How to use TabView with enum in SwiftUI

enum Authentication: Int, Codable {
    case key
    case certificate
}


TabView(selection: $authentication) {
    KeyAuthenticationView()
        .tabItem {
            Text("🔑 Key")
        }
        .tag(Authentication.key)
    CertificateAuthenticationView()
        .tabItem {
            Text("📰 Certificate")
        }
        .tag(Authentication.certificate)
}
