THIS WEEK'S BLOG POST
A standard TabView in SwiftUI isn't that interesting, but have you already played around with the sidebarAdaptable style and sections? I love how easy it has become to create this kind of navigation.

CURATED FROM THE COMMUNITY
Do you recognize the scenario where you want to center content vertically in a scroll view if the size of the view is small enough to disable scrolling? The solution is shared in this article.

One wish I have for WWDC is more in-depth documentation for SwiftData. There are just too many assumptions we need to make and unexpected behavior to deal with.

Imagine detecting body poses in a live video feed 10 years ago. This is one of those articles that makes you realize how advanced today’s APIs are, including the Vision framework APIs.

I love creative solutions to navigation and I haven’t seen something like FlowNavigation before. The framework is still in beta, but the idea is promising for linear flows.

I’ve been using groups without thinking until I read this article by Chris Eidhof this week. I had no clue these differences existed!

CODE SNIPPET OF THE WEEK
Region-based isolation in Swift Concurrency
I was quite surprised when I first encountered this. I expected compiler errors about my type not being sendable, but it turns out the Swift compiler is pretty smart! Honestly, I was also surprised since my experience so far has been many compiler errors during migrations. Knowing that Swift does a lot only to send diagnostics when truly needed is super helpful!

QUESTION OF THE WEEK
“
I've encountered quite a few flaky tests when testing async/await logic. Do you know how to solve this?
Flaky tests are annoying and can easily take time to solve. A flaky test is one that sometimes succeeds and sometimes fails. For example, it could succeed when running solo but fail once executed in parallel with other tests.
The latter is an example where there's likely shared state applied: your test uses shared data modified by another test running in parallel.
If that's not your case, you might encounter a so-called race condition—depending on the order and speed of the test, your test might run into a failure or not. This won't happen easily when running tests serially, but can suddenly appear when you migrate your test suite to run in parallel.
If you've recently migrated to Swift Testing, you're now likely running tests in parallel. It might very be that you didn't before and that you're now running in unexpected test failures. Swift Testing runs tests in parallel by default, making your code more likely to be affected by race conditions.
You can resolve flaky tests by using Test Repetitions in Xcode, but that might not be enough when testing Swift Concurrency code. For this, I highly recommend using a main serial executor. Looking for more? My Swift Concurrency course will cover testing in-depth.

EARN ROCKETSIM LIFETIME
Enjoying this newsletter? Could you help me reach more Swift developers?
I'd love to grow this newsletter further, and your help could make a huge difference. I reach many developers via my socials, but word of mouth is hard to match.
You'll get several rewards along the way in return, but it's also a way for you to show your support for all the content I deliver weekly for free.
Sharing to socials can be done by clicking on any of these links: X/Twitter, LinkedIn, Bluesky. Or, probably even easier, you can share the following link in one of the Slack groups you're in:
[RH_REFLINK GOES HERE]
No worries if you don't, but if you do, I absolutely appreciate it!
Thank you so much for your support, and until next Tuesday,
Antoine
