YouTube video by Crafting Swift Mastering the concurrency concepts for Swift 6.2

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

YouTube video by Ali Abdaal My ONE Piece of Advice for Someone in Their 20s

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

SwiftUI AttributedString is not there yet You should use it, but also be aware of some of its limitations

.@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...

@charliemchapman.com I think in Framous, the restore purchase button is not working (at least for me), FYI

Hey Natalia, do you know how to do the navigation bar effect in UIKit or SwiftUI?

I can manually make it in UIKit, but such a "common" pattern specially in screens with stretchy headers doesn't seem to have a good public API, that I know of.

YouTube video by Crafting Swift Why you should be doing hackathons at work

New video! I discuss how we run hackathons at my day job and share tips for organizing one at your company

This is quite relevant with WWDC 2025, as Hackathons are a great arena to try out new Apple APIs

YouTube video by Crafting Swift Keeping track of WWDC Sessions with Notion

I re-share my video on how I watch WWDC sessions.

Notion is great to keep things organized #wwdc #appledev #swift youtu.be/tEAS5rUfMLE

Also my channel is growing :D

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

also my sample project helped me a lot 🤣

YouTube video by Crafting Swift Design and develop Live Activities with ActivityKit for iOS 18

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!

What do you use for these graphics? Sketch, figma? Something else?

I think you have tons of graphic design knowledge you can share. Maybe as a course?

YouTube video by Crafting Swift How to animate views as you scroll in SwiftUI

New video out! This time I share a quick tip on how to animate views driven by scroll on SwiftUI! I focus particularly in the position of a view inside a scroll view to drive animations.

A quick and handy technique to drive animations like the App Store app does

YouTube video by Crafting Swift How to modularize an iOS app with SPM packages

New video alert! In this one I share how we split our code at my day job using local SPM packages!
I go through my sample app from the latest videos and divide it into packages to be able to resuse code and work on isolated modules of my app

www.youtube.com/watch?v=IjoX...

in general, I think developers and designers don't put enough attention to the navigation bar and the loading/error states as they should

I've been working on iOS for 7 years now. I love to learn each day more about this platform and try to make the best apps possible.

@jordanmorgan10.bsky.social now I'm reading the design book in your collection. I really appreciate your insights and your goal of "best in class" apps.

@seanallen.bsky.social you can check my video Design and develop Live Activities with ActivityKit for iOS 18
youtu.be/mu9LlmUYC9E and promote it on swift news if you think it’s worth sharing :D

My new video is up! This time I go how I would implement navigation on a medium to large iOS application with a pattern extracted from the app from my day job, so it's based on real world aplication.

YouTube video by Crafting Swift A year of reading for an iOS developer

I made some recommendations from the books I read last year youtu.be/IBh2y0O6-io?...

One my daily routines, before starting my work day, is that I spend 10 min reading a book, also on weekends.

I like start my day by learning something and so far these are the books that I have read this year

I just finished your book @natpanferova.bsky.social

A lot of good advice. I have a bunch of highlights in the book. Certain parts, like the Text chapter was awesome and also your explanation about preferences, finally helped me make sense of this feature.

Recommended read!

YouTube video by Crafting Swift Building UI that is easy to Preview and Test with SwiftUI

In my new video, I share how we architect my day job app to make the view code that we write easier to preview and test.

It includes a full sample project that is a clone of the Apple TV app, but focused in movies youtu.be/KZBr0wlS3K0

I finished the first book now. It was great, there was tons of things I didn’t know, like the borders for clickable elements, the use of color for meaning, etc. great book! Now I need to practice
