Apple revised its App Store guidelines ahead of its new  iOS 14, the latest version of the iPhone operating system coming out the end of this month.

Apple will allow streaming game companies to create catalog apps. However,  for each game in  the catalog must only  be made into its own standalone app using  Apple’s in-app payment system.

“Leading the changes is an  explicit ruling on game streaming services  like Google Stadia or Microsoft’s xCloud, which  Apple tells CNBC  are  newly allowed – but the new rules show that each and every game must also be downloadable “directly from the App Store,” and every game update must be submitted to Apple individually before a company could stream it to users. That means that Microsoft or Google can’t build a single, overarching xCloud or Stadia app that contains access to all the games. But they can offer individual games on the App Store as separate pieces of software using their streaming tech, with a “catalog”-style app that collects and links out to those individual apps.” Source The Verge
