Instance MethodSwift

randomElement()

Returns a random element of the collection.

func randomElement() -> Self.Element?

Returns

A random element from the collection. If the collection is empty, the method returns nil.

Overview

Call randomElement() to select a random element from an array or another collection. This example picks a name at random from an array:

let names = ["Zoey", "Chloe", "Amani", "Amaia"]
let randomName = names.randomElement()!
// randomName == "Amani"

This method is equivalent to calling randomElement(using:), passing in the system’s default random generator.
