# NSTouch.Phase

The possible phases of a touch.

```
struct Phase
```

## Overview

These constants are used by [`phase`](/documentation/AppKit/NSTouch/phase-swift.property).

## Topics

### Creating a Touch Phase

[`init(rawValue:)`](/documentation/AppKit/NSTouch/Phase-swift.struct/init(rawValue:))

Creates a new touch phase from the given raw value.

### Constants

[`began`](/documentation/AppKit/NSTouch/Phase-swift.struct/began)

A finger touched the device. Or, a resting touch transitioned to an active touch and resting touches are not wanted by the view hierarchy.

[`moved`](/documentation/AppKit/NSTouch/Phase-swift.struct/moved)

A finger moved on the device.

[`stationary`](/documentation/AppKit/NSTouch/Phase-swift.struct/stationary)

A finger is touching the device, but hasn’t moved since the previous event.

[`ended`](/documentation/AppKit/NSTouch/Phase-swift.struct/ended)

A finger was lifted from the screen. Or, an active touch transitioned to a resting touch and resting touches are not wanted by the view hierarchy.

[`cancelled`](/documentation/AppKit/NSTouch/Phase-swift.struct/cancelled)

The system cancelled tracking for the touch, as when (for example) the window associated with the touch resigns key or is deactivated.

[`touching`](/documentation/AppKit/NSTouch/Phase-swift.struct/touching)

Matches the [`began`](/documentation/AppKit/NSTouch/Phase-swift.struct/began), [`moved`](/documentation/AppKit/NSTouch/Phase-swift.struct/moved), or [`stationary`](/documentation/AppKit/NSTouch/Phase-swift.struct/stationary) phases of a touch.

[`any`](/documentation/AppKit/NSTouch/Phase-swift.struct/any)

Matches any phase of a touch.
