# loadModel(named:in:)

Synchronously loads a model entity from a bundle.

## Declaration

```swift
@MainActor @preconcurrency static func loadModel(named name: String, in bundle: Bundle? = nil) throws -> ModelEntity
```

## 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

Return Value The root entity in the loaded file, which Reality Kit casts as a ModelEntity.

## Discussion

Discussion Loading an Entity with this method blocks the main actor because it’s synchronous, so only call it from a command-line application. The method can stall a regular app, which makes it visibly hitch, and the system terminates an app if its UI becomes unresponsive. See init(named:in:) for an example that demonstrates how to safely load content.
