# init(data:options:) Initializes a scene source for reading the scene graph contained in an `NSData` object. ``` init?(data: Data, options: [SCNSceneSource.LoadingOption : Any]? = nil) ``` ## Parameters `data` A data object containing a scene file in a format recognized by SceneKit. `options` A dictionary containing options that affect scene loading. See `Scene Loading Options` for available keys and values. Pass `nil` to use default options. ## Return Value An initialized scene source object, or `nil` if initialization was not successful. ## Discussion The `data` parameter of this method (an ) should contain the same data as directly read from a scene file (such as by using the method ). Use this method when you have the contents of a scene file but not the file itself—for example, if your app downloads scene files from the network. ## See Also [`sceneSourceWithURL:options:`](/documentation/SceneKit/SCNSceneSource/sceneSourceWithURL:options:) Creates a scene source that reads the scene graph from a specified file. [`sceneSourceWithData:options:`](/documentation/SceneKit/SCNSceneSource/sceneSourceWithData:options:) Creates a scene source that reads the scene graph contained in an `NSData` object. --- Copyright © 2026 Apple Inc.
