Sorry but that's their problem. Cat Daddy released an update for all Operating Systems. And from their side, this update was available immediately.
Now, if Apple wants to spend 1-2-3-5 days to test, evaluate and approve the app, that's
THEIR problem. It is not Cat Daddy's or Android users fault that one company has these security/quality control issues. And it's not CD's obligation to make some "special arrangements" just for Apple. CD just publishes a multiplatform game and gives it to everyone. What and how Apple decides to handle it, is entirely up to Apple and noone else can (nor should) be held accountable for that. That is the Apple policy and they should be the ones to have to deal with it.
iOS users should wait while the other users played. And IF those iOS users had a problem with that, they should turn to Apple and complain to it.
