Apple posted a couple of reminders this week about the upcoming deadlines for complying with the App Store review guideline changes announced at WWDC.

Apps in the Kids category and apps built with web technologies both have guideline changes that come into effect on March 3rd. You’ll want to read both of those to check whether you’re affected, but the main reason I mention them here is that I laughed out loud when reading that second one:

Apps that dynamically provide core features and functionality with web technology like HTML5 are best delivered through Safari, rather than through the curated App Store.

We sure have come a long way from the “sweet solution” that Steve announced on stage back in 2007. I know I’m happy that wasn’t the actual plan!

Where does the Swift project go next? Here’s Ted Kremenek with a recap of the goals of the project in general, as well as some food for thought as we move towards whatever becomes Swift 6. It also contains some important clarification that Swift 6 isn’t going to be the next release after 5.2. We’ve got several more 5.x releases to come first. 👍

Dedicated to the unsung studio designers, copywriters, producers, ADs, CDs, and everyone else who creates wonderful things.

Dedicated to those who stayed up late and got up early to get on the family iMac to recreate event slides in Keynote.

This is a remarkable resource from Sam Henri Gold… 👏

Tools

There are two interesting things about this project from Michael Eisel. First, I really like the idea of using multiple, temporary AppDelegates to increase your productivity when working with a specific view controller, or section of your app. Then, once that’s done why not speed up your build times by only compiling what’s necessary for what you’re working on.

This dedicated Core Data SQLite client looks very promising. Not only does it give you a clean, sanitised view of your database with all of the Core Data artefacts abstracted away, but features like live change tracking look very interesting. I haven’t had a chance to check it out properly myself yet but there’s a free trial available, so there’s nothing to lose if you’re working on a project that uses Core Data.

Jesse Squires with a great tip that’ll have you skipping around your Xcode projects like a pro. I’m going to show my age here, but I fondly remember the Borland Turbo-C editor’s dedicated keyboard shortcuts for setting and moving to bookmarks across source files. I missed that feature for years when I moved to more modern IDEs. Maybe this is how I get them back?

Dominik Hauser with another tip that means you’ll never have to write print("Entering MyAwesomeViewController") again. I really like this.

Code

Sarun Wongpatcharapakorn with a comprehensive look at a whole load of different aspects of using Sign in with Apple. He covers apps, the private email relay service, token verification, and the web.

It’s often the way with brand new technologies that everything goes swimmingly, right up until the point that it doesn’t. 😬

I love SwiftUI. It’s such a great technology and so much fun to use. And it recently sent me on a days long tangent to figure out a problem that used to be quite simple.

I really enjoyed this puzzler from Sven A. Schmidt.

I’ve always preferred preconditionFailure over fatalError but now Jeff Johnson has given me a concrete reason why I was right to prefer it. Thanks Jeff! 👍
