So far in this chapter we have looked at adding a single gesture recognizer to a view in SwiftUI. Though a less common requirement, it is also possible to combine multiple gestures and apply them to a view. Gestures can be combined so that they are detected simultaneously, in sequence or exclusively. When gestures are composed simultaneously, both gestures must be detected at the same time for the corresponding action to be performed.
