Apple's Worldwide Developers Conference kicks off on Monday, June 13 with a keynote event at 10:00 a.m. Pacific Time, where Apple is expected to show off the latest versions of its iOS, OS X, tvOS, and watchOS operating systems and perhaps debut new features for services like Apple Pay and iCloud.
Apple has said new versions of watchOS 3 will be introduced at WWDC, but we have not heard any details on what new versions of these operating systems might include. Drawing from what we expect for iOS 10 and OS X 10.12, the two operating systems could feature Siri improvements and design tweaks to match any design changes coming to iOS 10, but beyond that, we don't have any insight into what to expect. We do know that 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. At the very least, a push towards native apps is encouraging because it will result in Apple Watch apps that are able to open more quickly and work more smoothly in watchOS 3.
