It is expected that during the keynote event, Apple CEO Tim Cook will show off the latest versions of its iOS, OS X, tvOS, and watchOS operating systems and he may also launch new features for services like Apple Pay and iCloud.
Days before the conference, we've compiled all of the rumors that we've heard about features that could potentially debut at the event.
Apple's operating system for iPhones and iPads has not seen design changes since iOS 7, which means that iOS 10 could feature some design tweaks to update the look of the OS. A dark mode is likely to become a possibility which has been circulating based on the look of Apple's WWDC app and site. Apple has not released much information on iOS 10. Apple may also introduce a Siri SDK, allowing Siri to interact with third-party apps in new ways. It is learned that iOS 10 will have a redesigned Music app featuring a more intuitive user interface for Apple Music.
OS X 10.12
Apple did not bring any major update in the OS X last year, but it is expected that 2016 will bring lots of updates to it. OS X 10.12 is expected to bring Siri to the Mac for the first time, allowing the personal assistant to be used on Mac devices like it is used on iOS devices. Siri will be enabled through an icon in the OS X menu bar, the dock, a user-specified keyboard shortcut, or through a hands-free "Hey Siri" command.
tvOS 2 and watchOS 3
Apple is going to launch new versions of tvOS and watchOS 3 at WWDC. As of June 1, Apple is requiring new Apple Watch apps submitted to the App Store to be native apps, suggesting Apple has plans for deeper native app capabilities. A push towards native apps will help in the production of a Apple Watch apps that are able to open more quickly and work more smoothly in watchOS 3.
Apple is working on several new features for Apple Pay and it is expected that all these features will debut at the event. Apple is planning to bring Apple Pay to web browsers, allowing Apple Pay users to make Apple Pay purchases in online stores directly through Safari, and rumors suggest the feature will debut at WWDC.
Following its recent conflict with the FBI, Apple may plan to introduce new security features in iOS 10 and OS X 10.12. Encrypted iCloud backups is a good possibility. Apple has not implemented this in the past because it makes the restoring process more difficult.
Weeks before the WWDC, some major changes were announced by Apple to the App Store and it is expected that the company will reveal some more at the event. Apple opened up app subscriptions to encompass all product categories and introduced a new subscription revenue split.
