Podkey WWDC 2026

A Podkey summary of Profile, fix, and verify: Improve app responsiveness with Instruments , from WWDC 2026. A lot of this episode comes down to one very practical lesson: the first tool that seems to explain a slowdown is not always telling the whole story. The big themes here are how to read Instruments more accurately, how a Swift runtime detail can quietly eat CPU, and how to catch main-thread...

A Podkey summary of Refine accessibility for custom controls , from WWDC 2026. Today’s thread is accessibility, but in a very practical, hands-on way: how custom controls actually become usable with VoiceOver and other assistive tools. The big idea is pretty simple once you hear it. If a control has a purpose, a current value, some available actions, and clear feedback, that needs to be exposed ju...

A Podkey summary of Read between the strokes with PencilKit , from WWDC 2026. This one is a pretty meaningful PencilKit update, especially if you care about handwriting, search, or building anything more ambitious than a simple sketch pad. Apple’s adding on-device handwriting recognition in 29 languages, better ways to search and index handwritten notes, cleaner stroke identity and selection hooks...

A Podkey summary of Principles of great design , from WWDC 2026. Today’s thread is design with a point of view: what belongs, what really doesn’t, and how every choice asks for a little bit of a user’s time, attention, and trust. A lot of this comes down to making products feel clear, safe, and human, especially once AI gets involved and the stakes get a little weirder. And underneath all of it, t...

A Podkey summary of Prepare your tvOS apps for Dynamic Type , from WWDC 2026. A nice little accessibility upgrade is coming to Apple TV apps with tvOS 27: system-wide Large Text support. The big idea is simple. Text should scale the way people need it to, and now developers also have a clearer way to show in the App Store that their apps actually support that. A lot of this comes down to avoiding...

A Podkey summary of Migrate to Swift Testing , from WWDC 2026. Swift Testing is getting a lot more practical, especially for teams that still have a pile of XCTest around. The big story here is interoperability: you can mix the two frameworks, control how loudly cross-framework problems get reported, and migrate bit by bit instead of stopping everything for a giant rewrite. On top of that, Swift T...

A Podkey summary of Modernize your AppKit app , from WWDC 2026. A lot of the AppKit guidance coming into focus right now is really about letting the framework do more of the work. The big theme is moving away from hand-rolled mouse tracking and one-off event code, and toward gesture recognizers, control events, delegate callbacks, and state restoration that all play nicely with SwiftUI and UIKit-s...

A Podkey summary of Offer subscriptions to groups and organizations , from WWDC 2026. Apple’s adding a more grown-up way to sell subscriptions to teams, classrooms, and companies, and it changes both the buying flow and the pricing math. The big pieces are group purchases inside an app, large-scale buying through Apple Business Manager and Apple School Manager, and new bulk discount pricing that g...

A Podkey summary of Meet the new MetricKit , from WWDC 2026. Apple gave MetricKit a pretty major overhaul in iOS 27, and this one matters if you care about app performance in the real world, not just in a lab. The big shift is a Swift-first API, richer diagnostics, and a new way to tie performance data to what the app was actually doing at the time. So instead of just seeing that something was slo...

A Podkey summary of Optimize custom machine learning operations with Metal tensors , from WWDC 2026. A lot of this week’s Apple graphics and AI story really comes down to one idea: getting more model work closer to the hardware, with less fuss for developers. The big pieces are the M5’s new neural accelerator inside each shader core, broader quantized tensor support in TensorOps, and a pretty prac...

A Podkey summary of Modernize your UIKit app , from WWDC 2026. A lot of the latest iOS 27 app changes really point in one direction: apps need to stop thinking in fixed screens and start thinking in flexible scenes. That affects launch behavior, layout, navigation, even how Siri can interact with what’s on screen. And Apple’s also giving developers a pretty practical assist here, with automatic tr...

A Podkey summary of Meet Trust Insights , from WWDC 2026. Today’s thread is pretty simple: a lot of fraud now works by manipulating people in real time, and that creates a security problem that passwords, biometrics, and even MFA don’t really solve on their own. The other big piece is Apple’s Trust Insights framework, which is built around that exact gap. It tries to tell the difference between a...

A Podkey summary of Improve your prompts by hill-climbing with Evaluations , from WWDC 2026. Today’s thread is really about one deceptively simple question: how do you know your AI evaluator is actually judging things the way a human would? The big themes are drift between model and expert ratings, a more honest way to measure agreement with Cohen’s kappa, and a very practical process of improving...

A Podkey summary of Make your game great with touch , from WWDC 2026. Apple’s Touch Controller framework feels like one of those tools that can quietly make mobile games a lot better when it’s used well. The big idea is pretty simple: touch input gets treated like a real controller, so developers can plug it into the same logic they already use for gamepads. What stands out is how much of the hard...

A Podkey summary of Meet Core AI , from WWDC 2026. Today’s catch-up is really about what happens when AI moves off the cloud and onto the device in your hand. The big theme is cost, speed, and privacy all getting reshuffled at once, with Apple’s Core AI approach making local inference practical, while developers get better tools for startup time, debugging, and performance tuning. And underneath t...

A Podkey summary of Meet the Music Understanding framework , from WWDC 2026. Today’s story is a pretty interesting one if you care about music apps, editing tools, or just the general direction of privacy-friendly software. Apple’s Music Understanding framework is built to analyze songs entirely on-device, and it’s doing a lot more than guessing a tempo. It can map key changes, beats, structure, p...

A Podkey summary of Get started with the HTML Model Element , from WWDC 2026. This week’s story is really about 3D on the web getting a lot less awkward. The big shift is a native HTML model element, a practical file format in USDZ, and a handful of tools that make building 3D experiences much more realistic for regular developers. And then around that, you’ve got the stuff that makes it usable in...

A Podkey summary of Meet the Evaluations framework , from WWDC 2026. Today’s thread is really about a simple problem with messy consequences: AI features don’t behave like ordinary software, so ordinary testing stops being enough pretty quickly. The big idea here is an Evaluations framework that measures how often an AI system does the right thing, how often it drifts, and how developers can use t...

A Podkey summary of Explore advanced App Intents features for Siri and Apple Intelligence , from WWDC 2026. A lot of the newest Siri and App Intents work comes down to one idea: give the system better context, and it gets a lot more useful. That means better app-specific responses, smarter follow-up questions, cleaner confirmation for risky actions, and a much better shot at understanding what the...

A Podkey summary of Explore immersive website environments in visionOS , from WWDC 2026. This one is a really practical look at how immersive web experiences are starting to feel more like normal web development, just with a lot more spatial weirdness in the best way. The big ideas are familiar APIs, smarter loading so giant 3D assets do not hit everybody by default, and a bunch of small technical...

A Podkey summary of Iterate your spatial scenes faster with Reality Composer Pro 3 , from WWDC 2026. Apple's pushing Reality Composer Pro in a pretty practical direction: less waiting, less guesswork, and a lot more seeing your changes immediately. The big theme across these updates is faster iteration, whether that's previewing straight on Vision Pro, tweaking simulations while they'r...

A Podkey summary of Dive into lazy stacks and scrolling with SwiftUI , from WWDC 2026. Today’s thread is SwiftUI lazy stacks, and a lot of it comes down to one simple fact: lazy stacks are smart, but they’re guessing more often than people realize. That guesswork shows up in scroll position, visibility rules, performance, state, and even whether a view vanishes a little too early. The good news is...

A Podkey summary of LLM search using Core Spotlight , from WWDC 2026. Today is really about one idea: Apple’s Spotlight index is turning into something a language model can use directly, instead of just something a human searches through. The interesting part isn’t only that the model can query your app’s data, it’s how developers can shape that interaction so it stays accurate, efficient, and use...

A Podkey summary of Enhance your presence on the App Store , from WWDC 2026. Apple’s giving developers a lot more control over how their apps show up in the App Store, and it’s a pretty meaningful shift. The big idea is simple: better visuals, faster updates, and more ways to match what people see in search, ads, and product pages with what the app actually offers. For teams trying to stand out, t...

A Podkey summary of Explore enhancements to visionOS object tracking , from WWDC 2026. This update is really about making object tracking feel more usable in the real world. Faster tracking for handheld objects, more reliable training, true metric positioning, and a much more practical path for building spatial accessories all point in the same direction. It also opens the door to bringing the sam...
