# PHASEEngine.UpdateMode

Modes that determine when the framework consumes API calls and updates internal state.

```
enum UpdateMode
```

## Overview

To define the manner in which PHASE processes commands and updates internal state, select an option from this enumeration and pass it to the `updateMode` parameter of the [`PHASEEngine`](/documentation/PHASE/PHASEEngine) initializer, [`init(updateMode:)`](/documentation/PHASE/PHASEEngine/init(updateMode:)).

## Topics

### Modes

[`PHASEEngine.UpdateMode.manual`](/documentation/PHASE/PHASEEngine/UpdateMode/manual)
