# init(data:options:)

Initializes a scene source for reading the scene graph contained in an NSData object.

## Declaration

```swift
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

Return Value An initialized scene source object, or nil if initialization was not successful.

## Discussion

Discussion The data parameter of this method (an NSData) should contain the same data as directly read from a scene file (such as by using the NSData method doc://com.apple.documentation/documentation/foundation/nsdata/init(contentsofurl:)-6foqd). 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.
