In the latest development of the very public spat between Apple and Epic Games, Epic has issued a new filing in which it claims that Apple has “retaliated ferociously” to its lawsuit. While we already knew that Apple had removed Fortnite from the App Store, it’s now taken things further. According to Epic, Apple will cut off Epic’s access to development tools later this month–including those it uses to work on the Unreal Engine utilized by Epic and numerous other developers in the industry.
