Chrome for iOS has always been kept separate due to the fact that it relies on the WebKit rendering engine rather than Google’s Blink engine. This is because of Apple’s constraint on browsers on iOS, requiring all of them to run on WebKit.
“For Chromium, this means supporting both WebKit as well as Blink, Chrome‘s rendering engine for other platforms. That created some extra complexities which we wanted to avoid placing in the Chromium code base,” the blog added.
For Chrome users, there won’t be any major changes on the surface. Rather, Google explains that the speed of developing new versions of Chrome for iOS will be accelerated since tests can now be run with the entire Chromium community.[related-posts]
