# element(_:) Enforces a guide on the elements within the array. ``` static func element(_ guide: GenerationGuide) -> GenerationGuide<[Element]> where Value == [Element] ``` ## Discussion An `element` generation guide may be used when you want to apply guides to the values a model produces within an array. For example, you may want to generate an array of integers, where all the integers are in the range 0-9. ```swift @Generable struct FortuneCookie { @Guide(description: "A fortune from a fortune cookie") var name: String @Guide(description: "A list lucky numbers", .element(.range(0...9)), .count(4)) var luckyNumbers: [Int] } ``` --- Copyright © 2026 Apple Inc.
