# loadAsync(named:in:) Returns a load request that creates an entity by asynchronously loading it from a bundle. ``` @MainActor @preconcurrency static func loadAsync(named name: String, in bundle: Bundle? = nil) -> LoadRequest ``` ## Parameters `name` The base name of the file to load, omitting the filename extension. `bundle` The bundle containing the file. Use `nil` to search the app’s main bundle. ## Return Value A resource loader that publishes the root entity in the loaded file. ## Discussion RealityKit supports loading entities from USD (`.usd`, `.usda`, `.usdc`, `.usdz`) and Reality (`.reality`) files. When building your app, Xcode automatically converts any Reality Composer projects (`.rcproject`) in the selected target into Reality files, which it then copies into your app’s bundle.
