Type Method


Loads a scene from the specified URL.


+ (instancetype)sceneWithURL:(NSURL *)url options:(NSDictionary<SCNSceneSourceLoadingOption, id> *)options error:(NSError * _Nullable *)error;



The URL to the scene file to load.


A dictionary of options affecting scene loading, or nil for default options. For available keys, see Scene Loading Options.


If an error occurs, this pointer is set to an NSError object describing the error. If you do not want error information, pass in nil.

Return Value

A new scene object, or nil if no scene could be loaded.


This method provides a convenient way to load a complete scene from a file at an arbitrary URL. For more detailed options or to load only part of a file’s scene graph, use the SCNSceneSource class.

When creating a scene using Xcode's Scene Editor or an external tool, you should copy your scene file into a directory with the .scnassets extension inside your app bundle. You should also place any image files referenced as textures from that scene in an Asset Catalog. Xcode will optimize the scene and texture resources for best performance on each target device, and prepare your texture resources for delivery features such as App Thinning and On-Demand Resources.
