# shouldAddStoreAsynchronously

A flag that determines whether the store is added asynchronously.

## Declaration

```swift
var shouldAddStoreAsynchronously: Bool { get set }
```

## Discussion

Discussion By default, the store is added to the NSPersistentStoreCoordinator synchronously on the calling thread. If this flag is set to true, the store is added asynchronously on a background queue. The default for this flag is false.
