Yes, these are different design paradigms see the focus example for when there is a change in data and how this is used to trigger a UI element focus under accessibility. https://developer.apple.com/documentation/swiftui/creating_accessible_views/

Please post your question on the unity developer forums over at unity.

No one has had this issue because Apps are implemented on the watch with the watch version of the iOS UI and functionality. There are no shortcuts.

Any reason why you're running something no longer supported and expect it to work still?

Just use Xcode

Because certItem is nil hence the crash on force unwrap.

Your code modified to use a TextField instead of a Text view. import SwiftUI struct ContentView: View {     @FocusState private var focusedItem: Optional<FocusedItem>     @State var inputname: String = ""          var body: some View {         VStack {                          TextField("Test", text: $inputname)             #if os(macOS)                 .focusable(true)             #endif                 .focused($focusedItem, equals: .two)             Button("Toggle Focus") {                 self.focusedItem=(self.focusedItem == nil) ? .two : nil             }.onChange(of: focusedItem) { newValue in                 // Always prints `nil`.                 print(newValue as Any)             }         }     }          enum FocusedItem: Equatable {         case one, two         func other() -> FocusedItem {             switch self {             case .one: return .two             case .two: return .one             }         }     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView()     } }

Using a Text view is not supported with focus. Focus is used for setting the input focus (firstResponder) for input-oriented controls like TextField, TextEditor etc. Read the documentation first, it usually helps.

Just because the path is correct doesn't mean you have permission to access it.

What do you want to reboot? The phone? Not Possible The App? Possible but pointless

The dreams and aspirations

Move all of your core data operations into its own class. Take a look at the food truck example code. View-only code should exist only in the view.

Threading 101 - You are doing too much work on the main thread.

The foregroundColor in attributes doesn't take a cgColor context.cgContext.setFillColor(UIColor.black.cgColor) not needed use UIColor.black.setFill() instead. Final changes let imageSize = CGSize(width: 400, height: 100) let testRenderer = UIGraphicsImageRenderer(size: imageSize) let testImage = testRenderer.image { context in     UIColor.black.setFill()     context.fill(CGRect(origin: .zero, size: imageSize))     let paragraphStyle = NSMutableParagraphStyle()     paragraphStyle.alignment = .left     let attributes: [NSAttributedString.Key: Any] = [         .font: UIFont.systemFont(ofSize: 8.0),         .paragraphStyle: paragraphStyle,         .foregroundColor: UIColor.white]     var attributedString = NSAttributedString(string: "This is some text",                                               attributes: attributes)     let drawContext = NSStringDrawingContext()     drawContext.minimumScaleFactor = 0.5     attributedString.draw(with: testRenderer.format.bounds, options: .usesLineFragmentOrigin,                           context: drawContext) } -enjoy!
