Extra argument in call inside Group View

Question

I have a sccreen on my witch only displays text but when i try to add more than 10 views inside my Group View i'm getting this error. I tried to wrap the VStack with the Group View but nothing changed

Extra argument in call

My code:

struct GoalTipsView: View {
    
    var body: some View {
        
        NavigationView {
            
            ScrollView {
                
                VStack(alignment: .leading) {
                    
                    Group {
                        
                        HStack(spacing: 5) {
                            Text("Using the")
                            Text("Smart").bold()
                            Text("format is important for")
                            Spacer()
                        }.padding(.leading, 7)
                        
                        HStack(spacing: 5) {
                            Text("structuring goals correctly and increases the")
                        }.padding(.leading, 7)
                        
                        HStack(spacing: 5) {
                            Text("chance of success").bold()

This is SwiftUI limitation: you can't have more than 10 views on the same level inside any container.

This is because of how SwftUI is built. Imagine each @ViewBuilder function has implementations like this:

func viewBuilder(_ argument1: some View)
func viewBuilder(_ argument1: some View, _ argument2: some View)
...
func viewBuilder(_ argument1: some View, _ argument2: some View, ..., _ argument10: some View)

They had to stop at some point, and it's 10.

You can place your views inside one more Group: this is one of the cases it was made for. Also you can move them into a @ViewBuilder func subgroup() -> some View {}

struct GoalTipsView: View {

    var body: some View {

        NavigationView {

            ScrollView {

                VStack(alignment: .leading) {

                    Group {
                        Group {
                            HStack(spacing: 5) {
                                Text("Using the")
                                Text("Smart").bold()
                                Text("format is important for")
                                Spacer()
                            }.padding(.leading, 7)

                            HStack(spacing: 5) {
                                Text("structuring goals correctly and increases the")
                            }.padding(.leading, 7)

                            HStack(spacing: 5) {
                                Text("chance of success").bold()
                            }.padding(.leading, 7)
                                .padding(.bottom, 35)

                            HStack(spacing: 5) {
                                Text("SPECIFIC").bold().font(.system(size: 23))
                            }.padding(.leading, 10)

                            HStack(spacing: 5) {
                                Text("(Goals that are simple, sensible, significant.) \n A specific goal allows you to focus on a clear and specific target. It can help you visualise the desired outcome and makes it easier to track your progress. Focusing the mind on the desired goals is important for success.

                                    .padding(5)
                            }.padding(.leading, 7)

                            HStack(spacing: 5) {
                                Text("MEASURABLE").bold().font(.system(size: 23))
                            }.padding(.leading, 10)
                                .padding(.top, 23)

                            HStack(spacing: 5) {
                                Text("(goals that are meaningful, motivating.) \n If your goal isn't measurable, there will be no way to determine if it\'s achieved.

                                    .padding(5)
                            }.padding(.leading, 10)

                            HStack(spacing: 5) {

                            }

                                .padding(.top, 23)
                        }


                        HStack(spacing: 5) {} // Extra argument in call


                    }

                }.padding(.top, 10)

            }.navigationBarHidden(true)

        }

    }
