Just noticed that my talk from try! Swift Tokyo got featured in Tech Talks Weekly 🙌 www.techtalksweekly.io/p/issue-101-...

The onChange() modifier in SwiftUI has gone through some API changes since it was introduced. I wrote an overview of the modern variants, including how to access old and new values, and trigger the action on initial appearance: nilcoalescing.com/blog/Overvie... #iOSDev #SwiftUI

Starting with Swift 6.2 and iOS 26, EnumeratedSequence conforms to RandomAccessCollection, allowing enumerated() to be used directly in ForEach and List views in SwiftUI: nilcoalescing.com/blog/UsingEn... #iOSDev #SwiftUI

List in #SwiftUI is only lazy when it can determine how many views a ForEach element resolves to without evaluating the closure. Using an `if` statement inside ForEach, or wrapping rows in AnyView makes SwiftUI evaluate the ForEach closure for every element before any rows are displayed.

Got home from Japan and try! Swift Tokyo, the trip was amazing! It was so good to meet the local iOS community and explore Tokyo a bit. Thank you so much for having me @tryswift.jp ☺️ #tryswift

Register your macOS app as a login item using SMAppService: nilcoalescing.com/blog/LaunchA... #macOSDev

Got the nicest feedback about my SwiftUI books, it made me really happy 🥰 "... the explanations of view identity and data flow made sense in a way that just hadn’t gotten through to me no matter how many other tutorials or bits of Apple documentation I read."

The new backgroundExtensionEffect() SwiftUI modifier in iOS 26 lets us extend and blur visual content beyond a view’s bounds, creating continuous backgrounds behind elements like sidebars, inspectors, and overlay controls: nilcoalescing.com/blog/Backgro... #SwiftUI #iOSDev

Today was the last day of the try! Swift Tokyo conference and also the day of my talk. I think it went well 😌 Thank you so much to everyone involved @tryswift.jp for such an amazing experience! #tryswift

Heading to Japan tomorrow for @tryswift.jp ✈️ I've never been to Tokyo or the try! Swift conference before, so getting to attend and speak is a dream! Can't wait to meet everyone! tryswift.jp/en/

SwiftUI offers several methods to change the color of text, including foregroundStyle() and tint() modifiers, AttributedString attributes, and the textRenderer() API for advanced styling: nilcoalescing.com/blog/Foregro... #SwiftUI #iOSDev

Published a new YouTube video covering some advanced techniques for working with Optionals in Swift. I shared these as part of my presentation "Swift's Hidden Gems" at the ARCtic Conference and many developers were surprised youtu.be/qgDIOrKnmuw #SwiftLang

I wrote a post on how we can embed SF Symbols in Text and style them with modifiers in SwiftUI by leveraging LocalizedStringKey interpolation: nilcoalescing.com/blog/Embeddi... #iOSDev #SwiftUI

SwiftUI is approachable at first, but in real-life projects it's easy to make mistakes that can compromise app stability and performance. My new book "The SwiftUI Way" will help you recognize the most common anti-patterns and choose better alternatives: books.nilcoalescing.com/the-swiftui-...

The March issue of the Nil Coalescing newsletter has been sent out and is now available online. I shared details on my new book "The SwiftUI Way", talk recordings from the iOS conference in Singapore and plans for April: nilcoalescing.com/newsletter/2... #iOSDev #SwiftUI

“The SwiftUI Way” is a new book by @natpanferova.bsky.social written for SwiftUI developers who want to develop a deeper intuition for working with the framework, recognize potentially harmful anti-patterns, and build more maintainable and performant SwiftUI apps: nilcoalescing.com/blog/TheSwif...

My new #SwiftUI book is finally out 🎉 I wrote "The SwiftUI Way" for developers who feel like they are fighting the framework as projects grow in complexity. The book will help you align your code with SwiftUI's internal expectations to avoid common pitfalls: books.nilcoalescing.com/the-swiftui-...

The recording of my talk from iOS Conf SG is now available on YouTube! In this talk I share 5 key ideas for building a SwiftUI mindset and show a few examples of what can go wrong in practice when SwiftUI principles are misunderstood: www.youtube.com/watch?v=Y_Ov... #SwiftUI #iOSDev

On iOS 26, we have a new #SwiftUI modifier, lineHeight(_:), for adjusting the distance between the baselines of two subsequent lines of text. There are a few options available in this new API, so I thought I would look through how they behave in practice: nilcoalescing.com/blog/Adjusti...

The February issue of the Nil Coalescing newsletter is out 📬 It’s been a busy month for our team with lots of travel! I've shared a glimpse into my "Swift's Hidden Gems" talk from the ARCtic Conference, a new SwiftUI post, and plans for the near future. nilcoalescing.com/newsletter/2...

For precise control over which attributes should animate in #SwiftUI, especially in generic components that accept arbitrary content, we can use the animation(_:body:) API introduced in iOS 17 to avoid accidental animations. I've written a post about it: nilcoalescing.com/blog/Isolate...

Last week I had an amazing opportunity to be part of the ARCtic Conference and present a talk on lesser known Swift language features. I really enjoyed the conference and my stay in Lapland ❄️ ☃️ 🦌 Thank you to all the organizers, speakers and attendees!

Yesterday I joined a book club session with iOS developers at Expedia who have been reading SwiftUI Fundamentals (books.nilcoalescing.com/swiftui-fund...). We talked through less obvious parts of SwiftUI, and they shared very positive feedback about the book. Made writing it feel worthwhile 😊

The January issue of the Nil Coalescing newsletter has been sent out and is now available online! I shared some insights from iOS Conf SG, the main ideas from my own talk on building a SwiftUI mindset, and also a few learnings from other talks: nilcoalescing.com/newsletter/2... #iOSDev #SwiftUI

I had a great time at iOS Conf SG last week! I really enjoyed chatting with developers in the iOS community, learning from other speakers, and sharing my SwiftUI talk. Big thank you to all the organizers and volunteers for such a great conference experience 🤩 #iOSConfSG

Swift’s string interpolation system is more powerful than it first appears. Beyond simple value substitution, it can be extended to apply custom logic when values are interpolated. I’ve published a post showing how it can be done: nilcoalescing.com/blog/Definin... #SwiftLang
