WWDC 2019 :: what to see

At WWDC 2019, Apple showed one of the best Keynote presentations over the past few years. But this is only the beginning. We are waiting for more than 100 sessions from Apple engineers. I gathered in the list of reports that, I think, will be useful to most iOS developers. If you do not know what to undertake, then try to start with them.

Please note that not all reports are available yet. You can watch them either live (Moscow time), or a couple of days after the broadcast. Check the time with the official schedule , as it may change.
