Epic Games, the maker of Fortnite, said on Friday that it would launch an alternative app store for iPhone users in Europe. Spotify this week began directing European users on its iOS music streaming app to the company's website to sign up for a subscription, which was previously not allowed. In addition, Apple said Wednesday that it plans to allow developers in the United States and several other countries to offer secure contactless payments through their apps on iPhone. Apple has previously pledged to open up contactless payment technology in Europe to resolve an antitrust case in the European Union.
