Now, Google has switched to WKWebView, which Apple introduced with iOS 8. It’s been a while since iOS 8 was state of the art, but Google notes that migrating to WKWebView “brought significant challenges.” Specifically, Google notes that the new framework didn’t feature an obvious way to manage cookies and form and SSL handling was also problematic. iOS 9 fixed some of these issues and now the team is ready to make the switch official.
Thanks to moving to the new framework, the browser isn’t just faster, but also more stable — and even when a page crashes, the app itself now doesn’t crash anymore. Instead, it will simply display an error page, just like on the desktop.
