Instance Method

objects(at:)

Returns an array containing the objects in the fetch result at the indexes in the specified index set.

Declaration

func objects(at indexes: IndexSet) -> [ObjectType]

Parameters

indexes

An index set containing indexes within the bounds of the fetch result.

Return Value

An array containing the objects in the fetch result at the indexes specified by indexes.

Discussion

The ordering of the returned array follows the index set. That is, in the returned array, an object with a higher index in the index set comes after any object with a smaller index in the index set.

Raises an exception (rangeException) if any index in the index set is beyond the end of the fetch result (that is, greater than or equal to the value of the count property).
