Pushing a second view

[jem5519]

I have my first screen showing up. From that screen I want to push a second screen.

I have code like this:

if appModel.stageViewState == .one
{
router.showScreen(.push) { router in
TestView01()
}
}
inside the body of the previous view.

I get a syntax error:

Type '()' cannot conform to 'View

Is there a better way of doing this?
