typealias Body = some View -

When you implement a custom view, you must implement a computed

Return a view that’s composed of built-in views that SwiftUI provides, plus other composite views that you’ve already defined:struct MyView: View { var body: some View { Text("Hello, World!") } }For more information about composing views and a view hierarchy, see doc:Declaring-a-Custom-View.
