SWIFT EVOLUTION

An overview of last week's Swift Proposal state changes. Check them out when they're in review, as it's your opportunity to influence the direction of Swift's future.

No changes, but hey, we got WWDC!

QUESTION OF THE WEEK

What is it like to visit WWDC?

You might notice that this is a bit of an odd newsletter edition. I'm writing this issue on a Thursday after a whole week of WWDC events. It's a fantastic event, full of meetings, events, and announcements.

My first WWDC was in 2013, and I recall watching at least 15 sessions by Thursday. Now, I barely find the time to write this newsletter since there are so many events to attend!

Many companies organize parties, and there are community-driven events like CommunityKit where I even got to host a RocketSim meetup (with a fun paperplane challenge). But aside from that, it's been an opportunity to meet with many Apple engineers and relationships.

Getting to WWDC in person, even without a ticket, can make a huge impact on your inspiration and motivation. You'll be able to create new relationships, contacts that might turn into opportunities years later.

I attended WWDC in 2023 as well and met an engineer who worked at Meta. Now, two years later, I got invited to present my developer tool RocketSim in front of the app developers of Meta, since it's their go-to developer tool for recordings & design comparisons.

Now, it's time to rewind and get back home. I'll be going through all the changes in the upcoming week, writing new articles, and updating my Swift Concurrency Course. I hope you've had a fantastic WWDC week, whether you were here or in person watching many of the sessions. Stay tuned for new SwiftLee articles soon!
