Fortnite recently returned to the U.S. App Store and quickly claimed the top spot on the App Store charts as the number one free game.
Apple allowed Fortnite back but through Epic Games Sweden subsidiary due to the ban on Epic Games' original developer account.
Apple had to adjust its App Store rules to permit developers to link to external purchase options for Fortnite, which offers in-game purchases without giving a cut to Apple.
Apple is still appealing the court's ruling on changing App Store rules, and several companies have supported Epic Games in this legal battle.
