WidgetKit Image from URL

I'm trying to load an image from URL to a Widget. I've done so before just fine in another project I've recently made. Now I'm trying to do the same exact method and seeing some strange errors Argument type 'URL' does not conform to expected type 'Decoder' and Cannot convert value of type 'ExampleWidgetExtension.Data' to expected argument type 'Foundation.Data'. My other project works just fine and I'm using Codable data just like before. Everything but the image seems to be working.

struct ExampleWidgetEntryView : View {
    var entry: Provider.Entry

    var body: some View {
        VStack (alignment: .leading, spacing: 5) {
            ForEach(entry.model?.example.results?.prefix(1) ?? [], id: \.id) { example in
                /*
                 Text(example.data.title ?? "")
                 .fontWeight(.bold)
                 .font(Font.system(.caption))
                 .lineLimit(1)
                 */
                if let url = URL(string:example.data.url ?? ""),
                   let imageData = try? Data(from: url),
                   let uiImage = UIImage(data: imageData) {
                    Image(uiImage: uiImage)
                        .resizable()
                        .frame(width: 30, height: 30)
                }
            }
        }
        .padding(.all, 10)
    }
}

There is no initializer on Data (the one in Foundation) that takes a URL in the from: field. The reason that you're getting an error is that Data(from:) expects a Decoder in that argument. You say that you have another project where you do that, but you must have some sort of custom extension on Data for that to work.

What you want is let imageData = try? Data(contentsOf: url)

As pawello points out in the comments, in looks like you may have a custom type in your project named `Data` already, so it may be necessary to do the following: 
try? Foundation.Data(contentsOf: url)

You may want to consider renaming your Data type to something else to avoid namespace collisions with Foundation's Data
