# AppKit integration Add AppKit views to your SwiftUI app, or use SwiftUI views in your AppKit app. ## Overview Integrate SwiftUI with your app’s existing content using hosting controllers to add SwiftUI views into AppKit interfaces. A hosting controller wraps a set of SwiftUI views in a form that you can then add to your storyboard-based app.  You can also add AppKit views and view controllers to your SwiftUI interfaces. A representable object wraps the designated view or view controller, and facilitates communication between the wrapped object and your SwiftUI views. For design guidance, see in the Human Interface Guidelines. ## Topics ### Displaying SwiftUI views in AppKit [Unifying your app’s animations](/documentation/SwiftUI/Unifying-your-app-s-animations) Create a consistent UI animation experience across SwiftUI, UIKit, and AppKit. [`NSHostingController`](/documentation/SwiftUI/NSHostingController) An AppKit view controller that hosts SwiftUI view hierarchy. [`NSHostingView`](/documentation/SwiftUI/NSHostingView) An AppKit view that hosts a SwiftUI view hierarchy. [`NSHostingMenu`](/documentation/SwiftUI/NSHostingMenu) An AppKit menu with menu items that are defined by a SwiftUI View. [`NSHostingSizingOptions`](/documentation/SwiftUI/NSHostingSizingOptions) Options for how hosting views and controllers reflect their content’s size into Auto Layout constraints. [`NSHostingSceneRepresentation`](/documentation/SwiftUI/NSHostingSceneRepresentation) An AppKit type that hosts and can present SwiftUI scenes [`NSHostingSceneBridgingOptions`](/documentation/SwiftUI/NSHostingSceneBridgingOptions) Options for how hosting views and controllers manage aspects of the associated window. ### Adding AppKit views to SwiftUI view hierarchies [`NSViewRepresentable`](/documentation/SwiftUI/NSViewRepresentable) A wrapper that you use to integrate an AppKit view into your SwiftUI view hierarchy. [`NSViewRepresentableContext`](/documentation/SwiftUI/NSViewRepresentableContext) Contextual information about the state of the system that you use to create and update your AppKit view. [`NSViewControllerRepresentable`](/documentation/SwiftUI/NSViewControllerRepresentable) A wrapper that you use to integrate an AppKit view controller into your SwiftUI interface. [`NSViewControllerRepresentableContext`](/documentation/SwiftUI/NSViewControllerRepresentableContext) Contextual information about the state of the system that you use to create and update your AppKit view controller. ### Adding AppKit gesture recognizers into SwiftUI view hierarchies [`NSGestureRecognizerRepresentable`](/documentation/SwiftUI/NSGestureRecognizerRepresentable) A wrapper for an `NSGestureRecognizer` that you use to integrate that gesture recognizer into your SwiftUI hierarchy. [`NSGestureRecognizerRepresentableContext`](/documentation/SwiftUI/NSGestureRecognizerRepresentableContext) Contextual information about the state of the system that you use to create and update a represented gesture recognizer. [`NSGestureRecognizerRepresentableCoordinateSpaceConverter`](/documentation/SwiftUI/NSGestureRecognizerRepresentableCoordinateSpaceConverter) A structure used to convert locations to and from coordinate spaces in the hierarchy of the SwiftUI view associated with an [`NSGestureRecognizerRepresentable`](/documentation/SwiftUI/NSGestureRecognizerRepresentable). --- Copyright © 2026 Apple Inc.
