# API Notes: SpriteKit framework

The full API is described in Apple’s documentation, both the C and Objective-C APIs are available (but see the API Notes below).

These bindings are accessed through the `SpriteKit` package (that is, `import SpriteKit`).

## API Notes

- `SK_VERSION`: This constant is not exposed as it changes with the SDK used.

- `+[SKFieldNode customFieldWithEvaluationBlock:]`

  This method is not supported yet (requires changes to the core bridge)

Note

This framework is only available on macOS 10.9 and later.
