Apple's biggest event of the year is nearly here. The company's Worldwide Developers Conference will spotlight updates to iOS, macOS, and all of Apple's other operating systems, and this year's event could also include a major overhaul for Siri. Here's how you can watch along live. When WWDC will happen and where you can watch […]

Let me start with a confession: I have been writing concurrent code since the only tool in the box was a mutex and a prayer. After a decade of Swift I feel suspicion of any code that touches two threads and claims to be fine. So when Swift 6 showed up promising to prove my concurrency correct at compile time, I had two reactions at once. The grizzled half of me said "sure, kid." The other half — the half that has spent actual weekends chasing a heisenbug that only reproduced on a customer's M1 under sync load — said "...please. Please be real." This is the story of moving Ditto Edge Studio — a SwiftUI debug-and-query tool for the Ditto edge database — to Swift 6's strict concurrency mode. It's a real app: SQLCipher persistence, an embedded MCP server, a SpriteKit presence graph, live sync over Bluetooth and WebSocket. Not a to-do list. The kind of app where concurrency bugs hide in the cracks and wait for a demo. Spoiler: it was worth it. It was also more work than the WWDC talk implied, and the most valuable thing the compiler did happened in the one place I told it to stop looking. Let me show you. First, the Wall: A Dependency That Wasn't Coming to Swift 6 Here's the thing nobody warns you about. Swift 6 language mode isn't really a per-file setting. Your code can be immaculate — every actor isolated, every Sendable accounted for — and you'll still be stuck, because one dependency that isn't Swift 6-ready can hold your entire module hostage. Mine was a code editor. I'd been using a popular SwiftUI editor package for the DQL query editor, and it transitively pulled in a syntax-highlighting library. Both were lovely. Both were also written for a more innocent time, and neither was going to compile under Swift 6 strict concurrency without upstream changes that weren't happening on my timeline. I had the usual three options, and I want to be honest about how tempting the cowardly ones were: Pin the dependency and leave the whole app at Swift 5. Free today, expensive

1.4 billion iPhones. That's how many devices Apple will push Siri 2.0 to this fall—built on a custom 1.2-trillion-parameter Gemini model and an Extensions system that lets users route Siri's AI brain to Claude, ChatGPT, or Google's own Gemini directly. Tim Cook announced all of it at WWDC 2026 on June 8, his final WWDC keynote before handing the CEO role to hardware chief John Ternus in September. The story isn't just a better Siri. Apple is opening iOS as an AI distribution channel—the largest in history—and the developer implications are immediate. The Gemini Deal Apple licensed a custom 1.2-trillion-parameter Gemini model from Google at a reported $1 billion per year. That's eight times the parameter count of Apple's current 150-billion-parameter on-device foundation model. Bloomberg first reported the deal in March 2026; WWDC confirmed it on stage. The private vs. cloud distinction matters here. Apple isn't routing your queries to Google's servers. The custom Gemini model runs on Apple's Private Cloud Compute (PCC) infrastructure—Apple-owned silicon, Apple-controlled software, with cryptographic attestation that prevents even Apple engineers from reading query contents. This is the same architecture Apple built for existing cloud AI features, now scaled up for a model eight times larger. What that means in practice: Siri can answer complex multi-step questions, reason over your personal context (calendar, messages, mail), and execute cross-app actions. None of it touches Google's data centers. The New Siri App Siri in iOS 27 ships as a standalone app. iMessage-style interface, persistent conversation threads, full chat history synced via iCloud. Two modes: quick invocation through the Dynamic Island (a glowing "Search or Ask" prompt) for fast queries, and the full chat app for extended conversations. Chat-mode Siri is a first-party ChatGPT competitor. Persistent threads, file attachments, on-screen awareness. Ask "what does this error mean?" while looking at an

Indie Hacking the App Store: Navigating Apple's Guidelines for Niche Catholic AI Applications The era of building generic software-as-a-service (SaaS) platforms is shifting. For independent developers and indie hackers, the real opportunity now lies in underserved, highly specific markets. One of the most fascinating and complex niches emerging today is the intersection of artificial intelligence and religious utility. Building a catholic ai application presents a unique set of technical, ethical, and regulatory hurdles. Developers must create highly accurate systems while navigating strict platform guidelines. Unlike general-purpose chatbots, religious applications require absolute precision. A single theological error can ruin user trust. Furthermore, platforms like the Apple App Store have strict rules regarding user safety, privacy, and functionality. This article explores the technical architecture, prompt engineering strategies, and platform compliance steps required to build and launch a successful catholic ai app . Whether you are using Flutter, Swift, or Kotlin, these insights will help you build a robust, secure, and helpful application. Designing a Catholic AI: Aligning with the Catholic Church Stance on AI Before writing a single line of code, developers must understand the domain. Building tools for this community requires respect for established doctrines and traditions. Fortunately, the Vatican has provided clear guidance on this technology. The Catholic Church Stance on AI The Vatican has taken a proactive and surprisingly technical approach to modern computing. Under the leadership of Pope Francis, the Church has introduced the concept of "algorethics"—the ethical development and deployment of algorithms. The catholic church stance on ai emphasizes that technology must always serve human dignity, protect personal privacy, and promote truth. For developers, this means your application must prioritize: Truthfulness: Minimizing errors in theological ou

I used to think the best AI food logging flow would be simple: Take a photo, let the model identify the meal, confirm it, done. That works surprisingly well for a lot of meals. But while building MetricSync, I learned the awkward product truth: the best input method changes depending on what is in front of the user. A photo is great for a plate. A barcode is better for packaged food. Text is better when the user already knows what they ate or wants to fix one detail quickly. The mistake is treating one input mode like the whole product. Photos feel magical until the meal gets messy Photo logging is the most impressive demo because it removes the blank search box problem. The user does not need to know the exact database name for “rice bowl with chicken and avocado.” They can just show the app what they ate. But meals are messy. A photo might miss the sauce. It might not know if the drink is diet or regular. It might confuse a small serving with a large one. It might identify the food category correctly but still need a portion correction. That does not make photo logging bad. It just means the UX cannot end at “AI guessed something.” The real product is the correction loop. Can the user fix the meal without starting over? Barcode scanning is boring in the best way Barcode scanning is not as exciting as AI, but it is often the right tool. If someone is logging a protein bar, yogurt, cereal, or a packaged drink, asking an image model to infer the nutrition facts is silly. The barcode is more direct. That changed how I thought about the app. AI should not be the star of every interaction. Sometimes AI should get out of the way. The goal is not “use AI everywhere.” The goal is “make logging the thing in front of me take the least effort.” For packaged foods, that means barcode first. For mixed plates, that means photo first. For quick edits, that means text. Text still matters The more AI features you add, the easier it is to forget text input. But text is still the fas

Dumpert is a Dutch video site I've watched for years, but there's never been an Apple TV app, so I built one. DumpertTV is an unofficial, open-source tvOS client. Here's how it's put together and a few things that were more interesting than I expected. Disclaimer up front: this project is not affiliated with Dumpert or DPG Media B.V. It's an independent app that uses the public Dumpert API. The stack Swift 6 with strict concurrency ( complete mode) across every target SwiftUI for all UI, tvOS 18+ XcodeGen so the .xcodeproj is generated from a project.yml and never committed CloudKit , GroupActivities (SharePlay), Vision , AVKit , Swift Testing One actor for the network, one source of truth for the UI The whole networking layer is an actor . That makes per-request state like ETags and retry bookkeeping thread-safe without a single lock: actor DumpertAPIClient { private var etags : [ URL : String ] = [:] func fetch < T : Decodable > ( _ endpoint : APIEndpoint ) async throws -> T { // Exponential backoff on 5xx + network errors; honours 304 Not Modified. try await fetchWithRetry ( endpoint , attempt : 0 ) } } The UI reads from a single @Observable @MainActor repository injected through the SwiftUI environment — no Combine, no view models competing over the same state: @Observable @MainActor final class VideoRepository { private(set) var hotshiz : [ MediaItem ] = [] let apiClient : APIClientProtocol // protocol-backed for testing } ContentView () . environment ( videoRepository ) Views just read repository.hotshiz ; updates flow automatically. With Swift 6's strict concurrency on, the compiler kept me honest about every actor hop. Things that were trickier than expected tvOS focus + a top tab bar. Getting a Netflix-style hero carousel to behave with the focus engine took real care. It also made automating screenshots interesting — scripted remote input doesn't reliably drive the simulator, so I added #if DEBUG launch-argument hooks to jump straight to any tab/category f

A user picks a video from Photos. The app turns that video into a file the server can accept. Then it uploads the file. On the surface, this sounds like a simple upload flow. In practice, iOS makes you answer a much more specific question: How do you reliably turn a video from the user's Photo Library into an uploadable MP4 file? At first, I used AVAssetExportPresetPassthrough . It looked like the right default. It preserves the original media as much as possible, avoids unnecessary re-encoding, and is fast when it works. No quality loss, less CPU usage, less battery cost. But some videos failed during export. The error was usually in the AVFoundationErrorDomain Code=-11838 family. Apple describes this error as operationNotSupportedForAsset : an operation was attempted that is not supported for the asset. At first, I suspected an iCloud download issue, a Photos permission edge case, or something retryable inside PHImageManager . That was not the real problem. The actual problem was more fundamental: I was trying to write an iPhone MOV asset into an MP4 file using a passthrough export. The Original Flow The original code was roughly shaped like this: PHImageManager . default () . requestExportSession ( forVideo : asset , options : options , exportPreset : AVAssetExportPresetPassthrough ) { exportSession , info in exportSession ? . outputURL = outputURL exportSession ? . outputFileType = . mp4 exportSession ? . exportAsynchronously { // upload } } The intention was reasonable: Ask Photos for an export session for the PHAsset . Use AVAssetExportPresetPassthrough to preserve the original quality. Write the result as an .mp4 file for upload. Many videos exported successfully this way. That is what made the bug confusing. Some videos worked. Some did not. The hidden assumption was: Any iPhone video can become an MP4 file through a passthrough export. That assumption is not always true. iPhone Videos Are Usually MOV Files To a user, it is just "a video." Internally, an iPh

Hi everybody. We have created this app around two months and this is third version with fixed bugs. Now it is amazing app that synchronization your tasks throughs iPhone iPad Mac via iCloud with no Sign In! And in pocket you will already have a useful notes. It was a huge code work. Hours and hours. Such a pleasure. What I want to note here for you fellas, we were going from these scheme: What's really happening The self-overwrite loop User edits subtask title ↓ onChange fires → scheduleSave() → debounce 1s ↓ ...debounce fires → DataManager.save() writes todos.json to iCloud ↓ NSMetadataQuery detects file change on disk ↓ ↑ └── todosChanged() ───────┘ ↓ taskManager.loadTodos() ↓ self.todos = loadedTodos ← 💥 replaces entire array mid-edit The core problem is that NSMetadataQuery watches the file at the OS level. It has no concept of who made the change — your own app writing the file looks identical to another device syncing a change over iCloud. So every save you make triggers a reload that cancels whatever the user is currently doing. Why subtask titles are worst affected A TextField bound to $subtask.title is live — it reflects the array value character by character. The moment self.todos = loadedTodos runs, SwiftUI throws away the in-memory array and rebuilds from the freshly decoded JSON. If the save hasn't happened yet (debounce still counting down), the loaded file has the old title, and the field visually snaps back. Progress sliders have the same issue but it's less noticeable because a slider value is a Double — the snap-back is a jump rather than disappearing characters. Why it only shows up on real devices The simulator runs everything on the same Mac so iCloud writes are near-instant and the race window is tiny. On a real device the file system is slower and iCloud sync adds latency, making the timing gap between "user is editing" and "reload fires" much more visible. The three fixes needed Fix 1 — Ignore self-triggered reloads in DataManager Track a isS

Most QR scanner libraries for React Native share the same problems — they're unmaintained, they don't support the New Architecture, or they pull in a full camera SDK for what is a single-feature module. I wanted something lean, production-grade, and built the right way. So I built it. This is react-native-qr-camera-pro — a QR and barcode scanner for React Native built entirely with native code. No JavaScript frame processing. No unnecessary dependencies. Swift on iOS, Kotlin on Android, TurboModules and Fabric throughout. Why Native-Only? The common alternative is running frame analysis in JavaScript — grabbing frames via a JS-accessible camera API and running a WASM or JS barcode decoder on them. It works, but it puts real pressure on the JS thread and limits your frame rate. With native-only processing: iOS uses AVCaptureMetadataOutput — Apple's own pipeline for detecting machine-readable codes. Frames are never copied to user space; the kernel hands off a reference to the same buffer. Android uses CameraX ImageAnalysis + ML Kit — Google's on-device barcode scanner backed by hardware-accelerated inference where available. The JS bridge is touched at most once every 500ms to deliver a result. Everything else stays native. Architecture The module is three layers: Architecture The module is three layers, each with a single responsibility: Layer What it does JavaScript / TypeScript Public API — QrCameraProView , startScanning() , stopScanning() , toggleTorch() , useBarcodeScanner() , useCameraError() Native Bridge (TurboModules + Fabric) Type-safe JSI communication between JS and native. Codegen spec drives both the iOS C++ adapter and the Android Kotlin stub. Native Platform (iOS + Android) All camera and barcode logic. AVFoundation on iOS, CameraX + ML Kit on Android.

If you're using Amazon SES and emails to @privaterelay.appleid.com are silently failing, the cause is almost certainly SES's account-level suppression list treating Apple relay DSN errors as hard bounces. Fix: Emails Not Delivered to Apple Private Relay Addresses (Amazon SES) If your app supports Sign in with Apple , some of your users will have a Hide My Email address — a relay address like abc123@privaterelay.appleid.com that forwards to their real inbox. These addresses are easy to break silently. Here's the symptom we ran into and exactly how we fixed it. The Symptom Transactional emails (alerts, welcome emails) worked fine for regular email addresses but never arrived for users who signed in with Apple. We were also receiving bounce notifications like this: Subject : Delivery Status Notification (Failure) An error occurred while trying to deliver the mail to the following recipients: prw8xms8tv@privaterelay.appleid.com Confusingly, some of these emails were being delivered — Apple's relay occasionally returns a DSN error even on successful delivery. But over time, delivery stopped entirely for affected addresses. Root Cause: SES Suppression List Amazon SES has an account-level suppression list . When a send results in a bounce (even a soft or misleading one), SES adds that address to the suppression list and silently drops all future sends to it — no error, no log entry from your code's perspective. Apple's private relay sometimes returns a non-standard response that SES interprets as a hard bounce. Once that happens: Send to Apple relay → Apple returns DSN error → SES logs as hard bounce → Address added to suppression list → Every future send silently dropped We found 9 Apple relay addresses on our suppression list, the oldest suppressed since September 2025 — meaning those users had missed months of emails. The Fix Step 1 — Remove suppressed Apple relay addresses In the AWS Console : Go to Amazon SES (make sure you're in the correct region) Left sidebar → Con
