That’s it, Xcode 15 Release Candidate has been available since the middle of last week!

This means that we can now start using the new features of Swift 5.9 in production, including Swift Macros 🥳

So here’s a list of 3 Macros from the community that you can start using today!

If you’re like me, you might have been a bit disappointed by the lack of any new AI-based feature that helps developers write code in Xcode 15.

That lack of an AI feature is even more frustrating when you know that it’s been more than 2 years since Microsoft has released Copilot 🥲

But did you know that it’s actually possible to use Copilot with an Xcode project?

You’re probably aware that Apple’s September keynote will be taking place on the 12th.

This means that it is now a matter of days before the official release of Xcode 15, and along with it the release of Swift 5.9!

So how about we prepare for it by going over 3 features that this new version of Swift will add to the language?

WWDC 2023 had a lot of cool announcements, but there’s one I’m sure no one expected: the release of a new iOS framework called TipKit!

So what is TipKit all about?

The goal of TipKit is to make it as easy as possible for developers to display short contextual information that highlights or explains a feature of their app.

Since the end of 2021 I’ve been teaching private SwiftUI training sessions for a few French companies.

Their feedback was pretty positive, so last spring I decided to record this training course through a series of free livestreams on YouTube.

(and if you’re wondering about the price, it’s available entirely for free!)

I’m sure you already know about retain cycles and how they can be broken by capturing a weak reference to an instance.

You might have also heard that, instead of a weak reference, you can also capture an unowned reference.

And you might have even heard that unowned reference are a bit more optimized, but also a bit more risky.

Last June, a French company hired me for a private training session focused on SwiftUI and Combine.

This lead me to prepare some training material on Combine and I figured why not make it available to everyone?

One of the benefits of spending a lot of time on Twitter (or is it X now? 🤔) is that I see a lot of iOS folks share super useful tips!

So I went through my bookmarks and made you a list of the 5 most useful tips I’ve found 🙌

This week we’re talking about tooling 🛠️

The iOS community is known for releasing amazing content and open-source tooling make no exception to that rule!

So let me show you 5 tools that can really help improve your iOS project!

In today’s email, we’re going to talk about a tricky question that iOS developers are bound to ask themselves regularly:

“Should I use [weak self] in this closure?”

To answer this question, we’ll go over a few examples. And as you’ll see, the answer is not always as clear cut as it seems!
