I am using Version 12.0.1 (12A7300). Widgets are added by size to the app being serviced, but only the medium size is shown. Below is the code. struct SRWidgetEntryView: View { @Environment(\.widgetFamily) private var widgetFamily var entry: Provider.Entry var body: some View { VStack { Text(entry.date, style: .time) switch widgetFamily { case .systemSmall: Text("systemSmall") case .systemMedium: Text("systemMedium") case .systemLarge: Text("systemLarge") @unknown default: Text("unknown") } } } } It works well when it comes to a new project, but why does this work in an existing app?

Thank you Gualtier Malde. Is it possible using the Bluetooth connection method in the link below? Thank you. https://developer.apple.com/documentation/corebluetooth/transferring_data_between_bluetooth_low_energy_devices
