The conference -- and the keynote that kicks it off -- serves as its annual reveal of each the software updates it's been working on.
As such, there will be a new iOS 15 for your iPhone, updates for the Mac, along with new features on the Watch. WWDC is unusual among Apple events in that each one of its applications platforms has an upgrade of some kind, and that they are readily available to download at no cost.
The event begins at 10am local pacific time, or 6pm in the UK. As with each Apple event throughout the last year, it is going to be held entirely virtually.
