Topics

Creating an Exclusive Gesture

init(First, Second)

Creates a gesture from two gestures where only one of them succeeds.

var first: First

The first of two gestures.

var second: Second

The second of two gestures.

typealias ExclusiveGesture.Body

A type that represents the exclusive gesture and its behavior.

Performing the Gesture

enum ExclusiveGesture.Value

The value of an exclusive gesture that indicates which of two gestures succeeded.

Composing Gestures

func simultaneously<Other>(with: Other) -> SimultaneousGesture<ExclusiveGesture<First, Second>, Other>

Combines a gesture with another gesture to create a new gesture that recognizes both gestures at the same time.

func sequenced<Other>(before: Other) -> SequenceGesture<ExclusiveGesture<First, Second>, Other>

Sequences a gesture with another one to create a new gesture, which results in the second gesture only receiving events after the first gesture succeeds.

func exclusively<Other>(before: Other) -> ExclusiveGesture<ExclusiveGesture<First, Second>, Other>

Combines two gestures exclusively to create a new gesture where only one gesture succeeds, giving precedence to the first gesture.

Transforming a Gesture
