Here you can find more information about Appium automation tool.
Execute your iOS test using Appium (by default it is expected to listen on http://localhost:4723) and set a breakpoint where you want to investigate the UI tree. Open/refresh iOS Inspector.html web page in your favourite web browser, wait for a while until the data is loaded and you are ready to go. The inspector currently supports showing of element attributes, element location by XPath, dynamic setting of retina scale factor and, naturally, two-way visual elements location using a screenshot and the UI tree.
Note: The Accessibility Id property can be presented as @name attribute in XPath expessions.
Change the default Appium server address if needed inside inspector.js file, APPIUM_ROOT constant.
