawing a square") } } func render(shape: any Drawable) { shape.draw() } let circle = Circle() let square = Square() render(shape: circle) // Output: Drawing a circle render(shape: square) // Output: Drawing a square

Keywords: Swift Existentials any keyword
