Hi,
I have added widgets to my iOS app and I would like to make this feature only accessible to "pro" users that have made a non-consumable in-app purchase.
Currently, I am doing the following: I store an "isUnlocked" property in the Keychain after the purchase is made
I read data to be displayed in the widget and here I also query the Keychain and store whether the widget is unlocked
I have no refresh policy, but only change the widget data on a significant time change
a different view is displayed when the app is locked
Some dummy code snippets:
func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> Void) {
		let entry = readContents()
		let timeline = Timeline(entries: [entry], policy: .never)
		completion(timeline)
}
struct WidgetEntryView: View {
		let entry: Provider.Entry
@Environment(\.widgetFamily) var family
@ViewBuilder
var body: some View {
switch family {
case .systemSmall:
if !entry.isUnlocked {
LockedWidgetView()
} else if let event = entry.event {
SmallWidgetEventView(event: event)
} else {
NoDataWidgetView()
}
...
func applicationSignificantTimeChange(_ application: UIApplication) {
		if #available(iOS 14.0, *) {
				WidgetCenter.shared.reloadAllTimelines()
		}
...
However, 2 unexpected things happen: the view is refreshed intraday (not only at midnight i.e. at significant time change)
sometimes the LockedWidgetView is displayed.
Especially the latter is problematic, because it gives false information to a user that has already made the in-app purchase.
How can I achieve my goal of only displaying info when the user has made the in-app purchase?
Thanks in advance.
P.S. Although it would not have my preference, I would also find it acceptable if the widget is only shown as option to add once the purchase is made. In other words, I was considering changing the Widget itself:
struct MyWidget: Widget {
private var supportedFamilies: [WidgetFamily] = isUnlocked() ? [.systemSmall, .systemMedium] : []
but I believe I cannot re-initialise the widget from the app when the user makes the in-app purchase, because the only refresh option that I have is
WidgetCenter.shared.reloadAllTimelines()
