## How to use Xcode 26 beta

To use Xcode 26 beta to create your builds, specify the following image in your **eas.json**:

```json
{
  "build": {
    "preview": {
      "ios": {
        "image": "macos-sequoia-15.5-xcode-26.0"
      }
    }
  }
}
```

For Workflows, specify the image in your job configuration:

```yaml
jobs:
  build:
    type: build
    image: macos-sequoia-15.5-xcode-26.0
    params:
      platform: ios
```

As new beta images roll out, we'll continue to update our xcode image under this image name, so you'll always have the latest.

## Testing before public release

Using this beta image allows you to test your app against the latest iOS 26 SDK and identify any compatibility issues before the public release later this fall. For a complete list of supported build images, see our [infrastructure documentation](https://docs.expo.dev/build-reference/infrastructure/#ios-build-server-configurations).
