I've been experimenting with the new SwiftUI APIs for reordering items in container views and drag-and-drop in iOS 27. I documented what I've learned in my new blog post: nilcoalescing.com/blog/NewSwif...

Last day of the sale!

Use the AttributedString API to build a reusable Text initializer that applies a distinct font to the unit component of a formatted measurement: nilcoalescing.com/blog/Styling... #SwiftUI #iOSDev

New in iOS 27: SwiftUI now includes CrossFadeNavigationTransition, a built-in cross-fade navigation transition, and AnyNavigationTransition, a type-erased wrapper that allows transitions to be selected dynamically at runtime. #iOSDev #SwiftUI nilcoalescing.com/blog/SwiftUI...

I've built a macOS app for designing mesh gradients. Tintly generates gradients from pasted color palettes and lets you adjust control points visually. It can export images, SVGs, CSS, and SwiftUI code. It's now available on the Mac App Store: apps.apple.com/us/app/tintl... #macOSDev #IndieDev

I wrote about two additions to SwiftUI's navigation transition APIs in iOS 27. The new crossFade transition provides an alternative presentation animation, while AnyNavigationTransition makes it possible to choose a transition dynamically at runtime: nilcoalescing.com/blog/SwiftUI...

I've just released an update for @brevecoffeeapp.bsky.social! It adds Home Screen widgets with daily coffee suggestions, recipe sharing, improved search, and better VoiceOver support ☕️

Breve v1.2 is now live! You can now get daily coffee suggestions right on your Home Screen with the new widgets and share your favorite coffee recipes from the app with friends! Get it on the App Store: apps.apple.com/us/app/breve... #iOSDev #IndieDev #Coffee

Learn the recommended ways to initialize and store Observable classes in SwiftUI views, and see what can go wrong when observable state is managed incorrectly: nilcoalescing.com/blog/Initial...

In iOS 27 we can add swipe actions to items in any scroll container, not just List, by applying the new swipeActionsContainer() modifier to the wrapping ScrollView. I wrote a post with some examples: nilcoalescing.com/blog/CustomS... #WWDC26 #iOSDev #SwiftUI

In Xcode 27 @State changes from a property wrapper to a macro, gaining lazy evaluation of the initial value. I summarized what this means for managing @Observable classes in our SwiftUI views: nilcoalescing.com/blog/Initial... #WWDC26 #SwiftUI #iOSDev

Add symbol effect animations and transitions to symbol images in SwiftUI to handle icon state changes without custom drawing or animation logic: nilcoalescing.com/blog/Animati...

For a new app I'm working on, I needed to display a measurement in a SwiftUI Text view with the unit in a smaller font than the value. We can do this by targeting the unit component in an AttributedString. I shared an example on my blog: nilcoalescing.com/blog/Styling...

Review the full range of animation timing options available in SwiftUI, including easing curves, spring animations, the CustomAnimation protocol, and animation modifiers: nilcoalescing.com/blog/Animati...

While building and testing a macOS app locally, values stored in UserDefaults remain between launches. We can quickly clear them using the defaults delete command. I wrote a short post as a reference: nilcoalescing.com/blog/Clearin... #macOSDev

Build SwiftUI views that update periodically or continuously, without relying on explicit state changes, to create dynamic interfaces and visual effects: nilcoalescing.com/blog/Timelin... #iOSDev #SwiftUI

The May issue of the Nil Coalescing newsletter is out! I shared Apple's community recognition page, some observations from using AI agents with SwiftUI, recent blog posts, and a bit of pre-WWDC excitement: nilcoalescing.com/newsletter/2...

Master programmatic scroll control in SwiftUI using defaultScrollAnchor(_:), scrollPosition(_:anchor:), and ScrollPosition to configure, drive, and read scroll position in your apps: nilcoalescing.com/blog/ModernS... #iOSDev #SwiftUI

When we need to compare arrays based on custom criteria in Swift, we can use the elementsEqual(_:by:) method. It allows us to define custom comparison logic with a closure, offering more flexibility than using the == operator: nilcoalescing.com/blog/Compare... #SwiftLang

I wrote a new post about TimelineView in SwiftUI and how it can be used to build views that update periodically or continuously without relying on explicit state changes, making it possible to create dynamic interfaces and visual effects: nilcoalescing.com/blog/Timelin... #iOSDev #SwiftUI

SwiftUI’s resizable sheet APIs let us present half sheets, define custom detents, and control sheet behavior across different device configurations: nilcoalescing.com/blog/Resizab... #iOSDev #SwiftUI

To sort an array based on a particular property in Swift, we can use the KeyPathComparator API from Foundation in combination with sorted(using:) method: nilcoalescing.com/blog/SortEle... #SwiftLang

To programmatically scroll to an edge, a raw offset, or a view with a provided identity in SwiftUI, we can use the scrollPosition(_:anchor:) modifier. It takes a binding to a ScrollPosition, available from iOS 18: nilcoalescing.com/blog/ModernS... #iOSDev #SwiftUI

BackgroundStyle in SwiftUI exposes hierarchical levels via .secondary, .tertiary, and similar properties, giving us system background colors that adapt to context and color scheme without the need to bridge through UIColor: nilcoalescing.com/blog/Hierarc... #iOSDev #SwiftUI

We can customize where the scroll view should initially position its content in SwiftUI using the defaultScrollAnchor() modifier. It also lets us set a different anchor per situation, for example when the content is smaller than its container: nilcoalescing.com/blog/ModernS... #iOSDev #SwiftUI

Sorting arrays in Swift can be made more concise and readable by using comparison operators as closures in the sorted(by:) method: nilcoalescing.com/blog/Sorting... #SwiftLang

I've just published a post covering the modern SwiftUI APIs for programmatic scrolling, including defaultScrollAnchor(), scrollPosition(), and others, also highlighting some nuances that are easy to miss: nilcoalescing.com/blog/ModernS... #iOSDev #SwiftUI

Customize the appearance of the macOS window toolbar in SwiftUI using scene and view modifiers to control its layout, title visibility, and background: nilcoalescing.com/blog/AGuideT... #macOSDev #SwiftUI

AI coding agents tend to hardcode spacing in SwiftUI, which can look wrong and cramped when a user adjusts their font size preference. SwiftUI's default container spacing adjusts for Dynamic Type automatically, but if you need custom spacing, consider using the ScaledMetric API. #iOSDev #SwiftUI
