# DeviceActivitySchedule

A calendar-based schedule for when to monitor a device’s activity.

```
struct DeviceActivitySchedule
```

## Overview

Create a new schedule using `DateComponents` that allows your app to monitor the person’s device activity during a period of time.
You can set a schedule for your app to monitor on a regularly occuring basis.
You can create a warning time that the system uses to provide your app extension with
callbacks whenever a schedule is about to start or end, or when an event is close to reaching its threshold.
