iPhone keyboard dissapear and appear again when switching between fields with onTapGesture(hideKeyboard)

I have this code in Swift (iOS 16+) and I have a login screen into my app, where the user needs to enter an email and password.

I also have a .onTapGesture method on the GeometryReader { ... } wrapping everything together. I want the user to be able to dismiss the keyboard when tapping away from the text field.

But when the user enters an email and then wants to enter a password, the keyboard disappear and then appears again. How can I do that so the keyboard stays open (same expecting result as without the onTapGesture).

Here is my code

struct LoginView: View {
    
    @Environment(\.horizontalSizeClass) var horizontalSizeClass
    
    @State var email: String = ""
    @State var password: String = ""
    
    private let hapticFeedbackService = HapticFeedbackService()
    
    var body: some View {
        GeometryReader { screenGeometry in
            let screenHeight = screenGeometry.size.height
            
            ZStack {
                Color.black.background.ignoresSafeArea(.all)
                
                VStack {
                    WelcomeTextView(welcomeText: "sign_in_to")
                        .frame(maxWidth: .infinity, alignment: .leading)
                        .padding(.top, screenHeight * 0.02)
                    
                    VStack {
                        InputField(
                            text: $email,
                            placeholder: "enter_email",
                            isSecure: false
                        )
                        .padding(.bottom, 15)
                        
                        InputField(
                            text: $password,
                            placeholder: "enter_password",
                            isSecure: true,
                            trailingIcon: Image("Lock")
                        )
                    }
                    
                    Button(action: {
                        hapticFeedbackService.triggerHapticFeedback()
                        print("Button pressed")
                    }) {
                        Text(LocalizedStringKey("forgot_your_password"))
                            .font(.thinnerSmallTitle)
                    }
                    .padding(.top, 5)
                    .padding(.trailing, 5)
                    .frame(maxWidth: .infinity, alignment: .trailing)
                    
                    LargeButton(
                        text: "sign_in",

                        print("Button pressed")
                    }
                    .padding(.top, 40)

                        SSOButton(type: .Apple, action: {

                        SSOButton(type: .Google, action: {
                            hapticFeedbackService.triggerHapticFeedback()
                            print("Button pressed")
                        })
                        .padding(.leading, 5)
                    }
                    .padding(.top, 10)
                    
                    HStack {
                        Text(LocalizedStringKey("dont_have_account"))
                            .font(.mediumText)

    }
    
    private func hideKeyboard() {
        // UIApplication.shared.keyWindow?.endEditing(true) - Deprecated
        
        UIApplication.shared.sendAction(
            #selector(UIResponder.resignFirstResponder),
            to: nil,
            from: nil,
            for: nil
        )
    }
}

Thank you.

Solution

One another solution is like

on your ZStack

ZStack {
       Color.yellow.frame(maxWidth: .infinity, maxHeight: .infinity).onTapGesture {
                        hideKeyboard()
                    }

And at the bottom no need to give tap geture to your entire ZStack

ZStack {
//Your code
 }
        .ignoresSafeArea(.keyboard)
        .onTapGesture { self.hideKeyboard() }

It should work.
