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'm writing code to get a remote image via URL and I get the following error each time. I converted the URL to https as recommended.
This is the error I get.
URL is Optional(https://img.recipepuppy.com/627470.jpg)

The code I use is:
print("URL is \(String(describing: self.thumbNailUrl))")
DispatchQueue.global().async { [weak self] in
if let data = try? Data(contentsOf: self!.thumbNailUrl!) {
if let image = UIImage(data: data) {
DispatchQueue.main.async {
self?.imageView.image = image
}
}
}
}
Any suggestions?

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'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
