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

Question

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()
            }
            
        }
}
