THIS WEEK'S BLOG POST ​Testing push notifications on the iOS simulator​ Many apps support push notifications, but Xcode doesn't provide an easy way to test them in the Simulator. Your options are limited, and many developers reach out to their physical device combined with some kind of testing server. Luckily, there's a native Mac app that allows you to test right in the Simulator. A productivity boost awaits!

I've had a short discussion on X about this: will WWDC have a positive impact on Swift Concurrency? While most changes are unpredictable, we can assume many positive changes are coming to Swift. I would be surprised if we did not get a Swift 6.2 release with Xcode 17. Historically, there have always been changes to Swift that didn't go through Swift Evolution Proposals. Let me be clear: most changes do happen through SE proposals! Yet, it makes me highly positive about what's coming next. I've seen the accepted proposals—(you did too, if you carefully watched the above section in this newsletter)—and they're promising. Last week, I gave a talk at Deep Dish Swift about Swift Concurrency and had the chance to discuss this topic with several other developers. In my talk, I said that Swift Concurrency will become less daunting. Let's say I've had a so-called birdie moment to confirm my statement. Stay tuned! Want to have your question answered next week?
