I started with a clean project and added 5 buttons and 5 spacers in a VStack and all is good. When I add the 6th spacer at the bottom, the code suddenly won't compile with the error: "Ambiguous reference to member 'buildBlock()'".

What is causing this error? Is this a bug related to SwiftUI? Or is it a feature? It's not the first time I notice that VStack or HStack is limited in the number of entries, is there some documentation around this?

Not exactly confidence inspiring, should I switch back to UIKit?
