# init(_:content:) Creates an instance that computes views on demand over a given constant range. ``` @export(implementation) init(_ data: Range, @ContentBuilder content: @escaping (Int) -> Content) ``` ## Parameters `data` A constant range. `content` The content builder that creates views dynamically. ## Discussion The instance only reads the initial value of the provided `data` and doesn’t need to identify views across updates. To compute views on demand over a dynamic range, use `ForEach/init(_:id:content:)`. --- Copyright © 2026 Apple Inc.
