我目前正在为登录和注册我的IOS应用程序的用户路径作为一个初学者，我需要有我的代码，我如何当电子邮件地址是有效的，并在我目前的项目中更改视图的意见，我已经创建了不同的屏幕几个视图
先谢谢你了

import SwiftUI

struct Registration: View {
    // MARK: - Properties
    @State private var email = ""
    @State private var Error = false
    @State private var ValidationButton = false
    
    // Check email
    var isEmailValid: Bool {
        let emailRegex = #"^[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}$"#
        return NSPredicate(format: "SELF MATCHES %@", emailRegex).evaluate(with: email)

                        }

                .frame(maxHeight: 50)
                
            }
            .padding(.horizontal, 16)
            .background(Color(.systemBackground))
            .navigationBarHidden(true)
        }
        .navigationViewStyle(StackNavigationViewStyle())
    }
}

struct RegistrationView_Previews: PreviewProvider {
    static var previews: some View {
        Registration()
    }
}

为了解决我的问题，我试图通过在苹果官方文档上查找一个NavigationLink，但它不起作用，我不知道这是否是好方法，谢谢你
