SwiftUI toolbars are getting a vocabulary for the thing we’ve all been faking: what matters when space runs out. visibilityPriority, ToolbarOverflowMenu, pinned trailing items, and minimization behavior give us knobs instead of hoping the framework guesses our hierarchy of actions correctly.

A nice little Swift Charts recipe inspired by the iOS Weather UV chart: gradient area, matching line, current-time marker, and a dimming layer over the part of the day that has already passed. The technique is useful because it’s not just prettier data, it tells the user what’s behind them and what’s still ahead at a glance.

A plant identifier is a nice excuse to see Foundation Models image attachments doing something concrete: pass an image, generate a structured plant name, then keep the conversation going with follow-up questions.

SwiftUI views rendered as Final Cut Pro effects is the sort of sentence that makes you stop and check you read it right.

SQLiteData feels like SwiftData for teams who still want the database to be real. You get familiar wrappers like @table@mastodon.social, @FetchAll, and @FetchOne, but underneath it’s SQLite, GRDB, type-safe queries, and CloudKit sync without pretending schema design doesn’t exist.

The foldable iPhone conversation is no longer just gadget gossip; it’s a layout problem with a hinge in the middle of it. The useful bits here are practical: trust size classes over device assumptions, test asymmetric safe areas, let system containers manage bars, and don’t hide core features behind some cute folded pose.

Swift Charts can build a proper sunburst diagram, but the fun is in the details: SectorMark rings, radius ratios, angular insets, grouped data layout, and accessibility labels that don’t get treated as an afterthought.

What if the patterns you rely on in SwiftUI are actually working against the framework? This talk covers five key principles with practical examples of common patterns and anti-patterns - helping you build more predictable, performant, and maintainable UIs.

Building your own CMS is the best way to understand the full stack. CTSiteBuilder is a macOS app using SQLiteData, CloudKit, and SwiftUI to manage content and deploy a static site via rsync — with Markdown support included.

Ever tried interpolating an SF Symbol Image directly into a SwiftUI Text view and had it fail silently? This guide explains why it only works in localized strings and shows the correct approaches for embedding symbols in text.

Most accessibility testing requires real devices, but Xcode previews offer more than you might think. Canvas variants for dynamic types, #Preview traits for landscape, .dynamicTypeSize() and .preferredColorScheme(.dark) modifiers, plus environment variables for legibility and locale.

RCS has been easy to ignore if most of your world lives inside iMessage, but cross-platform messaging is finally less awful on iPhone. The real-world test here — texting friends in Germany for a month and checking whether it stayed free — is more useful than another feature checklist.

Swift Testing is settling in as the default path, and the migration story is getting clearer: @Test@mastodon.social, #expect, #require, parameterized tests, attachments, and exit tests where the platform allows them.

The little UIViewRepresentable WebView wrapper we’ve all copied between projects can start packing its bags. iOS 26 gives SwiftUI a native WebView, and WebPage covers the bits real apps need: title, loading state, progress, history, secure-content state, and async JavaScript.

Swift’s August roundup is very much a “look how far outside Xcode this language is wandering now” moment. Elementary and ElementaryUI push Swift deeper into web UI work, SwiftTUI brings state and animation ideas into terminal apps, and the Windows story keeps getting less theoretical.

Apple’s guide lays out the official path for getting AppEntity types into Spotlight, with IndexedEntity doing a lot of the connective work. The big bit for our codebase is that Spotlight is no longer just a bag of searchable strings; it can carry structured app entities that Siri and other system experiences can reason about.

Foundation Models get much more real once the prompt can include an image, and the plate-scanner example makes the point without overcooking it. Define a Generable result type, pass instructions plus an Attachment into LanguageModelSession, and get structured output back that the UI can actually use.
