Generic Structure

ForEach

A structure that computes views on demand from an underlying collection of of identified data.

Declaration

@frozen struct ForEach<Data, Content> where Data : RandomAccessCollection, Content : View, Data.Element : Identifiable

Topics

Type Aliases

typealias ForEach.Body
typealias ForEach.Modified

The type resulting from applying a view modifier T.

Initializers

init(Data, content: (Data.Element.IdentifiedValue) -> Content)

Creates an instance that uniquely identifies views across updates based on the identity of the underlying data element.

init<Base, ID>(Base, id: KeyPath<Base.Element, ID>, content: (Base.Element) -> Content)

Instance Properties

var content: (Data.Element.IdentifiedValue) -> Content

A function that can be used to generate content on demand given underlying data.

var data: Data

The collection of underlying identified data.
