# cubeMap(withContentsOfFiles:options:queue:completionHandler:) Asynchronously loads a cube map texture image from a series of files and creates a new texture from the data. ``` func cubeMap(withContentsOfFiles paths: [Any], options: [String : NSNumber]? = nil, queue: dispatch_queue_t?, completionHandler block: @escaping @Sendable (GLKTextureInfo?, (any Error)?) -> Void) ``` ## Parameters `paths` An array of paths to the six files that make up the cube map. `options` A dictionary that describes any additional steps you want the texture loader to take when loading the texture. See [Texture Loading Options](/documentation/GLKit/texture-loading-options). `queue` A dispatch queue that your block is called on when the task completes. If `NULL` is passed, the block is called on the main dispatch queue. `block` A block to be called when the task completes. ## Discussion This method is identical to [`cubeMap(withContentsOf:options:)`](/documentation/GLKit/GLKTextureLoader/cubeMap(withContentsOf:options:)), except that it loads the texture asynchronously. When this method is called, it creates a new background task to handle the request and then returns control to your app. Later, when the task is complete, GLKit calls your completion handler on the queue you provided. --- Copyright © 2026 Apple Inc.
