Asynchronous navigation

Generic way: you can use asynchronous navigation in the view model as follows

@MainActor func adoptCat() async {
	var selectedCat: CatModel = await navigation.pushViewGenericAsync(
		view: CatAdoptView(),
		animated: true,
		enableSwipeBack: true,
		title: "",
		titleHidden: true, 
		defaultValue: CatModel.aNewCat
	)
}

Collback way: you can use asynchronous navigation in the view model as follows

@MainActor func adoptCat() async {
	var selectedCat = CatModel.aNewCat
	await navigation.pushViewAsync(
		view: CatAdoptView(
			onCatSelect: { cat in
				selectedCat = cat
				self.navigation.popViewAsync()
			}
		),
		animated: true
	)
}
