A segue is a connection that represents a transition from one scene to another scene, such as one scene sliding over another. The connection is between an object in one scene that a user touches to initiate the transition, and a scene or a storyboard reference that is the target of the transition.
On the storyboard, segues appear as an arrow between scenes. The arrow includes a symbol for the type of segue. The screenshot shows a push segue.
There are several types of segues, some of which are unique to either macOS or iOS. The following two tables list the types of segue for each platform, including the name, Interface Builder symbol, and a brief description.
