| Artifact | Description | Supported Platforms |
|-|-|-|
| onnxruntime-mobile-objc | CPU and CoreML | iOS |

Refer to the [installation instructions](../../how-to/mobile/initial-setup.md#iOS).

## Swift Usage

The Objective-C API can be called from Swift code.
To enable this, use a bridging header (more info [here](https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_objective-c_into_swift)) that imports the ORT Objective-C API header.

```objectivec
// In the bridging header, import the ORT Objective-C API header.
#import <onnxruntime.h>
```
