Apple requires all software applications in the App Store to use the WebKit engine, even the current version of Google Chrome. This is mandatory according to the company's terms and conditions. However, it seems that the Chromium developers are laying the groundwork for a future in which Blink, the same engine that powers the browser, will be used for more than just browsing the web.
Chrome Blink is an open-source engine designed specifically for the Chrome browser. It is based on WebKit, which was previously used to power Safari, but has been heavily modified by Google to provide improved performance when loading websites and web applications.

A bug report on the issue says that this “innovative implementation will allow us to evaluate graphics and input lag through the process of generating logs for analysis.”

The post also emphasizes that the experiment is just an exploration, not something that will ship in the final product. It is currently unknown why Google chose to launch a project using Blink for iOS, given that Apple strictly adheres to its WebKit policy.
Recently, the US government argued that Apple should open up platform , while other EU regulatory terms have indicated that users should be able to obtain apps outside of their native store environment – leading some to believe that Apple will soon have no choice but to allow practices it previously resisted.

If the rumors are true, then Chrome could have its own app powered by Blink, which would bring it in line with Google's other services . This could give Chrome a competitive advantage over its rivals, who may opt for different default engines instead of Apple's WebKit engine.
