…on iOS YouTube tightened embed verification in 2025, causing error 152-4 for all WKWebView-based YouTube iframe embeds that set origin to 'https://www.youtube.com'. The WKWebView does not send proper HTTP Referer headers for loadHTMLString content, so YouTube rejects the mismatched origin. Change origin to 'https://www.youtube-nocookie.com/embed/' which is the confirmed fix adopted by Flutter (youtube_player_flutter#1087), React Native (react-native-webview#3889), and iOS WKWebView (YoutubePlayer-in-WKWebView#43) communities.

Summary
originfromhttps://www.youtube.comtohttps://www.youtube-nocookie.com/embed/in the iOS implementation (index.ios.ts)Problem
YouTube tightened their embed verification in 2025. All WKWebView-based YouTube iframe embeds that set
origin: 'https://www.youtube.com'now receive error 152-4 ("This video is unavailable").The root cause is that
WKWebView.loadHTMLString:baseURL:does not send proper HTTPRefererheaders for cross-origin requests (WebKit Bug 169846), so YouTube's iframe API rejects the mismatched origin.This affects all videos — not specific ones.
Fix

https://www.youtube-nocookie.com/embed/as the origin, which is the confirmed workaround adopted across multiple communities:Test plan
