How create an empty array of "View" on SwiftUI?

Question

I wanted to have an empty array of "View" in SwiftUI and fill it later.

When I write it like this:

 @State var pages: [View]

XCode yells at me with this:

Protocol 'View' can only be used as a generic constraint because it has Self or associated type requirements

I would highly not recommend to do that, but if you do like then there are two possible options

either declare as of view type erasure

@State var pages = [AnyView]()

or your specific concrete page type, let's assume it is PageView

@State var pages = [PageView]()

for option1 I get this error when I want to fill the pages variable: Cannot convert value of type 'YourView.page1.Type' to expected element type 'Array<AnyView>.ArrayLiteralElement' (aka 'AnyView')

Option2 is not possible too, I want to use the exact View thing, a complete page for that

Aha ! I should cast my final view to AnyView!
