Hi, I'm new to iOS development. I'm trying to set User Defined Runtime Attributes to a button and getting the Key path as "music.key" as String. I then try to get the value using the code below in the ViewCOntroller. print(sender.value(forKeyPath: "music.key")!) I get the error 2020-10-06 12:05:11.519925+1100 Xylophone[81797:29787109] Failed to set (music.key) user defined inspected property on (UIButton): [<UIButton 0x7fe1ffc0c410> valueForUndefinedKey:]: this class is not key value coding-compliant for the key music. What am I doing wrong? Is there a page on how to properly use User Defined Runtime Attributes? Much Appreciated. Thanks

Hi, Anyone encountered this? I bring up a modal sheet using my add button. Then I dismiss it by swiping down. Immediately after that, the button is unresponsive and I cannot bring up the modal sheet again. However, if I scroll the list, the button is functional again. I can include a video of what I see if you like. Snippet of my code below. struct TaskToDoView: View {     @Environment(\.managedObjectContext) private var viewContext     @FetchRequest(         sortDescriptors: [NSSortDescriptor(keyPath: \SimpleRecord.title, ascending: true)],         animation: .default)     private var items: FetchedResults<SimpleRecord>     @State private var isModal = false          var body: some View {         NavigationView {             List {                 ForEach(items) { item in                     NavigationLink(destination: ToDoModelView()) {                         Text("Item at \(item.title!)")                     }                                      }                 .onDelete(perform: deleteItems)             }             .toolbar {                 HStack {                     #if os(iOS)                     EditButton()                     #endif                      Button(action: addItem) {                         Label("Add Item", systemImage: "plus")                     }                     .sheet(isPresented: $isModal,                             onDismiss: dismissToDoModelView,                             content: {                         ToDoModelView()                     })                 }             }         }     }     private func dismissToDoModelView() {         print("Modal Dismissed")         print("Modal is \(self.isModal)")     }     private func addItem() {         self.isModal.toggle()     } .... }

Hi, I wish to remotely load some data before I initialise the collection view. I read somewhere one way to do this is to only set the delegate and datasource after I loaded the data. However I'm setting the error "UICollectionView.delegate must be used from main thread only" next to the line self.myCollectionView.delegate = self I suppose this is not the best way to do this. What is the recommended way? Cheers Richard

Hi, I'd like to use a MLX model already in the MLX Community in my App. I understand I first need to convert it to Core ML format. Is there an easy way to do that considering MLX is an Apple project? It would be good if it was easier then I'd be more motivated to use MLX to train my models. Thanks Richard
