References to iOS 15 and macOS 12 have been found in the latest version of Apple’s open-source WebKit code, as noted by 9to5Mac. Apple usually does well to hide references to future software updates, however, this seems to have slipped through and has been part of the latest WebKit code since February 2021.
WebKit code commit mentions iOS 15 and macOS 12
As 9to5Mac noted, the reference was added by an Apple employee in a new commit to the open-source WebKit repository with the message “Update WKWebView getUserMedia delegate to latest proposal”. While this tells absolutely nothing about iOS 15 and macOS 12, it confirms one thing for sure that Apple will be changing the version numbers for macOS moving forward.
Instead of macOS 11.4 or something, it will have an iOS-like version number, moving from macOS 11 to macOS 12. macOS (and previously OS X) had used the number 10.x versioning for its major releases for a long time. This changes with macOS 11 Big Sur release in 2020.
Apple is still working on iOS 14 and macOS 11 at the moment, with new features being tested in the latest iOS 14.5 and macOS 11.3 betas. The current stable versions available for all users are iOS 14.4.2 and macOS 11.2.3, which released with security fixes for WebKit.
Even though not much has been rumored for the upcoming iOS 15 release yet, we have only heard from some leaks that iPhone 6s and the original iPhone SE will not be supported moving forward. iPad Air 2 and fifth-generation iPad will also be left behind with this update, making iOS 14 the last major update for these devices. iPhone 6s was released in 2016, and has received major software updates for almost 5 years now, which is a lot more than most other devices get.
Apple is expected to announce the next-generation iOS 15 and macOS 12 updates at WWDC this summer, which is expected to be held in June. Apple usually announces the event in advance in March or April, so we expect them to share the dates soon.
