# init(arrayLiteral:) Creates a set containing the elements of the given array literal. ``` init(arrayLiteral elements: Element...) ``` ## Parameters `elements` A variadic list of elements of the new set. ## Discussion Do not call this initializer directly. It is used by the compiler when you use an array literal. Instead, create a new set using an array literal as its value by enclosing a comma-separated list of values in square brackets. You can use an array literal anywhere a set is expected by the type context. Here, a set of strings is created from an array literal holding only strings. ``` let ingredients: Set = ["cocoa beans", "sugar", "cocoa butter", "salt"] if ingredients.isSuperset(of: ["sugar", "salt"]) { print("Whatever it is, it's bound to be delicious!") } // Prints "Whatever it is, it's bound to be delicious!" ``` --- Copyright © 2026 Apple Inc.
