To create a custom AnyLayout in SwiftUI, you can define a property of type AnyLayout that resolves to different layouts based on certain conditions. For example, in the session "Get started with Dynamic Type," a dynamic layout is created that switches between an HStack and a VStack depending on the text size. Here's a simplified example:

struct ContentView: View {
    @Environment(\.dynamicTypeSize) var dynamicTypeSize
    var dynamicLayout: AnyLayout {
        if dynamicTypeSize.isAccessibilitySize {
            return AnyLayout(VStackLayout())
        } else {
            return AnyLayout(HStackLayout())
        }
    }

    var body: some View {
        dynamicLayout {
            Image(systemName: "star")
            Text("Dynamic Layout")
        }
    }
}

This code snippet demonstrates how to use AnyLayout to dynamically switch between a vertical and horizontal layout based on the accessibility size of the text. This approach allows for flexible and adaptive UI designs in SwiftUI.

For more details, you can refer to the session Get started with Dynamic Type (06:00).
