A love letter to Xcode 13, in 5 GIFs. Part one: it will automatically import frameworks as needed. #WWDC21
Part two: it spots when you're trying to unwrap an optional and completes it for you. #WWDC21
Part three: it's able to complete properties inside properties, making things like "view.corn" complete into "view.layer.cornerRadius". #WWDC21
Part four: it autocompletes all the cases for enums when you use `switch`. #WWDC21
And part five: when you loop over an array, it automatically completes using a singular version of the array name. #WWDC21
Much love to the Xcode team! 💞 If I missed something please give me a kick in a DM – Xcode 13 is already a great release and it's only beta 1 🤯

What's new in SwiftUI for iOS 15? I just spent an hour and 20 minutes answering that question with lots of live code examples – and, inevitably, my dogs 😅 Watch the replay here:
And now I’m going to make a snack, pour a glass of wine, and get busy writing – the night is still young 😎
Writing done with one minute to spare before the day ends! What’s new in SwiftUI for iOS 15, including AsyncImage, pull to refresh, swipe actions, and more, *plus* 37 all-new Xcode 13 project downloads for sample code: hackingwithswift.com/articles/235/w… #WWDC21

Lots of information about the #WWDC21 Digital Lounges:

- It's all on Slack (wwdc21.slack.com)
- Tap the lightning bolt to request help.
- Questions will be posted through a dedicated "Ask a question" form.
- Each lounge has dedicated activities throughout the week.
It's super tightly moderated, which makes sense – you can't post freely in the channels or message other attendees. An exception appears to be the study halls, where free conversation is allowed for the Developer app challenges. These challenges are sounding fun!
Over 5000 people have already joined the Slack, so I'm already feeling much love and respect for the Apple team tasked with moderating this. Please be considerate attendees, folks!

80,000 words later, I finally published Swiftly Speaking transcripts for Carola Nitz, Chris Lattner, Mayuko Inoue, Ish Shabazz, and Jordanna Kwok. Transcribing takes a ton of work, but I know it benefits folks who can't watch the videos 🙌 Find them here: hackingwithswift.com/interviews
I updated the site to include quick links to each interview, and while you're reading a section it now includes a date plus a link to the full YouTube video if you'd prefer to watch the original recording. Small things, but hopefully helpful! Let me know if you spot any typos 😅
Each speaker gave up lots of time to answer questions from the audience – here's just one from each of them:

- @_caro_n on what makes a great programming conference: hackingwithswift.com/interviews/car…

- @clattner_llvm on how Swift changed the programming landscape: hackingwithswift.com/interviews/chr…

My M1 MacBook Pro arrived today. Chances are you have various questions, but I think a whole lot is summed up in this 50-second video. (Alt text, because Twitter still doesn't make this easy: Xcode 12.3 beta unzips in 5 minutes on an M1, vs 13 minutes 22 seconds on an Intel i9)
It's clear why Apple mentioned coding in the keynote – M1 is screamingly fast for developers. I almost feel sorry for Intel!

My Unwrap project (13k lines Swift, 10k Obj-C, more) was 19.5s on Intel vs 11.7 on M1.

AudioKit (39k C, 27k Swift, 12k C++) was 73s on Intel vs 31 on M1.
Keep in mind this comparison is deeply unfair: my 16-inch MacBook Pro was literally maxed out just a year ago – 8 cores, 64GB RAM, and much more, costing $6000.

In comparison the M1 costs just $2000 and manages to hammer the Intel machine with a quarter of the RAM.

@biz84 Broadly I welcome folks trying to provide clarity when it comes to platforms. However, I don't think this was a particularly strong effort: it comes across as biased, incomplete, and a bit condescending. I don't think many iOS devs will read it and say "I should try Flutter."
@biz84 1. You don't mention at the start that you run a site specifically about Flutter, and are inherently in favor of one side.

2. You jump in immediately with "why Flutter is already a superior technology" – before you've actually shown anything.
@biz84 3. You say "Apple is a hardware company, and has no incentive in building and promoting a cross-platform framework," conveniently ignoring Apple's work in making Swift work on Linux.
