Guideline 4.3 is the rejection for an app that looks like one Apple already has: a second bundle ID for the same product, a per-customer or per-region copy, or an app that is indistinguishable from a template. For a Rails team it usually means a staging app, a white-label build, or a second app for a second brand. The fix is one app, with the variation inside it.
From the App Store Review Guidelines, 4.3(a):
Don't create multiple Bundle IDs of the same app (for example, submitting a separate map app for every city in the world instead of a single worldwide map that allows users to search any city). This practice results in unnecessary apps, which makes it hard for users to find the apps they want. If your app has different versions for specific locations, sports teams, universities, etc., consider submitting a single app and providing the variations using in-app purchase.
And 4.3(b):
Don't submit apps that are indistinguishable from what's already widely available.
In substance: the app duplicates the content and functionality of another app submitted by you or another developer, or it is one of many similar apps, and Apple asks you to combine them or to differentiate it. Sometimes the reviewer names the other app.
Three ways. A staging app was submitted to the store instead of kept on TestFlight. A multi-tenant product shipped one app per customer, each with the customer's name and icon on the same codebase. Or a second brand on the same Rails app got its own bundle ID and its own listing. Related: guideline 4.2.6 says apps created from a commercialized template or app generation service will be rejected unless they are submitted directly by the provider of the app's content, which is why Ruby Native builds run under your own developer account and never from ours.
ruby_native withdraw or from the dashboard, and say so.If the two apps are different products:
Thank you for the review. [App A] and [App B] are separate products for different users: [A] is [what and for whom], [B] is [what and for whom]. They share no content and no accounts, and each has its own [screens/features]. We've attached screenshots of both first screens to show the difference. We'd appreciate a second look under 4.3.
From Joe: TODO one line on what actually got an app through 4.3.
With the launch review, send the rejection to Joe from your dashboard. He replies within two business days with the reply to send, or the change to make before resubmitting.
