After the court ruling on May 3, 2023, Apple updated the iOS App Store review guidelines, easing restrictions for developers in the U.S. App Store. Previously, Apple lost the Epic Games antitrust case, with the court ruling that it 'intentionally' violated a 2021 injunction prohibiting Apple from charging a 27% fee on external app payments and restricting redirect behaviors. Against this backdrop, the new rules allow developers to provide external payment methods within apps and support users in purchasing non-fungible tokens (NFTs) through third-party marketplaces.
