Just don't expect Apple to combine iOS and MacOS. Instead, "Marzipan" will rely on a software kit that lets developers build a cross-platform app just once. Whether or not it provides a much-needed boost to the Mac App Store's lacklustre offering remains to be seen. Apple is refusing to comment on the report. The app union reportedly aligns with its big bet on services: ahead of WWDC, Apple is tipped to unveil a news subscription service and a video streaming hub as soon as next month.

Apple began flirting with the idea of app ports in 2017. It previewed some of its efforts at WWDC last June, showcasing a suite of new Mac apps including News, Stocks, Home and Voice Memos that were built from their iOS counterparts using a new UIkit. Back then, Apple's Craig Federighi promised the same functionality would be handed to third-party developers this year.
