This year's Apple Worldwide Developers Conference will be another all-online event. It will take place from June 6 to 10 and will be free for all developers to attend. As with past WWDC events, you can expect to hear about the latest developments in iOS, iPadOS, macOS, watchOS, and tvOS.
On June 6, Apple will host a special day for developers and students at Apple Park so they can watch the keynote and State of the Union videos together alongside the online community. Space will be limited, so Apple will release details on how to apply to attend over at its Developer site and app soon.
The company will also be holding its Swift Student Challenge for the third year. Apple invites students worldwide to create a Swift Playgrounds app project on the topic they want. They can submit their work through April 25. You can get more details here.
