<pre>Early this year Chrome for iOS migrated from UIWebView to WKWebView. WKWebView gave us a huge improvement in stability, but inability to use custom network protocols made impossible to support the following features:
Privacy
- Block 3rd party cookies
- Do Not Track
- Non-ephemeral Incognito browsing (so users are not logged out if they background the app and the app is killed in the background.)
Security
- HSTS preloads
- Public key pinning
- Safe browsing
- SHA-1 deprecation warning
Other features
- Data Saver
- Downloads if authentication is required (no access to cookies)
- Multiple profiles support
- QUIC network protocol
- WebP image format</pre>
