# init(predicate:sortBy:) Creates a fetch descriptor with the specified predicate that, optionally, arranges the fetched models in a particular order. ``` init(predicate: Predicate? = nil, sortBy: [SortDescriptor] = []) ``` ## Parameters `predicate` The logical condition that determines whether the fetch includes a specific model in its results. The default value is `nil`. `sortBy` The array of sort descriptors that tell the fetch how to order its results. The default value is an empty array. ## Discussion If you don’t specify a predicate, any fetch using this descriptor will return all models of the associated type. If you expect the number of fetched models to be high, use [`fetchLimit`](/documentation/SwiftData/FetchDescriptor/fetchLimit) and [`fetchOffset`](/documentation/SwiftData/FetchDescriptor/fetchOffset) to break those results into smaller, more efficient batches. --- Copyright © 2026 Apple Inc.
