Apple’s Worldwide Developers Conference (WWDC ) traditionally unveils its latest software updates for iPhone, iPad, Mac, Apple Watch and Apple TV.
It gives developers the chance to meet Apple engineers, sit in on workshops and software sessions, and discuss the technology giant’s upcoming releases.
This year’s conference is being held at the Bill Graham Civic Auditorium, San Francisco, with tickets costing $1,599 (£1,119).
When does it start and how long does it last?
This year's conference is taking place between 13 and 17 June – the conference begins at 10am in San Francisco and 6pm in the UK.

What is expected to be announced?
WWDC 2016 will focus on updates to the software for iPhones, iPads, Macs and Apple TV, with Siri set to be given major updates across all platforms.
Most excitingly for iPhone enthusiasts, the conference will reveal details of iOS10, Apple's latest mobile operating system. The next iPhone is due to be released in September, with iOS10 expected to run alongside that release.
It is rumoured the operating system will feature a new design and the ability to delete Apple’s Stocks app. On top of this, Apple CEO Tim Cook has said he wanted users to be happy, and be able to hide apps such as Games Centre and Reminders for good.
For macOS, the Mac operating system, this year could see the introduction of Siri, following its integration with iOS, watchOS and tvOS. The Mac integration would see a Siri microphone on the Menu Bar, which will launch a voice assisted programme.
The conference is also expected to unveil a third version of the Apple Watch, along with new features, which could result in the release of an Apple Watch 2 later this year.
It has been rumoured Apple will release its own streaming service to rival Netflix and Amazon Prime TV. However, following reports that Apple has not yet settled on programme costing, it is unlikely it will be unveiled at WWDC.
Other Apple products expected to feature at this year's conference are Apple Music, with the Spotify competitor set to be given a complete re-design, and Siri which could allow users to use it to work other apps such as Uber and possibly Apple Play.
