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

SwiftUI gives us a lot of control when styling SF Symbols, including custom foreground styles. One simple technique is to apply a foreground style with an inner shadow to make an icon look cut out from its background: nilcoalescing.com/blog/AddAnIn... #SwiftUI #iOSDev

Last day of the sale!

It's not always obvious what is the right way to initialize an Observable within the SwiftUI view hierarchy, and what are the consequences of getting it wrong, so I wrote a blog post exploring some common use cases: nilcoalescing.com/blog/Initial... #iOSDev #SwiftUI

The November issue of the Nil Coalescing newsletter has been sent to all the subscribers, and it's now available online: nilcoalescing.com/newsletter/2... I shared news on my Swift and SwiftUI book updates, Black Friday book deals, recent videos, and my conference plans for next year.

I've published a new video! I shared some tips for implementing Dynamic Type support in SwiftUI apps, covering system and custom fonts, ScaledMetric API, and dynamicTypeSize environment value: youtu.be/wflWj5l7wlk #SwiftUI #iOSDev #Accessibility

I noticed that on iOS 26.1 there are some small improvements to the Liquid Glass tab bar: the selected tab color looks less saturated, making it more readable on top of colorful backgrounds, and the edge effect is stronger. Here is @brevecoffeeapp.bsky.social on iOS 26 and 26.1:

Excited to share my recent appearance on the Swift Academy podcast! In this episode, Walid Sassi and I talk about iOS 26, Liquid Glass, SwiftUI, and Accessibility, and explore some of the new APIs along with ways to make apps more inclusive: youtu.be/CEZbwcv60MA #iOSDev #SwiftUI

The October issue of the Nil Coalescing newsletter has gone out to all subscribers 📬 I've shared news on my SwiftUI Fundamentals book update, and my recent technical learnings on supporting iOS 26 and 26.1. You can also read the issue online: nilcoalescing.com/newsletter/2...

I've been exploring SwiftUI APIs for customizing scroll behavior, including paging and view-aligned snapping, and wrote a post sharing what I learned and what to watch out for to avoid unexpected results: nilcoalescing.com/blog/ScrollV... #SwiftUI #iOSDev

Halloween has arrived in Breve! Discover limited-time coffee recipes brewed with a little magic and a lot of flavor 🎃✨ Breve on the App Store: apps.apple.com/app/apple-st... #CoffeeLovers #Halloween #iOSApp

"SwiftUI Fundamentals" by @natpanferova.bsky.social has been updated for iOS 26 with refreshed visuals and examples reflecting the new Liquid Glass design: nilcoalescing.com/blog/SwiftUI... #SwiftUI #iOSDev

SwiftUI makes it easy to show a “no results” state for search with ContentUnavailableView.search. And it even automatically includes the search text in the message, as long as it’s used within the scope of the searchable() modifier. #iOSDev #SwiftUI

I’ve just published an update for my SwiftUI Fundamentals book! It’s now refreshed for iOS 26 and the new Liquid Glass design, with updated examples and screenshots throughout. You can check it out and get the new version here: books.nilcoalescing.com/swiftui-fund... #iOSDev #SwiftUI

Buttons inside a SwiftUI List row can cause the entire row to become tappable and trigger multiple buttons at once, but applying a specific button style ensures each button works independently: nilcoalescing.com/blog/Multipl... #SwiftUI #iOSDev

Discover how to use the Observable macro in SwiftUI and its advantages over ObservableObject, such as more efficient view updates and simplified code management: nilcoalescing.com/blog/Observa... #SwiftUI #iOSDev

In the first version of @brevecoffeeapp.bsky.social I placed timers in the tab view's bottom accessory, but it broke in iOS 26.1 beta. In the latest release, I switched to a custom view with an interactive glass effect. To keep it always visible above the tabs, I used safeAreaBar(). #SwiftUI #iOSDev

I noticed that on iOS 26, the default swipe action appearance changed to show both an icon and a title instead of just the icon. If we want to restore the previous icon-only look, we can use the labelStyle() modifier in SwiftUI: nilcoalescing.com/blog/ShowIco... #iOSDev #SwiftUI

When testing Dynamic Type support in @brevecoffeeapp.bsky.social I noticed that text would get truncated at larger text sizes for no real reason. I had to apply fixedSize(horizontal:vertical:) as a workaround to force the text to wrap instead: nilcoalescing.com/blog/Avoidin... #SwiftUI #iOSDev

Format interpolated values like arrays of strings, measurements, and dates directly inside SwiftUI Text views using FormatStyle, and display dynamic dates using Text.DateStyle: nilcoalescing.com/blog/Formatt... #SwiftUI #iOSDev #SwiftLang
