Is it okay to publish an iOS app that won't work without an iCloud account?

Question

Does Apple frown upon apps that won't work without a valid iCloud account?

i.e. Can one use iCloud as the only authentication method in an iOS app that requires authentication?

Answer 1

I recently submitted an that does this and it was approved. I used iCloud and CloudKit for authentication and server. My initial viewController warns the user they must be logged into iCloud in order to use the app.
