View
-
The type of view representing the body of this view.
When you create a custom view, Swift infers this type from your implementation of the required
View/body-swift.propertyproperty.Declaration
Swift
typealias Body = some View -
The content and behavior of the view.
When you implement a custom view, you must implement a computed
bodyproperty to provide the content for your view. 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 .
Declaration
Swift
@MainActor @preconcurrency var body : some View { get }
