# NotificationCenter.Notifications

An asynchronous sequence of notifications generated by a notification center.

## Declaration

```swift
final class Notifications
```

## Overview

Overview Use the notifications(named:object:) method to create an instance of this type, then iterate over its elements with the for-await-in syntax. tip: The Notification type doesn’t conform to Sendable, so iterating over this asynchronous sequence produces a compiler warning. You can use a map(_:) or compactMap(_:) operator on the sequence to extract sendable properties of the notification and iterate over those instead. See notifications(named:object:) for an example of this approach.
