I haven't seen anything about this yet but is supercell aware of the replaykit framework that apple introduced in iOS 9? I've been trying to figure out how to record gameplay but have been unsuccessful. Maybe supercell can look into integrating this feature for iOS users. That way we can us the existing framework to record attacks in clan war and loot raids.
That's a fantastic idea, I didn't even know about the replaykit until now.
It's been a long time now, but I remember it was quite the process to mirror and record and extract and whatnot to make a video from Clash of Clans on my iPad into my computer.
