hey, what exactly is your issue? I'm using Charts in a SwiftUI project just fine. Can you maybe post your code as source code instead of an image?

Hi, yeah you can take this Try with use widget preview, when I start preview on phone it work good.

` import Charts import SwiftUI import WidgetKit

struct Bar : UIViewRepresentable {

var entries : [BarChartDataEntry]

func makeUIView(context: Context) -> BarChartView {

    let chart = BarChartView()

    chart.data = addData()

    return chart

}

func updateUIView(_ uiView: BarChartView, context: Context) {

    uiView.data = addData()

}

func addData() -> BarChartData{

    let data = BarChartData()

    let dataSet = BarChartDataSet(entries: entries)

    data.addDataSet(dataSet)

    return data

}

typealias UIViewType = BarChartView

}

struct Bar_Previews: PreviewProvider {

static var previews: some View {

    Bar(entries: [BarChartDataEntry(x: 1, y: 1)])
    .previewContext(WidgetPreviewContext(family: .systemMedium))
}

}`

I'm confused now. Is you problem just with the XCode SwiftUI preview or when actually running the app/widget? Your ticket description is not quite clear

@JanC sorry for that, problem in both situation when run app on simulator and on preview

@ClayPwr

UIKit views wrapped in UIViewRepresentable will not work in WidgetKit.
