is there a way to provide iOS version check inside widget extension

I tried to add iOS 17 version check inside WidgetBundle but the widget extension keep on crashing .

Getting Thread 1: Swift runtime failure: Unexpectedly found nil while unwrapping an Optional value. After removing the iOS 17 check it works fine.

Is there any way to provide version check inside widgetBundle?

 struct MyWidgets: WidgetBundle {
        @WidgetBundleBuilder
        var body: some Widget {
            widget1()
            widget2()

            if #available(iOSApplicationExtension 16.1, *) {
               LiveActivity()
            }
            if #available(iOSApplicationExtension 17.0, *) {
               ContactdWidget()
            }
            
        }
}

I had the same problem today. This is my solution

import WidgetKit
import SwiftUI

@main
struct WidgetLauncher {
    // Combine widgets in this way to prevent crashes.
    static func main() {
        if #available(iOSApplicationExtension 17.0, *) {
            WidgetsBundle17.main()
        } else {
            WidgetsBundle16.main()
        }
    }
}


struct WidgetsBundle16: WidgetBundle {
    var body: some Widget {
        SomeWidget()
    }
}

@available(iOSApplicationExtension 17.0, *)
struct WidgetsBundle17: WidgetBundle {
    var body: some Widget {
        SomeWidget()
        Only17Widget()
    }
}
