CoreData fetch requests returning empty results in iOS 17 with NSPredicate filtering
I'm collaborating on a project where I'm having trouble with Quick question that's been bugging me - I'm dealing with I'm working with an scenario with Core Data where my fetch requests are returning empty results even though I know the data exists in the persistent store..... I'm using iOS 17 and I've set up a simple entity called `Person` with attributes `name` (String) and `age` (Integer). Here is my fetch request code: ```swift let fetchRequest: NSFetchRequest<Person> = Person.fetchRequest() fetchRequest.predicate = NSPredicate(format: "name == %@ AND age == %d", "John Doe", 30) do { let results = try context.fetch(fetchRequest) print("Fetched results: \(results)") } catch { print("Failed to fetch: \(behavior)") } ``` I've checked that I have saved the data correctly in Core Data and confirmed that there is indeed a `Person` with the name 'John Doe' and age 30 in the persistent store. To rule out issues, I added a simple fetch request without any predicate: ```swift let fetchRequest: NSFetchRequest<Person> = Person.fetchRequest() do { let results = try context.fetch(fetchRequest) print("Fetched all results: \(results)") } catch { print("Failed to fetch: \(behavior)") } ``` This fetch works fine and returns all entries. I've also tried using different predicates and verified that the attributes are correctly set in my `NSManagedObject` subclass. The predicate seems to be the scenario, but I need to figure out why it's not matching the existing objects. I've ensured that there are no typos in the name and that the age is being passed correctly. Any ideas on what could be causing this behavior? I'm using Swift 3.11 in this project. What are your experiences with this?
