In this issue: WWDC22 is announced, I’m running an all-new Advanced SwiftUI workshop in May, there's just a touch of April Fools fun, and more!

WWDC22: Call to code

Apple has just announced WWDC for this year, taking place from June 6th to the 10th and entirely online apart from an invite-only special event on Monday.

Apple’s design for this year is a huge Swift logo, and although it’s rarely possible to read much into their event graphics, it is of course fun to speculate – perhaps it’s time for Core Data to get the SwiftUI treatment?

Of course, there are lots of things we can be sure of, including new iOS, macOS, tvOS, and watchOS releases, Swift 5.7 landing with distributed actor support, and a huge collection of session videos, labs, digital lounges, and more.

Find out more about WWDC22 here: https://developer.apple.com/wwdc22/

And if you’d like to take part in this year’s student challenge, you’ll need to build a three-minute interactive scene using Swift Playgrounds. If you haven’t had chance to try out Swift Playgrounds yet, I have a tutorial that will help jump start you, available as both text and video.

Ready for Advanced SwiftUI?

I’m running a new workshop in May, teaching folks a variety of advanced SwiftUI skills they can apply to their projects immediately. It will take place entirely online, 9am to 4pm US Eastern time, and you can choose one of two days: May 4th and May 8th. Everyone who signs up gets a free book of their choosing from my collection, plus access to the whole workshop as a video to watch later.

While taking the time to hone your skills is always a good idea, these two workshops both have a second major benefit: all income from ticket sales goes to charity! I am raising money to help two Afghan girls come to the UK to study, because they have been denied access to education since the Taliban took over.

So, by coming to the event you’ll get a whole day of SwiftUI education, plus a free book of your choosing and access to the recordings, but you’ll also be helping make a difference in the lives of two refugees. I love learning and teaching, but nothing ever beats helping other people!

If you’d like to attend the event, you just need to donate at least $100 / £75 / €90 to the fundraiser here: https://www.justgiving.com/fundraising/advanced-swiftui

You're welcome to buy tickets for yourself, but if you buy extra I’m happy to give them away to folks from underrepresented groups in our community!

Thanks to sponsors!

I’m really grateful to Emerge, RevenueCat, and Fernando Olivares for sponsoring the site last month!

Emerge has a fantastic blog teaching advanced performance tips and more, such as why Swift reference types can be bad for app startup time. Find out more here.
RevenueCat lets you make more money on the App Store and spend less time managing in-app purchase infrastructure, all with their powerful SDK. Find out more here.
Fernando Olivares has a free weekly newsletter covering all phases of learning. Starting out? Learn to stay positive! Already looking for a job? Learn interviewing skills. Find out more here.

Hacking with macOS: Now updated for SwiftUI!

It took a lot longer than hoped, but I've finally released a major rewrite of my book Hacking with macOS, with all the AppKit projects now rewritten using SwiftUI. This was a huge chunk of work, but it shows how to create apps that take full advantage of the extra screen space and power that comes with macOS.

Even better, the book is a free update to everyone who bought Hacking with macOS previously, or bought it through the Swift Platform Pack bundle – just go to your Gumroad library and the update will be there waiting for you!

News from friends

Conferences are really swinging back into action, some online, some in person, and some offering both, so hopefully you can find something that suits you:

App Builders takes place May 16th and 17th in Locarno, Switzerland
Appdevcon takes place June 20th through 24th in Amsterdam
SwiftConf takes place August 17th and 18th in Cologne, Germany
360|iDev takes place August 28th through 31st in Denver
iOS Dev UK takes place September 5th through 8th in Aberystwyth, Wales

Even if you’re attending events like these online, they are a great place to learn something new, meet others, and hopefully enjoy yourself too!

Some April fun

Normally I aim to send out my newsletter on the 1st of each month, but I wanted to avoid it this month because it was of course April 1st – April Fool’s day, also known as “stay off the internet day.”

Anyway, I enjoy a bit of fun, so I put out a couple of things you might enjoy:

Swift Core Team to Swift bloggers: “Please, for the love of all things holy, find a different color than orange” – read the article here.
Barking with Swift: Swift tutorials by dogs, for dogs – watch the video here.

I also enjoyed this announcement from Antoine van der Lee: a tool that lets you inspect the SwiftUI code behind any app in the simulator!

Swift jobs

I have a dedicated forum where folks can post job adverts, and I want to pick out a handful here:

One more thing…

March was a difficult month for my family for a range of reasons, and April is somehow going worse. I’m rarely good at replying to emails quickly, but please be extra patient right now.

If you’re also facing a hard time right now, keep going – we’re going to get through it! 🙌
