Core Data Fetch Request Results in Incomplete Data on iOS 17 with SwiftUI
Could someone explain I've hit a wall trying to I'm working with an scenario with a Core Data fetch request in my SwiftUI application that seems to be returning incomplete data. My setup involves a simple entity called `Item` with attributes `name` (String) and `quantity` (Int). When I execute the fetch request in my `View`, I notice that sometimes the `Item` instances do not show up in my list even though they exist in the datastore. For example, if I have three `Item` entries in my database, `fetchRequest.fetchLimit` set to 10, I expect all three to appear but only one or two show up intermittently. Here’s the code for my fetch request: ```swift @FetchRequest(sortDescriptors: [SortDescriptor("name")]) var items: FetchedResults<Item> ``` I’ve also tried adding a predicate to ensure I'm filtering correctly, but that didn't resolve the question: ```swift @FetchRequest(sortDescriptors: [SortDescriptor("name")], predicate: NSPredicate(format: "quantity > %d", 0)) var items: FetchedResults<Item> ``` Despite the predicates, if I perform a manual fetch using `NSFetchRequest<Item>(entity: Item.entity(), context: viewContext)` and log the results, they appear as expected. The question seems to lie with the way the `FetchRequest` is configured in my SwiftUI view. I've tried reloading the view by updating the `viewContext` without success. Additionally, I’m seeing a warning in the console that says `CoreData: warning: Failed to call designated initializer on NSPersistentContainer`. I’m not sure if that’s related to my scenario or just a benign warning. Could anyone provide insight into what might be causing this incomplete data scenario, especially with the potential console warning on iOS 17? Any advice on best practices for using `FetchRequest` in SwiftUI would also be appreciated. I'm coming from a different tech stack and learning Swift. Any pointers in the right direction? Any help would be greatly appreciated!
