I loved this tweet from Rebecca (Slatkin) Sloane this week. Yes, she wrote it to be amusing, but it’s also true.

Apple’s documentation gets a lot of criticism. Some deserved, but the “Apple’s documentation is bad” meme is harmful, especially for people starting with Swift.

Most community blog posts come from experience or experimentation. Apple documentation is from the source and verified before being published. There’s no question of what should be your primary resource! Yes, it’s not perfect or as complete as you might want/expect it to be. But, if you only gathered opinions on it from Twitter (which is a terrible idea), you could easily come away thinking it was worthless.

So, why is this newsletter filled with links to community blog posts rather than Apple documentation, then? Partly because this is a community newsletter and partly because it focuses mainly on new content. I have ways and means to keep up with what the community is publishing, but nothing like that exists for the official documentation. I wish it did!

It’s also because this newsletter isn’t about teaching anything specific. It’s just what catches my eye each week. Some of that will be educational, of course, but it mainly exists to tempt you into reading about something you might find interesting rather than solving your problems.

Also, let’s not even get started with this reply from Kathy Tafel to Rebecca’s tweet. There’s so much wisdom in these two tweets! 🚀

Xcode 12 is not compatible with Monterey

Here's one to be aware of before you upgrade to Monterey when it becomes available, presumably next month. Downgrading a macOS version or restoring from backup is not a pleasant way to spend a day if you still need Xcode 12. Thanks to Ethan Huang for the heads up.

Stack Corruption Problems in Swift 5.5

It's hard to say how widespread or severe the issues (1, 2, and 3) in this thread are, but if you're using the new concurrency features in Swift 5.5 and see stack corruption, you'll want to read this.

Vim, awk, and iOS translation files

Like Chris Wu, I remember being taught how to use sed, awk, grep, and friends back in University, and still put them to use reasonably regularly today. Unix tools excel at string processing, mainly because the output of Unix tools is all text! If you've been avoiding them because they feel old, this post might inspire you to give them a try.

How iPad Apps Adapt to the New 8.3" iPad Mini

It's been a long time since we made pixel perfect designs on iOS, but that doesn't mean we shouldn't pay attention when new screen sizes appear. But don't worry, Geoff Hackworth is here with his usual excellent summary of what's what.

SwiftUI Animation Lessons

A couple of things jumped out at me when reading this post from Adam Overholtzer on SwiftUI animations. First, don't forget to respect the user's "reduce motion" setting when throwing your views around the screen, and second, the animation performance issues he encountered on macOS 11. The whole post is worth a read, though!

Thread.sleep() and Task.sleep()

It used to be a safe bet to stick to the rule of "Never call sleep" in your code, but is that still the case with the new Swift concurrency APIs? Marin Todorov investigates.

When you first turn on an iOS device...

I love little details like this. This one from Ayden Panhuyzen reminded me of the demise of my favourite blog on this subject.

What star ratings do pre-installed Apple apps have?

How do your apps fare against Apple's pre-installed apps? Apple enabled ratings for built-in apps with iOS 15, and Ariel Michaeli checked out the results. I was shocked that some of the apps I'd consider being great, like Mail and Calendar, both rate towards the bottom of the list, while Tips is riding high with a 4.0 average! Don't read too much into this, but it entertained me for a few minutes!
