# ProcessInfo.ActivityOptions

Option flags used with [`beginActivity(options:reason:)`](/documentation/Foundation/ProcessInfo/beginActivity(options:reason:)) and [`performActivity(options:reason:using:)`](/documentation/Foundation/ProcessInfo/performActivity(options:reason:using:)).

```
struct ActivityOptions
```

## Overview

To include one of these individual flags in one of the sets, use bitwise `OR`; for example, during a presentation you might use:

```objc
NSActivityUserInitiated | NSActivityIdleDisplaySleepDisabled
```

To exclude from one of the sets, use bitwise `AND` with `NOT`; for example, during a user initiated action that may be safely terminated with no application interaction in case of logout you might use:

```objc
NSActivityUserInitiated & ~NSActivitySuddenTerminationDisabled
```
