I've been following WWDC since 2011* and over the years I've developed my own process for watching sessions. Over the past 15 years, I've gone through all the stages from denial (I missed all the videos, for example, in 2014, when I couldn't accept Swift's appearance), to bargaining ("I still CAN watch all of them!") and finally accepting and creating my own approach to watching WWDC. So here's my current approach: I try to watch Keynote and Platforms State of the Union at the time of their live broadcast or in the early days. When all the sessions become available, I sit down and go through all the titles and descriptions and choose what I will watch. All sessions fall into 4 categories: Essential is a must watch and should never be missed Nice To Watch is something interesting to me personally and may be applicable to what I work with Only If I Have Time is for optional sessions that interested me, but if I skip them, then nothing terrible will happen Everything else Thus, I clearly identify a fairly small set of sessions that I definitely need to watch, usually it's about 10 sessions and I don't feel any FOMO or pressure that there is so much new and how and when to watch it all. Most of the time, it takes me all summer to slowly watch everything from Essential, a few (or all, it depends) Nice To Watch, and sometimes a couple, and sometimes nothing at all from Only If I Have Time. An important rule for me is to watch Essential first. Then I can do whatever I want. Another personal kink of mine is to watch the sessions in the order of their numbering. For example, in my Essential category, the very first video is 227. Create UI prototypes using agents in Xcode , and then 258. What’s new in Xcode 27 and so on. So, here is my personal list of WWDC’26 sessions, divided into these categories: Essential Create UI prototypes using agents in Xcode What’s new in Xcode 27 Xcode, agents and you Get the most out of Device Hub What’s new in Swift What’s new in SwiftUI Moderni

Apple says it won't limit the capabilities of devices leased through its new Upgrade program if you miss a payment.

Accessibility has become personal for me. I am getting older, and large type is no longer an abstract preference somebody else needs. It is how I read a phone comfortably. What is Codename One? Codename One is an open-source framework for building native iOS, Android, desktop, and web apps from a single Java or Kotlin codebase. Learn more at codenameone.com . I worked with accessibility experts at Sun Microsystems and learned how deep the problem goes. A label is the easy part. Real accessibility needs roles, values, ranges, actions, traversal order, live announcements, collections, focus, platform conventions, and a way to test all of it. That complexity is why full Codename One accessibility support sat dormant for a decade. We eventually added setAccessibilityText() . It was useful, but it was the poor man's version. PR #5363 replaces that single-label model with a portable semantics tree we can be proud of. Lightweight UI needs a second tree Codename One paints lightweight components into its own native surface. VoiceOver cannot inspect a Button as a UIKit button because there is no UIKit button there. TalkBack cannot walk an Android View hierarchy because most of the painted controls are not Android views. The new accessibility manager builds an immutable virtual tree beside the visual component tree. Standard controls infer their semantics. Custom controls can replace or extend them. Each port exposes that virtual tree through the platform accessibility API. The visual and semantic hierarchies can differ. A card made from five labels might need to read as one item. A chart may paint 200 points from one component, but expose each meaningful point as a virtual child. A renderer-backed list can expose stable rows even though those rows are not component instances. Standard components work without annotations Buttons, checkboxes, radio buttons, sliders, text fields, lists, tables, tabs, labels, dialogs, and containers infer their normal roles, values, states, and

Widget support was one of the earliest Codename One requests. We dismissed it for years because a widget must render while the application UI is not running. A normal Codename One Component needs the application renderer, event dispatch thread, and live object graph. A home-screen widget gets none of those. What is Codename One? Codename One is an open-source framework for building native iOS, Android, desktop, and web apps from a single Java or Kotlin codebase. Learn more at codenameone.com . The missing piece had been under our nose for a decade. Steve added background processes so an app could refresh data without showing its UI. That solves the update side. The rendering side becomes possible once the widget is data rather than a live component. PR #5365 turns that observation into com.codename1.surfaces , one API for home-screen widgets, Live Activities, Dynamic Island, Android ongoing notifications, and desktop floating widgets. The dead-process rule An external surface is a piece of application state that the operating system can render outside the app. The app publishes a serializable layout and a timeline of state maps. The platform persists that data, then renders it with its own surface technology. You cannot attach a Java listener to a widget. There may be no Java process to invoke. You assign a string action ID instead. A tap launches the app and delivers that action after startup. The simulator implements the same model. Open Widgets > Widgets Preview to inspect every registered kind, move through its timeline, change size and appearance, and click actions without creating a device build. Widget kinds exist at build time iOS and Android compile widget galleries into the native application. The kinds must therefore be known during the build. Add a surfaces.json resource: { "liveActivities" : true , "kinds" : [ { "id" : "delivery_status" , "name" : "Delivery" , "description" : "Track your order" , "iosFamilies" : [ "systemSmall" , "systemMedium" ] } ] }

Codename One Settings used to be a screen inside the old GUI Builder jar. It edited project properties, managed accounts, opened signing workflows, monitored builds, installed extensions, and accumulated every job that did not have a better home. What is Codename One? Codename One is an open-source framework for building native iOS, Android, desktop, and web apps from a single Java or Kotlin codebase. Learn more at codenameone.com . PR #5359 replaces it with a standalone Codename One desktop application. It does fewer things, which is the point. One command, one project Run the new tool from a Codename One Maven project: mvn cn1:settings The Maven plugin resolves the com.codenameone:codenameone-settings artifact, launches it against the current project, and writes changes back to that project's codenameone_settings.properties and Maven configuration. The tool has its own release lifecycle instead of borrowing the GUI Builder's jar and version. This is the new Basic screen. It keeps the properties that belong to the source project: display name, package name, version, main class, icon, and related build choices. Build hints are searchable project data Build hints used to feel like an untyped text file with a dialog in front of it. The new editor preserves direct key-value control, but adds descriptions, known value types, filtering, and a focused editing flow. Nothing prevents you from editing the property file by hand. The Settings tool is useful when you do not remember whether the current spelling is ios.themeMode , and.themeMode , or a platform-specific signing key. It also keeps project values visible without mixing them with account state from the cloud. For example, selecting the modern native themes still produces ordinary project settings: nativeTheme = modern ios.themeMode = modern and.themeMode = modern The file remains the source of truth. The UI is an editor, not a second configuration system. Extensions keep compatibility warnings The Extensions screen

An iOS or Android update can change a screen you shipped without you changing a line of code. If your app builds its UI from UIKit, SwiftUI, Compose, or Material widgets, Apple or Google owns those widget implementations. Codename One does something different. It statically links our lightweight component implementation into your native app. The UI you test is the UI your users keep after the next OS update. An update can still break a platform API or permission contract, but it cannot swap our button implementation for a new one. What is Codename One? Codename One is an open-source framework for building native iOS, Android, desktop, and web apps from a single Java or Kotlin codebase. Learn more at codenameone.com . Lightweight does not mean a Java paint loop limping behind the platform. On iOS, components paint through our Metal pipeline. The moving Liquid Glass tab lens in this post is a Metal shader on the frame's existing command buffer, with no transfer of pixels back to the CPU. At the same time, last week's ParparVM work brought our ahead-of-time VM to geomean parity with warmed Java 25 across ten benchmarks. Six finished at or ahead of HotSpot. The tradeoff is that our UI does not inherit Apple's or Google's latest redesign for free. We have to study it, reproduce the parts that make sense, and test the result. That is work we take on so you can work on your app instead of working for the Apple and Google design teams. You decide when your app adopts a new look. The OS does not decide for you on upgrade day. The ParparVM and theme-fidelity branches ran in parallel. We wanted them in the same release, but each became too large to merge together safely. The fidelity work took longer. PR #5274 alone reports 53,000 additions across 1,147 changed files. Generated access registries, resources, screenshots, and native goldens account for much of that number, but the scale is still real. Five follow-up PRs fixed what the first pass exposed. Owning the component sta

In the age of "Cloud Everything," our most sensitive data—our heartbeat, our sleep cycles, our stress levels—often ends up on a server somewhere in Northern Virginia. But what if we could keep that data where it belongs? On your device. Today, we're diving deep into Edge AI and On-device LLMs . We will build a privacy-centric health coach that uses MLX-Swift to run Llama-3 directly on your iPhone's Apple Silicon. We’ll be pulling real-time Heart Rate Variability (HRV) data from the HealthKit API and generating semantic health summaries without a single byte ever leaving your phone. 🚀 Why Edge AI? 🛡️ When dealing with Private AI and sensitive medical metrics, the "Cloud-First" approach is a liability. By leveraging MLX-Swift and the Unified Memory Architecture of the A17 Pro/A18 chips, we achieve: Zero Latency : No round-trip to a server. Total Privacy : Your data stays in the Secure Enclave. Offline Capability : Health insights in the middle of the woods? Yes. The Architecture 🏗️ The data flow is simple but powerful. We fetch raw samples from HealthKit, preprocess them into a prompt-friendly format, and feed them into a quantized Llama-3 model managed by the MLX framework. graph TD A[iPhone HealthKit Store] -->|Fetch HRV Samples| B(Swift Data Controller) B -->|Normalize & Format| C{MLX-Swift Engine} D[Llama-3-8B-4bit Model] -->|Load Weights| C C -->|Local Inference| E[Neural Engine / GPU] E -->|Semantic Summary| F[SwiftUI Dashboard] F -->|User Feedback| A Prerequisites 🛠️ To follow this advanced tutorial, you'll need: Xcode 15.4+ and a physical iPhone (iPhone 15 Pro or newer recommended for 8GB+ RAM).

If you ship a React Native / Expo app to the App Store, you know the ritual. Open the Apple Developer portal, create a bundle identifier, tick the capability checkboxes, generate a provisioning profile, pick the right certificate. Then hop over to the Expo dashboard, create the EAS app, wire up credentials, add your environment variables one screen at a time. It works, until you have to do it again for a second app, or a second environment, or a teammate needs to know why a capability is enabled. None of it is written down. It drifts. And the usual mobile tooling doesn't help much here: fastlane and the EAS CLI are great, but they're imperative — scripts that do things — not a declarative description of what your release setup should be . That's the gap these two providers fill: elevenode/appstore — App Store Connect: bundle identifiers, provisioning profiles, certificates. elevenode/expo — Expo Application Services (EAS): apps, credentials, environment variables, update channels. Both are open source (Apache 2.0) and published on the Terraform Registry. Let's use them together to describe a mobile app's release setup as code. What you'll need Terraform (or OpenTofu) An App Store Connect API key (Users and Access → Integrations → App Store Connect API): the key, its key ID, and your issuer ID An Expo access token (expo.dev → account settings → Access Tokens) and your Expo account name Export the credentials as environment variables so nothing sensitive lands in your config: export APPSTORE_KEY = " $( cat AuthKey_XXXX.p8 ) " export APPSTORE_KEY_ID = "XXXXXXXXXX" export APPSTORE_KEY_ISSUER_ID = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" export EXPO_TOKEN = "your-expo-access-token" export EXPO_ACCOUNT_NAME = "your-account-name" Wiring up both providers terraform { required_providers { appstore = { source = "elevenode/appstore" } expo = { source = "elevenode/expo" } } } # Reads APPSTORE_KEY / APPSTORE_KEY_ID / APPSTORE_KEY_ISSUER_ID from the env. provider "appstore" {} # Re

I cranked Apple’s iOS 27 beta to maximum transparency on my iPhone and enjoyed every warped second.

Code found in an iOS 27 beta would allow Apple to put a financed iPhone in "Restricted Mode" if it detects any missed payments, 9to5Mac reports. The finding follows a story from Bloomberg earlier this week claiming Apple is preparing to launch a new "Apple Upgrade" financing program for leasing new devices. iPhones in "Restricted […]

A mobile user taps a button. Nothing opens. There is no validation message, exception, or visible loading state. The control simply appears dead. These bugs are frustrating because the visible symptom is tiny while the real interaction crosses several technical boundaries. I recently investigated this kind of failure in a Blazor Hybrid image workflow. The feature behaved sensibly in a desktop browser, but the same interaction did not reliably open the photo picker inside an iOS WebView. The useful lesson was broader than the eventual CSS change: A native capability launched from hybrid web UI is a cross-layer contract, not a single component event. To make the interaction dependable, the browser gesture, responsive dialog, native application metadata, and automated tests all had to agree. The visible button was not the real control Styled file-upload controls commonly hide the browser's native file input. A label or custom button receives the click and forwards it to the hidden input. That pattern can work well on desktop browsers. It provides visual freedom while retaining a native file-selection control underneath. The implementation I examined had taken the hiding quite far: the real input was clipped to a tiny area, while a separate visible element acted as its proxy. On desktop, the browser carried the user action through that indirection. Inside the iOS WebView, the picker did not open. This matters because browsers deliberately protect privileged actions. File pickers, cameras, pop-ups, clipboards, and media playback often require a trusted user activation. The further the real privileged element is removed from the original tap, the more likely platform differences become visible. The fix was conceptually simple: make the transparent file input span the visible button. The control still looks custom, but the user's tap now lands directly on the input that owns the privileged action. The input is visually transparent, not functionally absent. One repaired lay

I'm the developer of DeviceShelf, a local-first network scanner for desktop, mobile and a headless server edition. Until this week the iOS app only existed on TestFlight. Apple has now approved version 1.3.0, so for the first time you can get it straight from the App Store: DeviceShelf on the App Store . What the app does on a phone The iOS app is not a companion viewer. It runs the same scanning engine as the desktop version: it scans the network you're on, identifies devices (vendor, type, OS fingerprint), shows open ports per device, builds a security report, and raises presence alerts when devices appear or drop off. You can export and share results from the phone. The multicast entitlement iOS restricts multicast traffic for ordinary apps, and SSDP/UPnP discovery depends on it. Apple grants the multicast entitlement on request, and DeviceShelf's App Store build has it. In practice, UPnP/SSDP devices show up in scans on the phone the same way they do on desktop. Licensing The download is free and comes with a trial. Full features unlock in one of two ways: activate a DeviceShelf license, which covers desktop, mobile and the server edition with a single purchase, or use the in-app purchase upgrade on iOS. Pricing is on the website if you want the details. Local-first, on mobile too Scans stay on the device. There is no cloud account, and the AI-assisted device identification is bring-your-own-key; no key is bundled or required. The app is still young, and a phone is an unforgiving place for a network scanner. If it mislabels a device on your network or misses one entirely, I'd genuinely like to hear about it.

Okay. This one is going to feel weird at first. I'm going to warn you in advance so you don't think...

The de-extinction startup is looking to double or triple its previous valuation, according to the report.

Adobe's Project Indigo can now remove all kinds of backgrounds from photos you snap using the app

"Something's coming. Something we may not be able to deter."

A helpful comment on my EXIF test suggested using a metadata scrubber. That is useful for ordinary still images, but a mobile upload contract must define every asset it sends. An iOS Live Photo can include both a photo resource and a paired video resource. The failure case is simple: the JPEG derivative has no GPS EXIF, while metadata or an original file associated with the paired video survives in the upload or retry path. Build the resource inventory first: let resources = PHAssetResource . assetResources ( for : asset ) for resource in resources { print ( resource . type , resource . originalFilename ) } Then make privacy assertions per output, not per UI selection: Artifact Required check still derivative no EXIF GPS/location fields paired video derivative no location metadata upload manifest only derived filenames retry queue no path to original resources temporary directory deleted after success or cancellation My lifecycle test would start an upload, force the app into the background after the still image is prepared, kill it while the paired video is processing, and relaunch. Recovery must either regenerate both safe derivatives or delete the incomplete pair. It must never mix a scrubbed still with an original video. Apple’s PHAssetResource API exposes the resources associated with a Photos asset. That enumeration should become evidence in the test: fail when an unexpected resource type is present rather than silently uploading it. Also verify what reaches the server. Device-side inspection alone misses multipart manifests, queued originals, and server-generated previews. Download the stored pair in a test environment and run the same metadata assertions again. A “remove location” button needs a precise scope. For Live Photos, the user reasonably expects it to cover the complete paired asset and every retry copy—not just the JPEG they can see.
