Apple has terminated Epic Games' developer account due to Fortnite's violation of App Store rules, specifically introducing a direct payment option that bypasses Apple's in-app purchase system. This move has resulted in the removal of Epic Games' titles, including Fortnite, from the App Store. Epic Games had refused to comply with Apple's guidelines, leading to a lawsuit and an escalating legal battle between the two companies. The termination of the developer account means that Epic Games can no longer submit apps or updates, and in-app purchases for Fortnite are no longer available.
