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.
