This error usually appears with bad dumps. Did you buy DGS from eShop or install a dump of a physical Game Card? One solution could be to dump the game again using the most recent GodMode9 or to uninstall it from your home menu and running the patcher off your Game Card. If it is an eShop copy, try deleting it and downloading it again.

There is a "proof-of-concept" version that is really just that - proof that it could be done in theory. It's not polished and doesn't have anything translated but the script. We have not researched all texture formats required for it and the binary does not have all necessary patches to get it to work. To bring it to the level of the Android version would require a lot of work.
We feel bad for iOS users and we wish it was possible to deliver a patch for it. The problem is that you are one of very few people with a jailbroken phone now. Most people are not willing to do that now according to our research. While it is possible to get self-signed apps to run on your device for 7 days using Impactor, we are unaware of a reliable method to dump the unencrypted binary for patching without a jailbreak.
Our stance is currently this: we're not ruling it out completely and we do keep an eye open for developments in the scene - but as it is now, it's not realistic.
