We have no indication of the many, many other copycat apps that were let through may also already support Swedish. So if that low hanging fruit is covered, scratch that as a distinct feature...
I don't care what Apple or you think. I’m calling both you out for being insensitive or at best oblivious douchbags and telling you you’re wrong. You are free to disagree but your comment is going dangerously grey so citation needed on your assumption about how many others agree with you.
1. Apple doesn't actually have a "no copycat apps" policy, instead its an unwritten and inconsistently enforced rule
2. In this case, providing a Swedish version of the game is actually good for users and arguably should be encouraged

4.1 Copycats
Come up with your own ideas. We know you have them, so make yours come to life. Don’t simply copy the latest popular app on the App Store, or make some minor changes to another app’s name or UI and pass it off as your own. In addition to risking an intellectual property infringement claim, it makes the App Store harder to navigate and just isn’t fair to your fellow developers.
