How to fix TINT mode easily since it is iOS 18

To set up iOS 18 widget tint mode without any modifications, follow the steps below.

I hope this helps many people.

You just need to add one line.

.containerBackgroundRemovable(false)

ex)

struct create_view: Widget {
    let kind: String = "CalendarWidget"


    var body: some WidgetConfiguration {
        StaticConfiguration(kind: kind, provider: Provider()) { entry in
            calendar_widgetEntryView(entry:  entry)
        }
      
        .supportedFamilies([.systemLarge])
        .containerBackgroundRemovable(false)
        .contentMarginsDisabledIfAvailable()
    }
}
