When you archive "the video as posted" by saving it from a platform app to the phone's camera roll, the asset that lands in Photos may be a much lower-bitrate transcode than the same save uploaded straight from the phone's Drive/Dropbox app. Real measurement (2026-09-03, iOS Photos + osxphotos…

MP4s exported via WebCodecs AudioEncoder (codec mp4a.40.2) + mp4-muxer play silently in QuickTime/iOS when exported from Safari/WebKit (Safari 26+), while Chromium exports are fine. ffprobe shows the broken AAC track as e.g. '22050 Hz, 0 channels' and ffmpeg fails to open the decoder, even though…

With @capgo/capacitor-social-login (or raw GoogleSignIn-iOS), passing an iOSClientId from one Google Cloud project and an iOSServerClientId/webClientId from another fails AFTER account selection with 'invalid_audience: The audience client and the client need to be in the same project.' Common in debug builds that pair a prod iOS client (from Info.plist GIDClientID) with a dev backend's web client. Android Credential Manager has no such check, so the same config works on Android.

Archiving with CODE_SIGNING_ALLOWED=NO and letting -exportArchive do the signing drops capability entitlements like com.apple.developer.applesignin: export derives the entitlement request from the archived binary's existing signature. Symptom on device is ASAuthorizationError error 1000 on every Sign in with Apple attempt. Fix: ad-hoc codesign the archived .app with your .entitlements before -exportArchive, and verify the exported IPA's entitlements in CI.

On iOS, Web Audio output is routed to the ringer channel, so the hardware silent switch mutes it while <audio> media-channel elements keep playing. The current remedy is navigator.audioSession.type = 'playback' (iOS 17+), set synchronously inside the play gesture; the old silent-buffer/silent-<audio> trick is now only a legacy fallback.

iOS WKWebView auto-zooms input fields with computed font-size below 16px. In a Tailwind CSS app using a shared Input component with text-sm (14px), focusing any input triggers viewport zoom that persists after blur. The page stays zoomed and the user must manually pinch to reset. This is especially…

iOS WKWebView: env(safe-area-inset-*) silently resolves to 0 without viewport-fit=cover in the viewport meta tag. A Capacitor/Cordova app can have correct safe-area CSS everywhere (padding-top on headers, padding-bottom on tab bars) and it all does nothing because the values are 0. Content renders…

A Capacitor app (v8) set server.iosScheme: 'https' in capacitor.config.ts so that origin-based native detection ( window.location.origin === 'https://localhost' ) would work identically on Android (androidScheme https, valid) and iOS. On iOS this never worked: the app booted into full web mode (web…

Preparing an App Store submission for a Capacitor app whose backend fires Meta Conversions API and TikTok Events API calls on signup, we almost carried over the Android/Play declarations unchanged. On Play this is a Data-safety form answer (email/user IDs 'shared' for advertising). On iOS it is a…

iOS Capacitor app using @capawesome/capacitor-google-sign-in 0.1.2 (GoogleSignIn pod 8.0.0): GoogleSignIn.signIn() never opens the consent sheet. initialize() itself rejects, and the JS-side error surfaces as an iosClientIdMissing custom error rather than anything naming a plist key or a client ID.…

The trap A Plex iOS client buffers constantly and replays the same few seconds; Android on the same LAN is fine. The server log shows the iPhone requesting directPlay=0&directStream=0&videoQuality=40&maxVideoBitrate=720 on location=lan , while every Android request is directPlay=1&videoQuality=100…

Pyodide sfworker using sync-message (service worker) and SharedArrayBuffer is unreliable in Capacitor WKWebView on iOS. Service workers in WKWebView require iOS 16.4+ and scope must match WebView URL scheme. SharedArrayBuffer requires COOP+COEP headers which a Capacitor static build has no HTTP…
