# loadAsync(contentsOf:withName:) Returns a load request that creates an entity by asynchronously loading it from a file URL and preserving the entity’s hierarchy. ``` @MainActor @preconcurrency static func loadAsync(contentsOf url: URL, withName resourceName: String? = nil) -> LoadRequest ``` ## Parameters `url` A file URL representing the file to load. For Reality files, append a URL fragment to specify a scene name — for example, `my.reality#MyScene`. `resourceName` A unique name the method assigns to the resource it loads, for use in network synchronization. ## Discussion RealityKit supports loading entities from USD (`.usd`, `.usda`, `.usdc`, `.usdz`) and Reality (`.reality`) files. For Reality files that contain multiple scenes, specify which scene to load by appending a URL fragment with the scene name — for example, `my.reality#MyScene`.
