Ich habe ein Code in Swift geschrieben und bekomme zwei Fehler wo ich nicht weiß wie ich sie beheben kann

Meine Dateien:

AppState:

import Foundation

class AppState: ObservableObject {
    @Published var isLockedIn = false
}

ContentView:

import SwiftUI
import LocalAuthentication

struct LoginView: View {
    @State private var unlocked = false
    @State private var text = "Gespert"
    @EnvironmentObject var appState = AppState()
    var body: some View {
        VStack {
            Text(text)
                .bold()
                .padding()
            Button("Entsperen") {
                authenticate()
            }
        }
    }
    
    func authenticate() {
        let context = LAContext()
        var error: NSError?
        
        if context.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &error) {
            context.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, localizedReason: "Das ist zum entsperren der App") {
                success, authenticatinError in 
                
                if success {
                    text = "ENTSPERT"
                    appState.isLockedIn = true
                    
                }else {
                    text = "ES GAB EIN PROBLEM"
                }
            }

    }
}

// MARK: - Preview
struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        LoginView()
    }
}

MyApp:

import SwiftUI

@main
struct MyApp: App {
    
    @StateObject private var appState = AppState()
    
    var body: some Scene {
        WindowGroup {
            if !appState.isLockedIn {
                LoginView()
                    .environmentObject(appState)
            }else {
                ContentView()
            }
        }
    }
}

Die Fehler sind :
Argument passed to call that takes no argument
Und
Generic parameter ˋObjectType ´ could not inferred

Ich habe keine Ahnung was man probieren kann da ich relativ neu bei Swift bin
