How to Debug Websites on iPhone Safari

Since the iPhone launched in 2007, a mobile version of Safari has been included in all iOS devices. If a user doesn’t change it, it’s the default browser on Apple devices. Last year, Apple’s number of active devices witnessed a significant increase to 1.5 billion. Since the user base keeps rising, Apple constantly ensures a near-perfect user experience and an optimized performance across all its devices. Devs or testers can locate it in the development view and use the element selector to inspect specific Safari mobile web elements after activating the inspector. IPhone holds a significant share of Apple’s revenue and has been one of its pioneer products.

  • The Safari debugger is accessible from the Sources tab of the Developer Tools window, or by entering the debugger

  • I have heard of people running over to Best Buy or an Apple Store to quick debug something on a display machine.
  • Learn how to build a Safari Web Extension that works for all devices, and discover how you can convert an existing extension to Safari through Xcode and the Safari Web Extension Converter.
  • This suite of command-line tools includes an installer package, tutorial, user documentation, and reference.
  • In my recent efforts in troubleshooting one small “nuance” between Chrome on Mac and Chrome and Safari on iOS (yes, all three were acting differently), I needed to debug my browser on my iPad and/or iPhone.

Dummies has always stood for taking on complex concepts and making them easy to understand. Dummies helps everyone be more knowledgeable and confident in applying what they know. After the Debug Console is enabled, Safari reports any errors it encounters when accessing a website. At the top of every web page, just under the address bar, the Debug Console reports any HTML, JavaScript, or CSS errors. Write automated tests to exercise web content in Safari to ensure a good user experience, and run those same tests against other browsers with a WebDriver-compliant driver.
