Starting with iOS 27, we can actually convert a tab bar to a sidebar. A new modifier was introduced to do this. “.defaultTabBarPlacement(.sidebar)” As of current testing, this seems to work on iPhones as well when the app is in landscape mode. This is the same behavior used in the iPhone Health app, where the tab bar converts into a sidebar in landscape mode!

We've got this incredible feature on the BBC through the World Cup. For games the BBC cover, you can watch the games live (or back) in this 3D space, freely controlling the camera angle or viewing it in first person from any players' POV. Top for tactical insight. See here: 3d-bbc.co.uk/

Finding Beta features in Apple's docs is always a scavenger hunt. 😅 Luckily, Itsuki made a little app to solve this, strictly fetching the Beta documentations so you don't miss out on any hidden #WWDC26 gems.

Today we’re launching Ask DoorDash — a new conversational way to search the app in your own words through chat, voice, a recipe link or photo. Ask DoorDash can build you a grocery cart ~5x faster than doing it manually. It takes a single prompt to complete your cart in under 2 minutes. In early testing, nearly half of all restaurant orders made with Ask DoorDash were from a place the customer had never ordered from before, and grocery baskets built with Ask DoorDash were over 35% larger than those without.

I've been meeting with developers who use FlowDeck daily to understand their workflows and how they use the tool. Some findings are already shaping what's coming next. If you're on FlowDeck daily and have 20 minutes for a Zoom coffee, DM me.

Apple finally did it. Its new framework, Core AI, runs models entirely on Apple silicon, so inference happens on the user's device with zero server calls and zero token bills. That means Qwen, Mistral, and SAM3 running natively across iPhone, iPad, Mac, and Vision Pro. It's a memory-safe Swift API that compiles models ahead of time for near-instant load. Pulling one in takes a few lines: let segmenter = try await ImageSegmenter(resourcesAt: sam3ModelURL) let response = try await segmenter.segment(image: inputImage, prompt: "flower") The launch goes beyond the runtime, though. It ships curated open models packaged for Swift, PyTorch extensions to convert your own, and an optimizer that shrinks models layer by layer with minimal accuracy loss. There's also a macOS debugger that profiles performance and traces behavior back to your original Python, plus Xcode tools to validate models before they ship. For any team that wanted real on-device AI without a cloud bill attached to every user, this is the answer. Models repo: github.com/apple/coreai-mode…

SwiftUI’s new type-checking enhancements (`@ContentBuilder`) and lazy `@State` are the culmination of literally years of careful effort behind the scenes to solve some of the biggest everyday pain points in SwiftUI development. At this point, there are millions of lines of SwiftUI result builder and state code shipping in production. With these changes, every one of those lines of code will suddenly compile differently, improving both compilation and runtime performance, and most developers *will never even notice*. That doesn’t normally happen. Maintaining binary, source, and backwards compatibility across releases imposes strict limitations on how SDK APIs can evolve. If you think of a better way to compile some library DSL syntax after shipping it publicly, you’re usually out of luck. These enhancements were only possible because of dedicated engineers on the Swift and SwiftUI teams working closely together, sweating the subtlest of details, and persevering through countless dead-end experiments and fraught internal deployments. Their reward? That future developers will *not* see some type-check error or performance hitch, and will *never* have to know that it ever worked any differently. But that’s wonderful. We love it. The joy is in the doing. Thank you @slazaruseth, @daniel_duan, @hollyborla, Pavel Yaskevich, and others from the Swift and SwiftUI teams for getting these enhancements over the finish line! (I’m no longer at Apple but can’t help but brag about these talented people 👏🏻)

Proud to share a feature we've been working hard on! In Xcode 27.0, Agentic Xcode can automatically find runtime bugs for you. After a code change, it installs the app in a simulator, navigates your UI, observes the screen and validates that the feature works flawlessly ... (1/2)

Only 7 onchain neobanks hit a new weekly ATH in volume last week Plasma One, EtherFi, RedotPay, Slash, Whop, KAST and Karta The projects tracked by Paymentscan accounted for nearly $187.7M in weekly volume, or 91.1% of the market This isn’t a coincidence Which card did you use the most last week?
