Having issues with navigation view (SwiftUI, iOS)

Question

Code below:

NavigationView{
            ZStack{
                Color("SmokyBlack").ignoresSafeArea()
                VStack{
                    //ModularContent(titleName: titleName, subtitleText: subtitleText, imageName: imageName)
                        
                    NavigationLink(destination: SecondOnboardingView()){
                        OnboardingButton(buttonText: btnName, updateOnboarding: false)
                    }
                }
            }// parent vstack
            .preferredColorScheme(/*@START_MENU_TOKEN@*/.dark/*@END_MENU_TOKEN@*/)
            .navigationBarHidden(true)
        } //nav view ends

The button is clearly being pressed but nothing is happening

edit: code for the button. I have tried changing this button to plain text but it still doesn't work.

struct OnboardingButton: View {
    var buttonText: String
    var updateOnboarding: Bool
    
    @AppStorage("onboardingCheck") var onboardingCheck: Bool?
    
    var body: some View {
        Button(action: {onboardingCheck=updateOnboarding},
            label: {
                ZStack{
                    RoundedRectangle(cornerRadius: 5)
                        .foregroundColor(.white)
                        .frame(width: 300, height: 60, alignment: .center)
                    Text(buttonText)
                        .foregroundColor(.black)
                        .font(.system(size: 20))
                        .fontWeight(.semibold)
                }
            })
            
    }
}

Answer 1

I seem to have figured out why.

Button(action: {onboardingCheck=updateOnboarding}, from OnboardingButton seems to only accept true as an answer to continue. To work around this, I simply made a different file that does not use Button() but instead the following:

struct OnboardingButtonTwo: View {
    var buttonText: String
    var body: some View {
        ZStack{
            RoundedRectangle(cornerRadius: 5)
                .foregroundColor(.white)
                .frame(width: 300, height: 60, alignment: /*@START_MENU_TOKEN@*/.center/*@END_MENU_TOKEN@*/)
            Text(buttonText)
                .foregroundColor(.black)
                .font(.system(size: 20))
                .fontWeight(.semibold)
        }
        .padding(.bottom, 10)
    }
}
