# UIHingeInteraction

An interaction for observing the hinge state associated with the view’s hierarchy.

## Declaration

```swift
@MainActor class UIHingeInteraction
```

## Overview

Overview Add a UIHingeInteraction to a view to receive hinge state updates. The interaction’s handler is called when the hinge state changes, or when the interaction moves between hierarchies. When the interaction moves out of a hierarchy that provides hinge updates, the update’s hinge is nil. override func viewDidLoad() {     super.viewDidLoad()

let interaction = UIHingeInteraction { [weak self] _, update in         guard let self else { return }         // A nil `hinge` indicates the interaction has left a         // hierarchy that provides hinge updates.         guard let hinge = update.hinge else {             handleHingeUnavailable()             return         }

updateAngleDisplay(with: hinge.angle)         updateStatusDisplay(with: hinge.status)     }

view.addInteraction(interaction) } In the example above, the current angle and status of the hinge are displayed as the user interacts with the hinge.
