AppCoda Weekly - Issue #220

By AppCoda Weekly • Issue #220 • View online

As expected, this year’s WWDC is still in an all-online format:

Free for all developers, WWDC21 will offer unique insight into the future of iOS, iPadOS, macOS, watchOS, and tvOS. Building on the record-breaking participation and learnings from last year’s online conference, WWDC21 is an opportunity for developers to learn about the new technologies, tools, and frameworks they rely on to build innovative and platform-differentiating apps and games. Apple also announced that this year’s Swift Student Challenge, an opportunity for young developers to demonstrate their coding skills by creating a Swift playground, is now accepting submissions.

While I enjoyed attending virtual conferences, I really hope that we can attend WWDC in person next year.

Hope you’ll have a great week ahead!

Talk soon,

Simon
