swift - Conditionally use view in SwiftUI

Question

I'm trying to figure out the correct way to conditionally include a view with swiftui. I wasn't able to use the if directly inside of a view and had to use a stack view to do it.

This works but there seems like there would be a cleaner way.

var body: some View {
    HStack() {
        if keychain.get("api-key") != nil {
            TabView()
        } else {
            LoginView()
        }
    }
}

Answer 1

The simplest way to avoid using an extra container like HStack is to annotate your body property as @ViewBuilder, like this:

@ViewBuilder
var body: some View {
    if user.isLoggedIn {
        MainView()
    } else {
        LoginView()
    }
}
