'main()' is only available in application extensions for iOS 14.0 or newer

Question

I added widget target in my app, and I tried to the iOS 14 and newer condition for that, but I still got this error:

'main()' is only available in application extensions for iOS 14.0 or newer

@available(iOSApplicationExtension 14.0, *)
@main
struct Widget: SwiftUI.Widget {
    let kind: String = "Widget"

   var body: some WidgetConfiguration {
        IntentConfiguration(kind: kind, intent: ConfigurationIntent.self, provider: Provider()) { entry in
            WidgetEntryView(entry: entry)
        }
        .configurationDisplayName("My Widget")
        .description("This is an example widget.")
    }
}

That @available is the one that Xcode suggested me

Could anyone help me on that?

Answer 1

In the file where your put '@main', look at the target membership on the right sidebar, remove your main app as a target and leave your widget extension.

Answer 2

If you added or already had an extension you should check that the deployment info for you extension is 14.0.
