I have an ShoppingItem Entity(attributes: name, id, unit, qty, description) and another entity ShoppingList(attributes: listDate, listName) and a relationship property : items which is many-to-many relationship.
The use case is :
_The items that are selected by the user have to be updated to the list on the particular date.
let myList = GroceryList(context: CoreDataManager.shared.viewContext)
myList.name = "One more List"
myList.madeOn = Date()
1. myList.mutableSetValue(forKey: "groceryItems").add(selectedGroceryItems)
CoreDataManager.shared.save()
selectedGroceryItems is of type
struct ItemEntityViewModel {
let groceryItem: GroceryItem
var itemEntityid: NSManagedObjectID {
return groceryItem.objectID
}
var id: UUID {
return groceryItem.id ?? UUID()
}
var name: String {
return groceryItem.name ?? ""
}
var category: String {
return groceryItem.category ?? "Not available"
}
var unit: String? {
return groceryItem.unit ?? ""
}
var qty: Double? {
return Double(groceryItem.qty)
}
}
line 1 throws exception as follows:
NSInvalidArgumentException', reason: -[Swift.__SwiftDeferredNSArray entity]: unrecognized selector sent to instance 0x600003f5e320' terminating with uncaught exception of type NSException
Hi,
I have downloaded the sample code for the Mapkit->Searching for Nearby Points of Interest. I wanted to know if there are guided project or Guides accompanied with the same.
Thanks in advance.
