iOS: Add hints

User: I want to provide hints on the game pages. When aa user presses a button, it should open some kind of popup that displays hints. Oh by the way, I renamed "SoftCounts" and "HardCounts" to "SoftTotals" and "HardTotals" because it's a better name. Here is the current code for SplitView.swift


import SwiftUI

struct SplitsView: View {
    @State private var playerCard1: Int
    @State private var playerCard2: Int
    @State private var dealerCard: Int
    @State private var feedbackMessage: String
    @State private var backgroundColor: Color
    
    init() {
        let card = Utility.randomCard()
        playerCard1 = card
        playerCard2 = card
        dealerCard = Utility.randomCard()
        feedbackMessage = ""
        backgroundColor = .clear
    }
    
    var body: some View {
        VStack(spacing: 16) {
            Text(feedbackMessage)
            HStack {
                Text("Dealer: ")
                CardView(card: dealerCard)
            }
            HStack {
                Text("You: ")
                CardView(card: playerCard1)
                CardView(card: playerCard2)
            }

            SplitButtonsView(playerCard1: $playerCard1, playerCard2: $playerCard2, dealerCard: $dealerCard, feedbackMessage: $feedbackMessage, backgroundColor: $backgroundColor)

            ActionButton(title: "Deal", backgroundColor: Color.green, action: {
                let newCard = Utility.randomCard()
                playerCard1 = newCard
                playerCard2 = newCard
                dealerCard = Utility.randomCard()
                feedbackMessage = ""
                backgroundColor = .clear
            })
        }
        .padding()
        .background(backgroundColor)
    }
}

struct SplitButtonsView: View {
    @Binding var playerCard1: Int
    @Binding var playerCard2: Int
    @Binding var dealerCard: Int
    @Binding var feedbackMessage: String
    @Binding var backgroundColor: Color
    
    let actions: [String] = ["Split", "Don't Split"]
    
    var body: some View {
        HStack {
            ForEach(actions, id: \.self) { action in
                ActionButton(title: action, backgroundColor: Color.blue, action: {
                    handleAction(action: action)
                })
            }
        }
    }
    
    private func handleAction(action: String) {
        let (shouldSplit, reason) = Utility.shouldSplitCards(playerCard1: playerCard1, playerCard2: playerCard2, dealerCard: dealerCard)
        if (action == "Split" && shouldSplit) || (action == "Don't Split" && !shouldSplit) {
            feedbackMessage = "Correct! \(reason)"
            backgroundColor = .clear
        } else {
            feedbackMessage = "Incorrect. \(reason)"
            backgroundColor = .red
        }
    }
}

struct SplitsView_Previews: PreviewProvider {
    static var previews: some View {
        SplitsView().preferredColorScheme(.dark)
    }
}

Thanks!

To add a hint popup in your SplitsView, you can use a ZStack to overlay a modal view on top of the existing content, and use an @State variable to control its visibility. Here's how to implement this feature:

Add a new @State variable to control the visibility of the hint popup:

@State private var isHintVisible: Bool = false

Create a button in your SplitsView to toggle the visibility of the hint popup:

Button("Show Hint") {
    isHintVisible.toggle()
}
.padding()
.background(Color.orange)
.foregroundColor(.white)
.cornerRadius(8)

Wrap your existing VStack in a ZStack and add a conditional view for the hint popup:

ZStack {
    VStack(spacing: 16) {
        // Existing content
    }
    .padding()
    .background(backgroundColor)
    
    if isHintVisible {
        HintPopupView(hintText: "Your hint text here.", onClose: {
            isHintVisible = false
        })
    }
}

Create a new SwiftUI view for the hint popup:

struct HintPopupView: View {
    let hintText: String
    let onClose: () -> Void
    
    var body: some View {
        VStack {
            Text(hintText)
                .padding()
            
            Button("Close") {
                onClose()
            }
            .padding()
            .background(Color.red)
            .foregroundColor(.white)
            .cornerRadius(8)
        }
        .frame(width: 300, height: 200)
        .background(Color.white)
        .cornerRadius(16)
        .shadow(radius: 10)
    }
}

Now, when the user taps the "Show Hint" button, the hint popup will appear on top of the existing content. The user can close the popup by tapping the "Close" button.

You can follow the same approach to add hint popups to your SoftTotalsView and HardTotalsView. Make sure to customize the hint text for each training game as needed.

User: Ok but we need to work on the design of that HintPopupView.

To improve the design of the HintPopupView, consider the following suggestions:

Add a title to the popup to indicate that it's a hint.

Use a more subtle background color for the popup to make it visually appealing.

Adjust the font size, weight, and style for better readability.

Add some padding and spacing to improve the layout.

Customize the "Close" button to make it more consistent with the overall design.

Here's an updated version of the HintPopupView with these design improvements:

struct HintPopupView: View {
    let hintText: String
    let onClose: () -> Void

    var body: some View {
        VStack(spacing: 16) {
            Text("Hint")
                .font(.system(size: 24, weight: .bold))
            
            Text(hintText)
                .font(.system(size: 18, weight: .medium))
                .multilineTextAlignment(.center)
                .padding(.horizontal)
            
            Button(action: onClose) {
                Text("Close")
                    .font(.system(size: 16, weight: .semibold))
                    .padding(.horizontal, 24)
                    .padding(.vertical, 8)
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(8)
            }
        }
        .padding()
        .frame(width: 300)
        .background(Color(.systemGray6))
        .cornerRadius(16)
        .shadow(radius: 10)
    }
}

This updated design includes a title, adjusted font sizes and weights, and improved spacing and layout. Feel free to further customize the design to match your app's style and preferences.

User: Ok here's the hint I want to include. Where do I put it in the code? Outside of body? Outside of the view?

Always split aces and 8s
Never split 5s
Split 2s, 3s, 7s against 2-7
Split 4s against 5 or 6
Split 6s against 2-6
Split 9s against 2-6 and 8-9

Thanks

You can store the hint text as a constant property within the SplitsView and pass it to the HintPopupView. Here's how to do it:

Add a constant property for the hint text in the SplitsView:

struct SplitsView: View {
    ...
    private let hintText: String = """
    Always split aces and 8s
    Never split 5s
    Split 2s, 3s, 7s against 2-7
    Split 4s against 5 or 6
    Split 6s against 2-6
    Split 9s against 2-6 and 8-9
    """
    ...
}

Pass the hintText property to the HintPopupView when creating it within the ZStack:

ZStack {
    ...
    if isHintVisible {
        HintPopupView(hintText: hintText, onClose: {
            isHintVisible = false
        })
    }
}

Now, the hint text you provided will be displayed in the HintPopupView when the user taps the "Show Hint" button. You can follow a similar approach to add hint text for the SoftTotalsView and HardTotalsView.

User: Make the hint left-aligned

To make the hint text left-aligned in the HintPopupView, you can simply update the multilineTextAlignment modifier for the Text view displaying the hint text. Change it from .center to .leading:

struct HintPopupView: View {
    let hintText: String
    let onClose: () -> Void

    var body: some View {
        VStack(spacing: 16) {
            Text("Hint")
                .font(.system(size: 24, weight: .bold))
            
            Text(hintText)
                .font(.system(size: 18, weight: .medium))
                .multilineTextAlignment(.leading) // Change this line
                .padding(.horizontal)
            
            Button(action: onClose) {
                Text("Close")
                    .font(.system(size: 16, weight: .semibold))
                    .padding(.horizontal, 24)
                    .padding(.vertical, 8)
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(8)
            }
        }
        .padding()
        .frame(width: 300)
        .background(Color(.systemGray6))
        .cornerRadius(16)
        .shadow(radius: 10)
    }
}

Now the hint text in the HintPopupView will be left-aligned.

User: Ok great, we should also make the hint go away if the user taps outside the hint box.

To make the hint go away when the user taps outside the hint box, you can add a tap gesture to the background layer of the ZStack. Here's how to do it:

Modify the ZStack in your SplitsView:

ZStack {
    VStack(spacing: 16) {
        // Existing content
    }
    .padding()
    .background(backgroundColor)
    .onTapGesture {
        // Dismiss the hint when tapping outside the hint box
        if isHintVisible {
            isHintVisible = false
        }
    }
    
    if isHintVisible {
        HintPopupView(hintText: hintText, onClose: {
            isHintVisible = false
        })
    }
}

Now, when the user taps outside the hint box, the isHintVisible state variable will be set to false, and the hint popup will be dismissed.

User: actually, I think this hint button should maybe just be a small question mark at the top right corner of the page.

To move the hint button to the top right corner of the page and change it to a small question mark, you can update the SplitsView as follows:

Wrap the existing VStack in another VStack and add a spacer to push the content to the top.

Add an HStack to the outer VStack to create space for the hint button on the top right corner.

Move the hint button into the HStack and add a spacer to push the button to the right.

Update the button style to display a small question mark.

Here's the updated SplitsView:

struct SplitsView: View {
    // Existing state variables and properties

    var body: some View {
        ZStack {
            VStack {
                HStack {
                    Spacer()
                    
                    Button(action: {
                        isHintVisible.toggle()
                    }) {
                        Image(systemName: "questionmark.circle")
                            .font(.system(size: 24))
                            .foregroundColor(.blue)
                    }
                    .padding(.trailing)
                }
                
                VStack(spacing: 16) {
                    // Existing content
                }
                .padding()
                .background(backgroundColor)
                
                Spacer()
            }
            
            if isHintVisible {
                HintPopupView(hintText: hintText, onClose: {
                    isHintVisible = false
                })
            }
        }
    }
}

Now, the hint button will appear as a small question mark at the top right corner of the page. You can follow a similar approach to update the SoftTotalsView and HardTotalsView.

User: Because of the Back navigation, this doesn't look very good.

To address the issue with the "Back" navigation and the hint button, you can use a ZStack to overlay the hint button on top of the navigation bar. Here's how to update the SplitsView:

Wrap the existing VStack in a ZStack:

struct SplitsView: View {
    // Existing state variables and properties

    var body: some View {
        ZStack {
            VStack {
                // Existing content
            }
            .padding()
            .background(backgroundColor)

            // Add the hint button here
        }
        .navigationBarItems(trailing: hintButton)
    }

    // Create a separate view for the hint button
    private var hintButton: some View {
        Button(action: {
            isHintVisible.toggle()
        }) {
            Image(systemName: "questionmark.circle")
                .font(.system(size: 24))
                .foregroundColor(.blue)
        }
    }
}

Now, the hint button will be displayed in the navigation bar's trailing position, and it won't interfere with the "Back" navigation.

You can follow a similar approach to update the SoftTotalsView and HardTotalsView. Make sure to add the .navigationBarItems(trailing: hintButton) modifier to each view and create the hintButton view as shown above.

                    .foregroundColor(.white)
                    .cornerRadius(8)

This updated code includes the hint button in the top right corner, the hint popup with left-aligned text, and the ability to dismiss the hint popup by tapping outside the hint box.

User: Ok I changed my mind. Tapping anywhere on the screen should dismiss the popup. How should I change my code?

To make the hint popup dismiss when tapping anywhere on the screen, you can add a tap gesture to the HintPopupView itself. Here's how to update the HintPopupView:

Add a .onTapGesture modifier to the VStack in the HintPopupView:

struct HintPopupView: View {
    let hintText: String
    let onClose: () -> Void

    var body: some View {
        VStack(spacing: 16) {
            // Existing content
        }
        .padding()
        .frame(width: 300)
        .background(Color(.systemGray6))
        .cornerRadius(16)
        .shadow(radius: 10)
        .onTapGesture {
            onClose()
        }
    }
}

Now, when the user taps anywhere on the hint popup, the onClose closure will be called, and the hint popup will be dismissed.

User: This only works if I click on the Popup. Maybe I should do the following: "Make a full screen view with a ZStack containing a view that is translucent, and put your alert on top of that. Add a tap gesture to the translucent view that dismisses the entire view"

To create a full-screen translucent view with the hint popup on top and dismiss the entire view when tapping anywhere, follow these steps:

Update the HintPopupView to include a full-screen translucent background.

Add a ZStack inside the HintPopupView to put the hint content on top of the translucent background.

Add a tap gesture to the translucent background view.

Here's the updated HintPopupView:

struct HintPopupView: View {
    let hintText: String
    let onClose: () -> Void

    var body: some View {
        ZStack {
            // Full-screen translucent background
            Color.black.opacity(0.4)
                .edgesIgnoringSafeArea(.all)
                .onTapGesture {
                    onClose()
                }

            // Hint content
            VStack(spacing: 16) {
                Text("Hint")
                    .font(.system(size: 24, weight: .bold))

                Text(hintText)
                    .font(.system(size: 18, weight: .medium))
                    .multilineTextAlignment(.leading)
                    .padding(.horizontal)

                Button(action: onClose) {
                    Text("Close")
                        .font(.system(size: 16, weight: .semibold))
                        .padding(.horizontal, 24)
                        .padding(.vertical, 8)
                        .background(Color.blue)
                        .foregroundColor(.white)
                        .cornerRadius(8)
                }
            }
            .padding()
            .frame(width: 300)
            .background(Color(.systemGray6))
            .cornerRadius(16)
            .shadow(radius: 10)
        }
    }
}

Now, when the user taps anywhere on the screen, the onClose closure will be called, and the hint popup will be dismissed.
