Can't figure out error code

I try to create a topic in the app dev section but get this error:

An error occurred: Sorry, new users can only mention 2 users in a post.

No idea what it means.

If you have tried to add code to your post which includes @State or @Environment or any swift wrapper, without formatting the code as a “code block” so that it appears like this:

struct ContentView: View {
    @State var screenWidth = UIScreen.main.bounds.width
    let plotPoints = [5, 20, 16, 7, 13, 8, 10]
    let maxHeight = 20
    @State private var plots = [ChartPoints]()

    var body: some View {
        VStack {
            GeometryReader { gr in
                HStack(alignment: .bottom, spacing: (screenWidth - 100) / CGFloat(plotPoints.count)) {
                    ForEach(plots, id: \.self) { point in
                        let height = CGFloat(point.point / CGFloat(maxHeight))
                        ZStack {
                            VStack {
                                    .frame(width: 25)
                        .frame(width: 25, height: gr.size.height * height)
        .frame(height: 400)
        .onAppear {
            for point in plotPoints {
                let newPoint = ChartPoints(point: CGFloat(point))

What will happen is that anything that begins with @ will be interpreted as referring to another user.

To format your code as a “code block”, paste in the code and then select all of that code with your cursor and then tap the icon in the editing bar that looks like </>.

What that does is place 3 back-tick characters ``` above the code block and 3 back-tick characters ``` below the code block. The back-tick character is on the same key as the tilde ~ on a QWERTY keyboard.

See if that solves your issue.

Excellent, thank you. Maybe mention it in FAQs or somewhere? Or maybe it is already.
