Apple Newsroom:

WWDC kicks off with the Keynote and Platforms State of the Union on Monday, June 8. The conference continues online all week with over 100 video sessions and interactive group labs and appointments, where developers can connect directly with Apple engineers and designers to explore the latest announcements. The conference will take place on the Apple Developer app, website, and YouTube channel; and on the Apple Developer bilibili channel in China.

I’ve never before heard of Bilibili, which seems to be a Chinese equivalent to YouTube.
