WWDC23 was full of hardware announcements and even brought us a new platform: visionOS. Xcode 15 and Swift 5.9 are also in beta phase now with a great set of new features. Of course, for readers of this newsletter, there were no big surprises in the “What’s New in Swift” session (except for the large focus on C++ interoperability). But if you didn’t have the time to check out the other sessions, including those about Swift Macros which were a focus in the last 3 issues, you might want to visit the WWDC Notes project website which has a dedicated section with notes about this year’s sessions. At the time of this writing, 75 sessions from 2023 were already covered by 25+ amazing community members, and still counting. 🎉🙏

If you don’t know where to start, I’ve prepared a thread with a ~250-character-long summary twoot for each of my personal Top 25 sessions. It can both help you learn some tidbits of these sessions with minimal time & explore the ones you might want to dive into further by reading the full notes or watching the session:

Accepted Proposals

No new proposals were accepted in June. 😱 I guess that’s a consequence of 7 proposals being accepted in May to make it into the language before WWDC.

I’m also skipping the old proposal, no one seems to be using the repo anyway. 🤷‍♂️

But there are two new proposals in Review, so after the packed May issue and a light June issue this time, we might get a decent July issue next month. 🤞

Worth noting that a milestone of 400 proposals has been reached! 💯💯💯💯 🥳
