Hello everyone!

I was putting a figure in my code when I was interrupted by this error that says "Extra argument in call", what does this sentence mean and how can I fix it?

Thanks!

Try this:

let columns: [GridItem] = [GridItem(.flexible()),
                           GridItem(.flexible()),
                           GridItem(.flexible())]

struct ContentView: View {
    var body: some View {

        GeometryReader { geometry in
            VStack{
                Spacer()
                ZStack {

Can you provide an example code snippet? It means that the function you are calling is expecting 2 arguments, and you are trying to pass in 3 arguments.

struct contentView_Previews: PreviewProvider {

}

In the last Circle(), it shows me Error.

You've got more that 10 Views in your LazyVGrid.
Try dividing them into two Group views (5 in one, and 6 in the other).

Crash is affectively at view 11…

"Extra argument in call"

means that you have more than 10 views, overpassing the SwiftUI limit.
