# AnyLayout

A type-erased instance of the layout protocol.

## Declaration

```swift
@frozen struct AnyLayout
```

## Overview

Overview Use an AnyLayout instance to enable dynamically changing the type of a layout container without destroying the state of the subviews. For example, you can create a layout that changes between horizontal and vertical layouts based on the current Dynamic Type setting: struct DynamicLayoutExample: View {     @Environment(\.dynamicTypeSize) var dynamicTypeSize

var body: some View {         let layout = dynamicTypeSize <= .medium ?             AnyLayout(HStackLayout()) : AnyLayout(VStackLayout())

layout {             Text("First label")             Text("Second label")         }     } } The types that you use with AnyLayout must conform to the Layout protocol. The above example chooses between the HStackLayout and VStackLayout types, which are versions of the built-in HStack and VStack containers that conform to the protocol. You can also use custom layout types that you define.
