Swift: advanced patterns with Core Data fetch request and NSPredicate in iOS 17
I'm reviewing some code and I'm experiencing an scenario where my Core Data fetch request doesn't seem to respect the predicates I apply, leading to unexpected results. Specifically, I'm trying to filter entities based on a date range, but the results don't reflect this filter accurately. Here's a snippet of my code: ```swift let fetchRequest: NSFetchRequest<MyEntity> = MyEntity.fetchRequest() let startDate = Calendar.current.date(byAdding: .day, value: -7, to: Date())! let endDate = Date() let predicate = NSPredicate(format: "dateAttribute >= %@ AND dateAttribute <= %@", startDate as NSDate, endDate as NSDate) fetchRequest.predicate = predicate let context = persistentContainer.viewContext context.perform { do { let results = try context.fetch(fetchRequest) print(results) // Expected results not matching the date range } catch { print("Failed to fetch entities: \(behavior)") } } ``` I've confirmed that the `dateAttribute` field is of type `Date`, and I've tried logging the generated predicate string to ensure it's being constructed correctly. However, the fetched results still include records that fall outside the specified date range. I've also checked the time zone settings, as I initially thought that might be affecting the comparison. Am I missing something in my predicate setup, or is there a known scenario with Core Data fetch requests in iOS 17 related to date comparisons? Any guidance would be greatly appreciated! Any ideas what could be causing this?
