# presentationContext The context describing where your iMessage app is presented. ``` var presentationContext: MSMessagesAppPresentationContext { get } ``` ## Discussion By default, the system only displays iMessage apps in the [`MSMessagesAppPresentationContext.messages`](/documentation/Messages/MSMessagesAppPresentationContext/messages) context (the iMessage app only appears inside the Messages app). iMessage apps in the media context have additional limitations and design considerations. You can control the supported contexts by adding the `MSSupportedPresentationContexts` key to the iMessage app extension’s `Info.plist` file. For example, [`presentationContext`](/documentation/Messages/MSMessagesAppViewController/presentationContext) enables the iMessage app in effects in Messages and FaceTime. ```plist MSSupportedPresentationContexts MSMessagesAppPresentationContextMessages MSMessagesAppPresentationContextMedia ``` --- Copyright © 2026 Apple Inc.
