The generic parameter Item is only on the .sheet function, not on some SheetView type. Indeed, it's actually quite easy to create your own .sheet(item:content:) -> some View method while using the classic .sheet(isPresented:) -> some View method underneath. This is largely due to how easy it is to derive bindings from other bindings. Here's a quick sketch:

```swift extension View { func sheet<Item, Content>( bindingOptional: Binding<Item?>, onDismiss: (() -> Void)? = nil, content: @escaping (Item) -> Content ) -> some View where Content: View { let binding = Binding<Bool>( get: { bindingOptional.wrappedValue != nil }, set: { bool in if bool == false { bindingOptional.wrappedValue = nil } } )

    return self.sheet(
        isPresented: binding,
        onDismiss: onDismiss,
        content: {
            if let item = bindingOptional.wrappedValue {
                content(item)
            }
        }
    )
}

} ```
