I need a Swift function to obtain the Magic Mouse battery level. I am working on an app to display the battery level in the Status Bar. I have the Status Bar code working. Functions for the Wireless keyboard and Track Pad would also be helpful.

Can someone translate this: Details SendProcessControlEvent:toPid: encountered an error: Error Domain=com.apple.dt.deviceprocesscontrolservice Code=8 "Failed to show Widget 'com.just.Memory-Widget.Free-Memory' error: Error Domain=FBSOpenApplicationServiceErrorDomain Code=1 "The request to open "com.apple.springboard" failed."

Xcode 14.1, iOS 16.1, MacOS 12.5, Working on a Lock Screen widget with home screen widget. This code: struct Battery_LevelEntryView : View { @Environment(\.widgetFamily) var widgetFamily     var entry: Provider.Entry     var body: some View { switch widgetFamily{ case .systemSmall: ... case ... : If I include the .systemSmall case, each time I run the app on the iPhone, it adds an additional home screen widget, rather than replacing the first home screen widget.

I am creating a widget using WidgetKit to display the iPhone battery level. I setup the following timeline to update the widget very minute. (I use one minute for testing the app. Once it works I'll use five minutes to preserve resources.) In the "View" I display the time and battery level. The time is updated every minute. However, the battery level does not get updated. func getTimeline(in context: Context, completion: @escaping (Timeline) -> ()) { var entries: [SimpleEntry] = [] let currentDate = Date() let updateInterval = 1 for minuteOffset in stride(from: 0, to: 60, by: updateInterval ) { let entryDate = Calendar.current.date( byAdding: .minute, value: minuteOffset, to: currentDate )! let entry = SimpleEntry( date: entryDate ) entries.append(entry) } let timeline = Timeline(entries: entries, policy: .atEnd) completion(timeline) } // func var body: some View { let _ = UIDevice.current.isBatteryMonitoringEnabled = true let batteryLevel = UIDevice.current.batteryLevel VStack { Text(entry.date, style: .time) let str = String( format: "%.0f%%", batteryLevel * 100.0 ) Text( str ) } } // some View

When I print a UIImage using AirPrint, the image is scaled to fill the page (8.5 x 11 ). How can I scale the image to a smaller size?
