Apple has not yet officially announced the date of the conference for developers. But, according to an anonymous source, who knows the plans of the manufacturer, WWDC 2018 will be held in the same place as last year - in the McAnery conference center in San Jose.
Last years, Apple held a conference in June. According to the schedule of the McAnery Center, all dates are already booked this month, except for one working week: from June 4 to June 8. It is not difficult to guess that the event will be held, most likely, these days.
What to expect
The conference should show iOS 12, as well as new versions of macOS, watchOS and tvOS. According to rumors, in addition to "software", Apple is announcing the updated iPad Pro. The tablet can get TrueDepth, FaceID and a cutout for the camera, like the iPhone X.
