We are preparing to submit a new app that shares some functionality and with an app we have previously distributed on the App Store. The Codebase will be different (the existing one was developped using React JS and the Second one usinf SWIFT). While the new app includes updated features, a redesigned interface, and is intended for a different user audience, we would like to confirm in advance whether submitting it as a separate app (with a new Bundle ID) is acceptable under current App Store Review Guidelines.
In particular, we would appreciate clarification regarding Guideline 4.3 (Spam), to ensure that the submission will not be considered a duplicate or unnecessarily repetitive version of our existing app.
Could you please advise on this matter?
