Whenever I see someone ship a massively complex or cool feature / project my first thought is "Damn! How'd they know how to do that? That's so smart!".

And then I remember that the road to get there was most likely messier and harder than it looks.

Don't compare yourself to other's outcomes; they most likely worked really hard to get where they are.

[Donny Wals 👾 @DonnyWals]

Honestly, the biggest Swift Concurrency trap you can set for yourself is thinking that you need to know _everything_.

Most apps don't need a ton of concurrency. They don't need to use the more complex and powerful features.

Most of the apps I've worked on fetch some data from the network and present that data in a list. No expensive processing, no heavy tasks that run in a background thread.

Don't overcomplicate things unless you have to. Measure performance with Instruments, don't offload to the background "just in case".

Swift 6.2's default settings reinforce this which IMO is a good thing. It helps you get started with a simple setup and allows you to make things more complex if and when needed. That's how code should be written.

If your first thought is to make everything concurrent and async for every project you work on I can promise you, you're making things harder for yourself and you really don't have to.

[Donny Wals 👾 @DonnyWals]

With Xcode 26 your projects will automatically include a setting that runs code on the main actor by default, making your decision to introduce concurrency more conscious and explicit.

To configure this setting for existing projects (or to opt out in your new projects), you can set default actor isolation in build settings:

I've been tracking pomodoros with Chrona. An app I made to log, summarize, and rate my productivity. It's been a huge boost, especially since I'm able to visualize how well I'm doing with my work. It's pretty cool 😁

Are you ever worried about overusing actors in Swift? Or are you worried about introducing more concurrency with actors?

@corneliusmark Using nested functions (1 level deep) rather than nested loops - to semantically clarify behaviour.

Swift Reduce is one of my favorite functions in Swift.

What's your favorite way of using reduce? ✨

[Donny Wals 👾 @DonnyWals]

I think it's about time I ship my first app of the year this week...

Track pomodoros, write down what you did, and review your productivity in graphs. It's a simple idea, but it's been working _really_ well for me these past few weeks. 😁

Just a few more small things to fix before I'm ready

How much time could you save with timezone and locale testing?

I’ve released an update for Discretion today. It now enables you to create Genmoji face masks on iOS devices with Apple Intelligence support. There’s also a Feature Roadmap which allows you to vote for your favorite proposed features.
