Google announced
that Google is now making Chrome Browser an open source for iOS and the code
for Chrome on iOS has been moved into the Chromium open-source repository. Since, there was
some complexity in chromium project, Google’s Chromium project has been a
desktop-only matter, but that changed in 2015 with the addition of the Android version.
Google announced that Google is now making Chrome Browser an open source for iOS and the code for Chrome on iOS has been moved into the Chromium open-source repository.
Due to constraints of the iOS platform, all browsers must be built on top of
the WebKit rendering
engine. 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.
Given Chrome’s
commitment to open-source code, we’ve spent a lot of time over the past several
years making the changes required to upstream the code for Chrome for iOS into
Chromium. Today, that upstreaming is complete, and developers can compile the
iOS version of Chromium like they can for other versions of Chromium. 
Development speed is also faster now that all of the tests for Chrome for iOS
are available to the entire Chromium community and automatically run any time
that code is checked in.

You can download Google Chrome from the App Store for free.
