Actually, no, they did not. On the Ipad page on their site: https://affinity.serif.com/photo/ipad/ "The iPad version will have nearly all the tools and features of the desktop version, and of course have full file compatibility. We do still have a little way to go before it’s ready, but to make sure you stay up to date with progress, are informed about possible inclusion in a future test flight, as well as being told as soon as we launch please sign up below."
I would prefer to have this question answered by one of their staff. Thanks. :)
