Requiring sign is a deal breaker for me as well. What happens is that a year from now I may want to use your application but will inevitably be on a new/different device and will have forgotten the email and password I used to create the account. Why add friction when it is obviously not necessary. Using the app without an email should be a primary workflow. Adding a temporary “try offline” mode is insufficient imo. That being said if you have to require sign in Sign in with Apple is definitely the way to go.
