LayoutWriter

public struct LayoutWriter : Element

A parent element which allows arbitrary, custom layout and positioning of its children.

Instead of creating a custom Element with a custom Layout, you might use this element to create a customized layout in a more lightweight way.

LayoutWriter { context, layout in
    layout.add(with: myFrame, child: myElement)
    layout.add(with: myOtherFrame, child: myOtherElement)

    layout.sizing = .unionOfChildren
}

Initialization

  • Creates a new instance of the LayoutWriter with the custom layout provided by the builder.

    The parameters to the closure are the Context, which provides information about the environment and sizing of the layout, and the Builder itself, which you use to add child elements to the layout.

    Declaration

    Swift

    public init(_ build: @escaping Build)

  • The builder type passed to the LayoutWriter initializer.

    Declaration

    Swift

    public typealias Build = (Context, inout Builder) -> Void

  • The builder used to create the custom layout.

    Declaration

    Swift

    public let build: Build

  • Declaration

    Swift

    public func backingViewDescription(with context: ViewDescriptionContext) -> ViewDescription?

  • The builder is the primary surface area you interact with when using a LayoutWriter.

    It provides you the ability to manage the sizing and measurement of the final layout, alongside methods to add and manage the children of the layout.
