should i use sirikit payments domain or app intents for banking app

For a banking app, you should consider using App Intents if your app does not overlap with an existing SiriKit domain. App Intents is the right framework for integrating your app with Siri, especially if there isn't a specific SiriKit domain that fits your app's functionality. This framework allows you to integrate with Siri, Shortcuts, Spotlight, and more, providing a flexible way to enhance user interaction with your app.

If your app's functionality aligns with an existing SiriKit domain, then SiriKit might be the better choice. However, for most banking apps, App Intents would likely be the appropriate framework to use, as it allows for a broader range of custom actions and integration points.
