I have an old app in the store that was written in Objective-C. I would like to rewrite the app completely in SwiftUI and just have it be a update to the app in the store. How do I do this?
Apps are uniquely tagged by the Bundle Identifier - for example com.mycompany.testapp
If you want to rewrite your app, start a new project/workspace and enter the same bundle id used on your existing app in the store. Then when uploading it to App Store Connect, the backend system will see the new binary as a replacement for the old one.
