# obtainPermanentIDs(for:)

Returns an array containing the object IDs for a given array of newly-inserted objects.

## Declaration

```swift
func obtainPermanentIDs(for array: [NSManagedObject]) throws -> [NSManagedObjectID]
```

## Parameters

- `array`: An array of newly-inserted objects.

## Return Value

Return Value An array containing the object IDs for the objects in array.

## Discussion

Discussion The returned array must return the object IDs in the same order as the objects appear in array. Discussion This method is called before execute(_:with:) with a save request, to assign permanent IDs to newly-inserted objects.
