I don’t think anyone was expecting it, but this week has brought us a couple of new announcements from Apple.

First, the news that the WWDC app that we know and love has been rebranded as the Apple Developer app. Don’t get too excited though, there are only a couple of minor new features. However, I am hopeful that the app no longer being tied to the conference means we may see more content updates throughout the year. 🤞 Also, does this change of name mean the end of WWDC branding? I can see that making sense.

The second announcement is not official, but there seems to be a new event planned in just over a week’s time. Could this also mean the end of the Apple Design Awards? I guess we’ll find out soon enough.

Tools

As Keith Harrison points out, the new environmental overrides feature in Xcode 11 is so much better for quick previews than the accessibility inspector is. If you want to see it in action, you could do worse than watching Paul Hudson use it in his talk from the #Pragma conference (which is also linked in this week’s Videos section below).

Do the words “race condition” send you cold? If so, you’ll want to read what Antoine van der Lee has to say about the thread sanitizer in Xcode. Multi-threaded programming is hard. 😂

Tired of waiting for Xcode to update from the Mac App Store, or extract and verify itself from a xip, or even just move itself into place on your disk? Igor Kulman has some tips that’ll help you speed everything up.

The alternative is just to buy a new laptop, which is what I did! ⌨️

Code

You need to think about updating your UI in a different way with SwiftUI. Part of that is understanding that your UI is now based entirely on state, but what about when it gets complicated? Have you noticed your CPU spiking? Does your app crash? You might want to read this article from Javier Nigro that digs into why it might be happening.

Andy Ibanez with a great guide to this year’s improvements to UISearchController and UISearchBar. I was particularly happy to see the search token APIs finally appear publicly as we’ve needed a standard way to do this kind of UI for a long time.

Did you know that there was a full-featured command-line tool options parser hiding inside the SPM source? Derik Ramirez did! This looks like a worthy successor to ddcli which I’ve used several times over the years to make command-line tools.

Up to Speed

SwiftLint will help you write better code. It’s that simple. If you don’t currently use it, then why not let Soheil Novinfard show you how to get it up and running in your projects?

Videos

More conference videos! It feels like there’s another fantastic event every week at the moment. This week it’s the turn of the #Pragma conference from last month in Italy. 🇮🇹

I really liked this free two-part (1, 2) video from Brandon Williams and Stephen Celis where they demonstrate and explain Combine. There’s also links to their free series (1, 2, 3) of videos on SwiftUI as well! 👍
