SwiftUI: Random "Extra argument in call" error

The @ViewBuilder system in SwiftUI is limited to 10 views within any given view container. There's no argument for an 11th view, so you get that error.

Basic solution:

The issue here is that your VStack is at maximum capacity, however you can wrap those existing views inside of other containers. As a very basic example that would allow you to show 10 BottomReceiptRow views:

    var body: some View {
    ZStack {
        Color.white
            .scaledToFit()

// Modifications start here

        VStack {
            if adBannerView.adHasLoaded {
                adBannerView
                    .frame(maxHeight: adBannerView.adHeight)
                    .animation(.easeInOut(duration: 2.0))
            }

            BorderView()

            Text(ARCHLocalizedStrings.receipt)
                .foregroundColor(Color.gray)

            BorderView()

            HStack {
                Spacer()

                Button(action: {
                    self.receiptViewModel.addNewReceiptItem()
                }) {
                    Text(ARCHLocalizedStrings.buttonTitleAddItem)
                }
            }

            BorderView()

            ScrollView {
                ForEach(receiptViewModel.receiptItems) { receiptItem in
                    ItemView(receiptItem: receiptItem)

                    if receiptItem != self.receiptViewModel.receiptItems.last {
                        Divider()
                    }
                }
            }

            BorderView()

            Group {
                BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                                   type: ReceiptRowType.subtotal,
                                   title: ARCHLocalizedStrings.subtotal)

                BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                                   type: ReceiptRowType.tax,
                                   title: ARCHLocalizedStrings.tax)

                BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                                   type: ReceiptRowType.someValue,
                                   title: ARCHLocalizedStrings.someValue)

                BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                                   type: ReceiptRowType.someValue2,
                                   title: ARCHLocalizedStrings.someValue2)

                BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                                   type: ReceiptRowType.someValue3,
                                   title: ARCHLocalizedStrings.someValue3)

                BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                                   type: ReceiptRowType.someValue4,
                                   title: ARCHLocalizedStrings.someValue4)

                BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                                   type: ReceiptRowType.someValue5,
                                   title: ARCHLocalizedStrings.someValue5)
            }
// Modifications end here

        }
        .padding(.horizontal, ARCHSwiftUILayoutConstants.defaultPaddingAndSpacing)
    }
}

Alternatively:

You may prefer to completely refactor these sections into their own View as composition makes the code easier to read. It's not strictly necessary here though.

If you did want to do that, you could consider an example where those receipt rows are all in their own view like:

    var body: some View {
    ZStack {
        Color.white
            .scaledToFit()

        VStack {
            if adBannerView.adHasLoaded {
                adBannerView
                    .frame(maxHeight: adBannerView.adHeight)
                    .animation(.easeInOut(duration: 2.0))
            }

            BorderView()

            Text(ARCHLocalizedStrings.receipt)
                .foregroundColor(Color.gray)

            BorderView()

            HStack {
                Spacer()

                Button(action: {
                    self.receiptViewModel.addNewReceiptItem()
                }) {
                    Text(ARCHLocalizedStrings.buttonTitleAddItem)
                }
            }

            BorderView()

            ScrollView {
                ForEach(receiptViewModel.receiptItems) { receiptItem in
                    ItemView(receiptItem: receiptItem)

                    if receiptItem != self.receiptViewModel.receiptItems.last {
                        Divider()
                    }
                }
            }

            BorderView()

            bottomRow
        }
        .padding(.horizontal, ARCHSwiftUILayoutConstants.defaultPaddingAndSpacing)
    }
}

// Additional computed property in TipView
var bottomRow: some View {
    Group {
        BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                           type: ReceiptRowType.subtotal,
                           title: ARCHLocalizedStrings.subtotal)

        BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                           type: ReceiptRowType.tax,
                           title: ARCHLocalizedStrings.tax)

        BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                           type: ReceiptRowType.someValue,
                           title: ARCHLocalizedStrings.someValue)

        BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                           type: ReceiptRowType.someValue2,
                           title: ARCHLocalizedStrings.someValue2)

        BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                           type: ReceiptRowType.someValue3,
                           title: ARCHLocalizedStrings.someValue3)

        BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                           type: ReceiptRowType.someValue4,
                           title: ARCHLocalizedStrings.someValue4)

        BottomOfReceiptRow(receiptViewModel: receiptViewModel,
                           type: ReceiptRowType.someValue5,
                           title: ARCHLocalizedStrings.someValue5)
    }
} // end bottomRow

try making a Group { } around your views. just 10 are allowed in Swiftui...with group you can add more. or use subviews...(would be cleaner code too)

In SwiftUI you can stack up to 10 views in the same Stack (VStack, HStack, ZStack), so you can Embed some Views inside another Stack or inside Group {}.
