I didn’t think I’d ever get to see anything I had worked on in a WWDC session presentation. That’s a privilege even if you work inside Apple. It’s pretty much unheard of if you don’t.

And yet, this week, it happened. 🤯

It began when I started receiving messages and DMs from people saying, “Did you just see the mention of a package index on that slide?” during the Platforms State of the Union. I hadn’t even seen it, but a quick screenshot proved it! I did wonder for a few seconds whether we might be about to be Sherlocked, but something far more exciting was on the table.

It came in the “What’s new in Swift” session on Tuesday. 2m45s into the session, Nicole Jacque begins talking about Swift Packages, and suddenly, there’s a screenshot of the package index! Right there in a WWDC session! I couldn’t quite believe it.

I want to say a heartfelt thank you to everyone who was involved in making this happen. I have to think this decision wasn’t taken lightly, and it’s so lovely to see that people inside Apple think what we’re working on is important enough to include alongside their own work. The Swift Package Index remains the most exciting part of my work every week, and I can’t wait to see where we take it over the next year.

So, that was my highlight of this week, but that was far from the only exciting thing that happened! As usual, I’m not going to try and cover every announcement or new API today. We have several months for that!

I hope you all had a great WWDC week, and enjoy the collection of links below, as always!

New technologies from WWDC 2021

I love this! Apple has put together a page on the documentation site highlighting all the new APIs and technology that debuted this week. The page links to both specific articles/APIs like TimelineView and AsyncImage, and topic pages like this one on concurrency or this one covering the new DocC tool. I'm so happy to see an easy way to keep up with the documentation that accompanies a new release, and I hope we see more of this!

Also, there's now an official sample code index for all WWDC 2021 sample code! 😍

App Store Review Guidelines Updates for WWDC 2021

Apple also summarised of these changes, but I prefer this "diff" style version better. The most significant change by far this year is this addition to 5.1.1:

If your app supports account creation, you must also offer account deletion within the app.

I think that probably affects more than 50% of apps on the store! No one can argue it's a bad rule, though.

Package Collections on the Swift Package Index

Package collections are new in Swift 5.5 and Xcode 13, and the Swift Package Index supports them right now! We knew they were coming in Swift 5.5, so we started implementing them. What we didn't know was that Xcode 13 would also include support for them! We've updated our documentation to now include instructions for both the command-line tool and Xcode 13. 🚀

A love letter to Xcode 13 in five short video clips

Yes, Paul Hudson covered this topic in much more detail in a blog post, but I like these short videos too. My favourite features are automatic import with automatic searching of package collections and code completion of unwrapping optional values. 🚀

Vimpocalypse Now

Vim bindings in Xcode 13? You read that right! It's been a very long time since I used vim regularly. In fact, it was so long ago it was called vi! Could I re-learn it and for Xcode 13? Absolutely. Will I? Probably not. It's great news for people who still use it day-to-day, and there are many of those people still around. Here's Erica Sadun with the details.

The Future of Combine

One of the biggest topics of conversation this week has been what happens to Combine now that we have AsyncSequence and AsyncStream on the way? I liked Ben Scheirman's take on it. What I'd say is that even if Combine is deprecated next year, which is far from certain, it'll likely be a long deprecation cycle. There's no need at all to refactor any working code just yet!

Big improvements to UIButton in iOS 15

Who had "Huge changes to UIButton" on their WWDC bingo card? I know I didn't! Here's Filip Němeček with the low down on what's changed. I'll be happy to see some standardisation come back to button design with these changes.

Let's continue in UIKit land for one more article. Here's Jordan Morgan with some of the framework changes that are not related to buttons! I'm very happy to see Apple finally provide a standard way to make a "bottom sheet". 🚀

AsyncImage in SwiftUI

Since the earliest days of iOS development, we've been writing code to download and display remote images in our apps. It's probably about time there was a standard way to do it, and here it is in the form of a SwiftUI view. Here's Gabriel Theodoropoulos to tell us more. 🎉

Updated Human Interface Guidelines

It's always worth re-reading the HIG after a new release, and this year is no different. Here's Apple's guide to what sections have been added or received significant updates to help guide you through it.

Demystify SwiftUI

I'm sure I'm not alone in only getting the chance to watch a few WWDC videos this week, but one I did want to highlight was this session from Matt Ricketson, Luca Bernardi, and Raj Ramamurthy. If you've ever wondered how SwiftUI decides when to re-build or re-use views, this session does a great job of explaining it, and much more!
