Wrote this one a while ago but it still seems to be helpful for people.

Swift concurrency through a step by step examination of a network request. #SwiftLang

Concurrency Step-by-Step: A Network Request

When I was first learning to program I had absolutely no idea what I was doing. I was using C, and I remember desperately putting in * and & characters until things compiled. But, this was pre-Mac OS ...

This is good!

One part gave me pause. “on a different thread or executor”. Different thread yes. But I don’t *think* a different executor is actually possible. It might be, but I don’t immediately see how. Is it?

Ohh huh! How does this work? It is aggregated? Are these reports tied to the user that submits them?

Thanks to a single comment in a talk on Xogot by @migueldeicaza.bsky.social, I have now learned about the “Pit of Success”. I think it is *possible* I will be thinking about this concept for the rest of my life.

Racism is rampant and I would expect no less, so while unsurprising it is still disappointing

I've been inspired to update my "Concurrency Step-by-Step: A Network Request" post for Xcode 26/Swift 6.2.

Quite pleased that I was able keep it settings-independent. That will not always be the case.

I hope it is useful!

I wrote a little blog post about one of my favourite topics: UI jank

Been thinking about writing more of these shorter posts, lemme know what you think about it! harshil.net/blog/swiftui...

The attendant on the Eurostar speaks, at a minimum, English, French, and Japanese.

Je lui ai parlé en français, et il n’était pas horrifié (visiblement).

Very high level take away from @serversideswift.info (which was fantastic for many reasons): these people know *a lot* about performance. Kind of a wake up call for me.

Do what you can. Boycott, sure. Quit, if you cannot continue/have the privilege. Withhold feedback, especially if you are an employee. Your work is being disgraced and you have coworkers they are coming for.

I don’t 100% understand this, but seems like a bad move

Matt Massicotte @massicotte.org · 7d

I have been rehearsing and I just cannot remember to say this. So here’s a spoiler from my talk in case I forget again:

“Approachable Concurrency” is just a big group of settings. It is completely independent of making the default isolation MainActor.

Super pumped for Bridges 2.0 🥳. I have been working hard over the summer to update my link saving app for liquid glass and shortcuts. The app is a must have if you are working with lots of links for projects and need them in different formats.

Check it out 🙂

A promo image for my link saving app Bridges. It shows how the app now looks using iOS 26 and Liquid Glass. It has three iPhones one with a home view of the app. One with a detail viewer for a link that was saved. And one showing the share sheet where you can save a link to the app.

A promo image for Bridges 2.0 my link saving app. It shows two iPads one with the shortcuts app showing some of the shortcuts you have with it. And the other an iPad showing the app running on iPadOS 26.

There were many! Core Data just has a bunch of APIs to do this. Here’s one example: github.com/davedelong/e...

I have learned two things. First, setting up a Core Data system programmatically is pretty easy. Second, you all know a lot about Core Data.

Does anyone have an resources handy for a way to set up a Core Data system programmatically, including the model definitions?

(I am trying to set up a test suite and I think having to dig into an Xcode-based UI every time is annoying)
