This is because the types of CampaignDetailsView and Text don't match. You need to use a @ViewBuilder (or just a Group, VStack etc).

Here is a solution with the destination view as a @ViewBuilder computed property:

@ViewBuilder
var destinationView: some View {
    if cardCampaigns.count > 0 {
        CampaignDetailsView(viewModel: CampaignDetailsViewModel(campaign: cardCampaigns[self.count].campaign))
    } else {
        Text("No Campaign found")
    }
}

Which you can use like this:

NavigationLink(destination: destinationView) { ... }
