 | `maxPhotoQualityPrioritization` | `'balanced'` / `'quality'` / `'speed'` | [iOS 13 and newer](https://developer.apple.com/documentation/avfoundation/avcapturephotooutput/3182995-maxphotoqualityprioritization). `'speed'` provides a 60-80% median capture time reduction vs 'quality' setting. Tested on iPhone 6S Max (66% faster) and iPhone 15 Pro Max (76% faster!). Default `balanced`                                                                                                                                        |
 | `iOsSleepBeforeStarting`        | `number`                               | iOS only. Delay (ms) before the capture session starts. Default `100`. Set to `0` to skip. Helps ensure `session.commitConfiguration()` finishes before `session.startRunning()`, reducing occasional crashes seen when rapidly toggling cameras: `-[AVCaptureSession startRunning] startRunning may not be called between calls to beginConfiguration and commitConfiguration`. iOS feedback ID: FB21533559                                               |

Default `true`. When enabled, the first capture can be delayed by a few hundred milliseconds.
