# isTemporaryID

A Boolean value that indicates whether the object ID is temporary.

## Declaration

```swift
var isTemporaryID: Bool { get }
```

## Discussion

Discussion true if the receiver is temporary, otherwise false. Most object IDs return false. New objects inserted into a managed object context are assigned a temporary ID which is replaced with a permanent one once the object gets saved to a persistent store.
