按钮未点击

如何解决按钮未点击

使用SwiftUI。由于某些非常奇怪的原因，此按钮不可单击（它出现但不执行其动作任务）。当我将Button放在HStack外面时，它突然工作了。我是愚蠢的还是它的错误。谢谢！

    ZStack{
        Image("Background")
            .resizable()
            .edgesIgnoringSafeArea([.top,.bottom])
        
        vstack{
            HStack{
                Text("Dari Learner")
                .font(.largeTitle)
                .foregroundColor(Color.white)
                .padding(.top,50)
                .padding(.leading,90)
            
            
            Button(action: {
                print("Button Tapped")
                self.viewmodel.createQuiz()
            }) {
                        Text("Next")
                            .background(Color.green.opacity(0.5))
                            .cornerRadius(25)
                            .opacity(self.dim ? 1 : 0)
                        
                    .transition(.scale)
                        .animation(.easeInOut(duration: 1.5))
            }// !disabled because this is also used for the answerbubbles
            }
            
            ZStack{
                AnswerBubble(fillColor: Color.black,isChosen: false)
                Text(viewmodel.getActualAnswer().word.DariWord)
            }
            
            
            Grid(viewmodel.answers) { answer in
                
                QuizView(answer: answer,fillColor: self.colorFor(answer: answer,correctAnswer: self.viewmodel.getActualAnswer())).onTapGesture {
            
                    self.tappedAnswers.append(answer)
                        
                    if self.viewmodel.chooseAnswer(answer: answer){
                        self.dim.toggle()
                        self.disabled.toggle()
                    }
                }
                .animation(.easeInOut(duration: 1.0))
                .disabled(self.disabled)
            }
        }
        .edgesIgnoringSafeArea([.top])
    }.ondisappear{
        self.viewmodel.createQuiz()
    }
