(SwiftUI Charts/ VisionOS) Static method 'buildExpression' requires that 'Chart' conform to 'View'

Question

Trying to create a Chart in ContentView. I keep seeing this error no matter how I try to construct it.

import Foundation
import SwiftUI
import Charts

struct StockView: View {
    var body: some View {
        Chart {
              BarMark(
                 x: .value("Department", "Finance"),
                 y: .value("Profit", 300000)
              )
        }
    }
}


#Preview {
    StockView()
}

Show a minimal reproducible code that produces your issue, see: [minimal code](https://stackoverflow.com/help/minimal-reproducible-example). Show the full error messages you get and on which line of the code. — workingdog support Ukraine, Jul 21 '23 at 07:47
Do you have a custom type named Chart, otherwise follow the advice in the comment above. — Joakim Danielson, Jul 21 '23 at 08:17
It looks like you haven't put the chart into a view class. Look at the example answer below on how to show this — Chris, Jul 21 '23 at 09:03

In my experiment minimum iOS16 or visionOS beta 1 and this code:

import SwiftUI
import Charts

struct ContentView: View {
    var body: some View {
        Chart {
            BarMark(
                x: .value("Department", "Finance"),
                y: .value("Profit", 300000)
            )
        }
    }
}

compile and run.

I am testing this in VisionOS – rkatakam Jul 21 '23 at 22:49

This is valid code for visionOS as well. I suspect you have another struct/class named Chart somewhere which is conflicting with the imported Charts library definition. – svarrall Jul 24 '23 at 04:40
It is working now, thanks. I created a new project and it solved the issue – rkatakam Jul 24 '23 at 23:19
