This is not something Airtable will be able to do natively, but since you are using iPhone, you could try using the Shortcuts app to create a shortcut that hits the Airtable API, pulls contact data, and then adds it to your Contacts app. I can’t provide any further assistance in writing the actual shortcut, just letting you know that this may be something that is possible since the Shortcuts app is capable of working with API’s, and Airtable provides an API for retrieving data.
