Apple has officially announced its annual conference for developers, and that means it's time to take a closer look at what we expect the company to reveal during the main keynote.
Apple used WWDC 2015 to unveil iOS 9, OS X El Capitan, and a new version of watchOS. It also launched the music-streaming service Apple Music as well as Beats1 Radio. It's therefore safe to say we'll see iOS 10 and a new version of OS X this year. We might even see updates to watchOS and tvOS.
We've rounded-up all the rumours and speculation to paint you a better picture of what to expect, and we've added information about WWDC in general, including how you can follow the action.
WWDC 2016: What is it?
Apple holds an annual conference in California in order to showcase new software, software updates, and technologies. It calls this conference the Worldwide Developers Conference (WWDC), and it gears announcements toward developers. However, there's also a healthy dose of consumer excitement in the opening keynote.
WWDC 2016: When is it?
Apple confirmed on 19 April - following a tease through Siri - that WWDC 2016 will take place between 13 June and 17 June at the Moscone West Convention Center in San Francisco, where WWDC has been held for the last decade.
How to WWDC live-stream
Apple's main keynote will take place on 13 June in the Bill Graham Civic Auditorium at 10am PST. You can watch the entire event in real time over at Apple's WWDC 2016 live stream page.
WWDC 2016: What will Apple announce?
The next update to Apple's mobile operating system is thought to be called iOS 10. We don't know much about iOS 10 yet, but it could feature major design changes, as the look and feel of the software powering Apple's mobile devices hasn't received a significant overhaul since iOS 7 was introduced in 2013.
While iOS 7 introduced a new design, iOS 8 brought new features like Continuity and Apple Pay, and iOS 9 included more Siri capabilities, improved search, iPad split-screen multitasking, etc. We expect iOS 10 to build upon iOS 9. It might even have an improved Photos app, according to Mac Otakara.
Also, according to App Advice, which recently spotted new keys in iTunes metadata, some stock apps might be removable one day. Apple's iPhone and iPad come pre-loaded with Apple-developed apps, such as Compass and Stocks, but unfortunately, you're unable to remove these apps. Soon however Apple might allow you to remove them and therefore declutter your screen.
Other features rumoured include a HomeKit-compatible app so it's easier to set up your home and all your rooms with smart accessories that you can then control with Siri. Speaking of Siri, Business Insider claimed that Apple is internalling testing an iCloud Voicemail that allows Siri to transcribe your voicemail messages into text. The feature might launch within iOS 10.
Mark Gurman claims Apple will also roll out a new feature where all App Store apps automatically get 3D Touch home screen shortcuts that enable you to share a link to that app. This might frustrate some users, so let's hope the feature can be disabled somewhere in settings.
Apple will likely preview iOS 10 at WWDC, but it won't be publicly released until this autumn (alongside new iPhones - so long as Apple remains faithful to its past release schedule).
OS X Fuji
Although Apple only started shipping OS X 10.11 El Capitan last autumn, rumours about the next system update have been surfacing since early 2016. It'll likely be labelled OS X 10.12, for instance, but it also goes by the codename Fuji. Apple may stop referring to its Mac operating system as OS X, however.
Alongside its Earth Day 2016 announcements, Apple updated this FAQ webpage to explain to consumers how it cares about the environment and what it is doing to report carbon emissions, among other things. While that sounds boring at first blush, 9to5Mac noticed something rather interesting buried in the text: Apple used the term "MacOS". A second hint cropped up online a few weeks later, again suggesting MacOS will be the new name for OS X.
9to5Mac has also claimed that Apple's next major system update for Macs will likely arrive this autumn with an impressive expansion of Siri capabilities. Siri, which debuted on the iPhone years ago, has expanded to iPad, Apple Watch, and Apple TV, so it makes sense that Apple would bring the assistant to desktop machines.
According to Japanese site Mac Otakara, Apple is working on new versions of the Photos app for both iOS 10 and OS X 10.12. The Photos app for iOS and OS X will be updated with features to bring them up to speed with the now-discontinued iPhoto 2.0.1 for iOS and iPhoto 9.6.1 for Mac, respectively.
According to Bloomberg News, Apple wants to make its music-streaming service more "intuitive to use," so it is planning to better integrate streaming and download options as well as expand the radio service. 9to5Mac has followed up this report, agreeing that Apple Music will be totally revamped this summer with a design that's mostly black and white and a focus on cover art.
Apple Music should appear "bolder, yet simpler". The New tab, for instance, will be replaced by a more straightforward Browse tab, and song lyrics will be added so that words are synced up with tunes as they play. The For You section will even be retooled, making it better at curating and personalising content for users. Apple is expected to the new Apple Music at WWDC in June, likely alongside iOS 10.
Bloomberg News said Apple will likely push forward with a "marketing blitz" to promote the Apple Music update - and you will likely be able to test any new features straightaway thanks to Apple's public beta program.
Along with this Music revamp, Apple is rumoured to be working on a completely new version of iTunes. Mark Gurman reports on Twitter that Apple will show off a redesigned Mac iTunes app at WWDC to coincide with the new Apple Music, and launch of MacOS/OS X 10.12.
Apple Watch 2
Apple is working on the Apple Watch 2 and reportedly planning to add at least two things that'll make the new watch stand out from its predecessor.
Apple unveiled its original smartwatch, called Apple Watch, in September 2014, but it didn't begin shipping the wrist wearable until April 2015. Many people therefore didn't expect Apple to announce a second-generation version during the iPhone 6S event in September 2015 - and they were right. The new watch also didn't show up at the March 2016 event.
Instead, Apple in March cut the price for the least-expensive version of the watch (Sport Watch model) by $50 to $299. But don't think Apple has given up on updating its aging wearable. According to The Wall Street Journal, analysts estimate the Apple Watch is a $6 billion business, and so Apple is definitely working on a new version with new features.
One of those new features might be cell-network connectivity. Apple Watch 2 could also come with a faster processor. Many critics have lambasted the now year-old Apple Watch because it's not useful when away from an iPhone. You can track activity and do some things on Wi-Fi, but that's it. And its processor is sometimes throttled to extend battery life.
With cellular data on the new Apple Watch, you could presumably leave your iPhone at home, then go out and about, and still receive notifications and runnative apps. A faster processor would also make the Apple Watch 2 run smoother, quicker than Apple Watch. It's been rumoured we can expect to see this new watch at WWDC.
Unfortunately, we don't know if a cellular Apple Watch will cost more than a standard model without cellular data.

iMessage for Android
One of the last rumours to start doing the rounds claims that Apple is finally planning to bring its iMessage service to Android. As any iPhone user will tell you, it's one of the most useful features on iPhone. If true, it would mark just the third time Apple has launched an app for Android, with the first two being Apple Music and the app to help you switch from Android to iOS.
In theory this would mean anyone with an iPhone, or Apple ID, would be able to send iMessages to anyone else with the service enabled. Presumably, if Apple does launch it as a bespoke app, it would also act as an SMS app replacement. If not, that would mean yet another messaging app to be installed alongside all the other commonly used apps like WhatsApp, Facebook Messenger, Telegram, Hangouts and so forth.
WWDC 2016: Will Apple launch other hardware?
It's not very common, but Apple has used past WWDC keynotes to announce updated hardware (such as 2014's Mac Pro, AirPort Time Capsule and AirPort Extreme, and new MacBook Air). As for this year, most of Apple's Mac lineup is due for a refresh.
