Can a Default Messaging App Handle Legacy SMS Messages on iOS

I have been reviewing the documentation on preparing your app to be the default messaging app, and I am wondering about the following:

  1. If I set my app as the default messaging app, will it be able to send and receive legacy SMS messages?

  2. Does iOS provide any SMS-specific framework or APIs to facilitate handling SMS messages directly within my app?

I’d appreciate any clarification on whether iOS supports such functionality and, if so, how to integrate it into my app.

Thank you!
