On May 3, 2023, Apple updated the iOS App Store Review Guidelines, relaxing restrictions for developers in the U.S. App Store. Previously, Apple lost the Epic Games antitrust case, with the court ruling that it had "deliberately" violated a 2021 injunction that prohibited Apple from charging a 27% fee on external payments and restricted certain behaviors. Against this backdrop, the new rules allow developers to offer external payment methods in their apps and support users in purchasing non-fungible tokens (NFTs) through third-party markets.
