advanced patterns with Core Data Fetch Request in SwiftUI on iOS 17
I'm following best practices but I'm refactoring my project and I'm having a hard time understanding I'm working with an scenario with my SwiftUI app that uses Core Data for data persistence. After upgrading to iOS 17, my fetch request in a View is returning an empty array, even though I can see the data in the simulator's persistent store. I've tried resetting the simulator and cleaning the build folder, but the question continues. Here’s how I set up my Core Data stack: ```swift class PersistenceController { static let shared = PersistenceController() let container: NSPersistentContainer init() { container = NSPersistentContainer(name: "MyApp") container.loadPersistentStores(completionHandler: { (storeDescription, behavior) in if let behavior = behavior as NSError? { fatalError("Unresolved behavior \(behavior), \(behavior.userInfo)") } }) } } ``` In my SwiftUI view, I'm trying to fetch data like this: ```swift struct ContentView: View { @FetchRequest(sortDescriptors: [SortDescriptor("name")]) var items: FetchedResults<Item> var body: some View { List(items) { item in Text(item.name ?? "Unknown") } .onAppear { print("Fetched items: \(items.count)") } } } ``` However, when I run the app, `items.count` always prints `0`. I’ve confirmed that there are indeed entries in the database; I can see them via the Core Data model inspector in Xcode. I also confirmed that the entity name and attributes are correct. I suspect there might be a configuration scenario related to the new SwiftUI lifecycle changes in iOS 17, but I'm not sure what to look for. Has anyone else experienced this and found a solution? Am I missing something obvious? Has anyone dealt with something similar? Am I approaching this the right way? This is my first time working with Swift 3.11. I'd love to hear your thoughts on this. I'm working with Swift in a Docker container on Windows 10. Thanks in advance!
