In another tab, reproduce the case for which you are interested. Then switch back to the chrome://inspect tab to view the collected logs. (Log collection will stop if the chrome://inspect page closes or navigates and logs will be lost as they are not persisted.)
This new Inspect tool is intended to “help bridge the gap of missing developer support” that previously required building Chrome for iOS from source. The public version of WKWebView that’s released through the App Store does not support Apple’s Safari Remote Debugging feature.
However, this takes a non-trivial amount of effort which includes setting up a Chromium checkout, installing a current version of Xcode, and waiting for the build to complete. Additionally, a Mac with enough disk space to hold the code and tools is required. This barrier to debugging has led to bugs being filed for specific website failures on Chrome for iOS.
Building Chrome from source is still the “best way to fully debug web pages,” according to Google. Chrome 73 for iOS is available now via the App Store, with the full release notes below:
- If forms aren’t filled in automatically, you can now tap on the icons above the keyboard and easily access your saved passwords, addresses and credit card information.
- Updated default search engines list. You can always choose your own favourite to be the default by performing a search on that website in Chrome, then visit Chrome settings to add the search engine.
