The current version of the app was made on xcode but the guy who developed it left us and and didn't leave the source code. So we made a new version from the ground-up using Xamarin. Now we want to publish it. Should it just be an update for the current version or should we make a another app in appstoreconnect and delete the current version?
App on appstore was made using xcode but upcoming version was made using xamarin, are there problems?
Do you keep the exact same appstore references for the app ? And is it the same developer account that will submit the app. Otherwise it will be considered a different one. And if too close in functionality, may be seen as a Spam.
