Perhaps the most anticipated news concerns the next version of Apple's mobile operating system, likely to be called iOS 13, which powers the iPhone and iPad, and which is overdue for a major overhaul. In addition to a handful of redesigned and new features -- like a retooled home screen, system-wide dark mode and more multitasking options -- the company is also said to be cultivating greater interoperability between iOS with MacOS, the operating system used on its MacBook laptops and Mac desktop computers. This would ostensibly make it easier for developers to share code among apps written for the iPhone and iPad and Macs.

Given the precedent for hardware announcements and introductions at WWDC, there's also a chance that we could see a new MacBook Pro or iPad Pro, or some other unknown product, brought out on stage. The company could also debut the updated Mac Pro, which it has already pledged to reveal in 2019. (In 2017, the company used the event to unveil a new iPad Pro and the HomePod smart speaker.) Apple didn't respond to a request for comment.
