Core Data’s NSFetchRequest supports bounding a query with an NSPredicate and limiting results with fetchLimit . Pagination is commonly implemented by advancing fetchOffset to skip previously fetched rows. With the SQLite store, the documented behavior is that the store still evaluates the full predicate and sort ordering before skipping rows, so execution ti
Implementing pagination for large datasets in Objective-C typically involves configuring an NSFetchRequest with fetchLimit and fetchOffset to retrieve specific data windows. To optimize memory usage, fetchBatchSize is often applied to prevent the immediate materialization of all objects in the result set. There is uncertainty regarding the execution order wh
Background Core Data’s NSFetchRequest exposes fetchLimit and fetchOffset for pagination. While these map to SQL LIMIT and OFFSET , they become inefficient on tables with thousands or millions of rows, especially when the underlying store is SQLite. The current APIs also lack a stable cursor mechanism, so changing data between paged requests can lead to dupli
