Happy Thursday! We’ve now had around a week to look more into Xcode 11.4 and it is an amazing dot release. The community was very quick to jump on it too, and I’m very happy about that. The feature that seemed to have excited people the most was push notifications in the simulator, and there are an article and a tool in today’s edition that help you with that. Let’s go to this week’s links!

Happy Thursday! The first beta of Xcode 11.4 is out, and it’s a big one 😁. Go read the release notes and I’m sure you’ll find at least a few things that will make you happy. Swift 5.2? Support for push notifications in the simulator? iOS/macOS bundles and universal purchases? A fix for that annoying bug that doesn’t let you add a 0 constant constraint in Interface Builder? Huge improvements for XCTest? I’ve been having fun watching the reactions on Twitter, and there really is something for everyone. A lot of people were excited for different things. Great job by the people working on dev tools at Apple! 👏

Happy Thursday! I’ve featured Dave Verwer’s iOS Dev directory last year. Now, there’s a very nice project built on top of it. Andrew Yates built iOS Dev Blogs, a feed that aggregates content from the iOS Dev Directory. It’s a really good resource if you want to stay up to date with what’s being published in the iOS dev community. Beware, though, there’s a lot of content 😁.

Happy Thursday! It’s (still) the beginning of a new year, so it’s time to think if you want to attend a conference this year. Or maybe even speak at one? Conferences are great places to meet like-minded people, and if you can attend one, or speak at one, I would totally encourage you to do it. But which conference to choose? There’s this already classic link where you can see all the announced upcoming conferences, which has a new awesome feature: get an
.ics file with the conferences and import it in your calendar, or subscribe to it Google Calendar.
In other news, Ted Kremenek posted about the road to Swift 6 and I must say, it sounds very good. They had me at “Faster builds” 😁.

Happy Thursday! I need to start this edition of our newsletter talking about a new book: Swift for Good. Swift for Good is a book with 20 chapters, each written by a different author, on a different Swift or iOS related topic. It’s an amazing effort, and besides it being an awesome book, all the revenue will go to Black Girls Code. And yes, that’s all revenue, not all profit. The authors donated their time and knowledge and worked for free. Please help spread the word or consider buying this book to learn something new and to help a great cause!
