Initializer

init(sortDescriptors:predicate:animation:)

Creates a fetch request based on a predicate and reference type sort parameters.

Declaration 宣言 

init(sortDescriptors: [NSSortDescriptor], predicate: NSPredicate? = nil, animation: Animation? = nil)
Available when Result inherits NSManagedObject. ResultがNSManagedObjectを継承する場合に利用可能です。

Parameters パラメータ

sortDescriptors

An array of sort descriptors that define the sort order of the fetched results.

predicate

An NSPredicate instance that defines logical conditions used to filter the fetched results.

animation

The animation to use for user interface changes that result from changes to the fetched results.

Discussion 議論

The request gets the entity type from the Result instance by calling that managed object’s entity() type method. If you need to specify the entity type explicitly, use the init(entity:sortDescriptors:predicate:animation:) initializer instead. If you need more control over the fetch request configuration, use init(fetchRequest:animation:). For value type sort descriptors, use init(sortDescriptors:predicate:animation:).
