I made a video where I explore fundamental concepts for swift concurrency, like isolation domains, Sendable, etc.
Understanding these concepts helps a lot when it comes to migrating to swift 6.2 and to choose the right tool for the job when solving compiler errors

Yesterday I encountered a small unexpected behavior when doing `self.count = count` where count is an optional state property.
I would have expected to be a compiler error, but instead it was a weird behavior.
Luckily Sarunw had a great post about it sarunw.com/posts/state-...

TIL: closures are reference types in Swift, then they don't behave well with `@Entry` and `EnvironmentValues`.
The way then is to wrap them in structs, like how SwiftUI's `DismissAction` works.

A coworker recommended me to turn on spelling on Xcode. OMG, the code is so much nicer without typos, and is way easier to spot them :D

I am a fan of Ali Abdaal's work in general. I particularly liked this video about audio books.
Paraphrasing
"A blog post or a YouTube takes a week to make... a book can take years". So you get way more valuable content of all the effort that took to write the book

.@dimillian.app I was struggling with `Text` and `AttributedString` with paragraph styles, your post helped! and sadly is till valid now dimillian.medium.com/swiftui-attr...
SwiftUI AttributedString is not there yet
You should use it, but also be aware of some of its limitations

it's surprising how annoying can be to deal with live activities via push notifications.
APNS request are accepted, 200 ok, but nothing happens on device and the attached log calls don't show anything

I made a whole video about live activities.
Still, making a live activity for the SATS app has been challenging.
Remember: you need to send dates as timestamps since 1970!
