I did some electrical works at home today with ChatGPT 🙈

I needed to connect some Soviet era wiring to modern wiring. And the Soviet wires were fine but the color coding was weird and didn’t match anything modern

So ChatGPT taught me how to measure the voltages with multimeter correctly and figure out what is what (and it had of course plenty of safety warnings for working with live wires)

In the end, I figured it all out and got it to work, thanks to ChatGPT

#Swift #Testing

TIL about Swift Testing:

The fancy new test parameters should only be simple value types. If you have the parameter as struct/class, you can’t have any code there which wants to run on a particular thread/actor

For any threaded stuff, grab the parameter value, and do the work in the test function which CAN be MainActor

Even if you have the entire test suite as MainActor, the parameter value is not constructed on main actor (this part was counterintuitive/unexpected for me)

#wwdc25 #macOS

This is one visible change in macOS Ui

Menu items can now have icons, exactly as in iOS context menus

This applies to both context menus and menu bar menus

If you have a menu item with a label that has an icon, and it was showing up on iOS already, it will now also just show up in macOS

#wwdc25 #Xcode #AI #LLM #FoundationModels

If you want to use Xcode AI features, OR if you want to use Foundation Models AI API on iOS Simulator or macOS, looks like the only supported configuration is having Tahoe beta on the internal SSD of your Apple Silicon Mac

I sort of get why, see the thread (tl;dr: probably performance), but is there any official info from Apple about this requirement? Nothing in the few WWDC videos I saw so far

Okay so how ARE we supposed to run the new macOS betas?

- From an external bootable SSD - turns out Apple Intelligence and a lot of AI (incl new Foundation Models) aren’t allowed

- VM - looks like this method is broken too

- The only third option that I can think of, is to dedicate an entire separate real Mac just for the beta. I’m not that rich

Has anyone seen the Foundation Models actually working? Am I holding it wrong? I am not getting any responses either in the playground or app, and there is a bunch of this crap in the console when running the app.

Running Xcode 26 beta on macOS 26 beta.

Are there regional restrictions? Xcode AI chat also is “unavailable in my region”.

#wwdc25

Is there no “What’s new in AppKit” video this year?

There is one specifically about new design, but no general AppKit video?

#wwdc25 #Xcode #Feedback

When you have multiple SPM targets and run tests in Xcode, the result indicator is missing for the target

When you expand, you see individual test results, but no result indicator in collapsed view (which was really useful to see results for lots of targets when they are collapsed)

#wwdc25 #Xcode

This is unfortunate

AI chat in Xcode seems to be gated by region

Is there a list of regions somewhere?
