Google has announced that the code for Chrome for iOS is being added to its Chromium project. This means like any other Google platform
Google has noted that Chrome iOS was kept separate from the rest of the Chromium project due to the additional complexity required for the platform. Due to constraints of the iOS platform, all browsers must be built on top of the WebKit rendering engine. Google said Chrome on iOS had to support WebKit’s rendering engine as well as Blink, a engine supported by Chrome for other platforms. The development speed will be faster for tests of Chrome on iOS, added the company.
Google wrote in a blog post,
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
