I am trying to develop websites and test for backwards compatibility with older versions of things. I have an iPad Mini with iOS 9.x.x and am trying to simply load a page in Safari and see why the Javascript is not doing what it should be doing. The Web Inspector, on my Mac Safari, is completely useless.
I can see the iPad in the Developer menu. I can tell it to load the page that's on the iPad. But it won't provide any useful information. No console logging, nothing. All I see is a warning that apparently puts a halt to everything: Audit Warning: 'data-custom' is too new to run on this inspected page.
Apple has this bizarre habit of breaking things and making it impossible for us to even use older hardware. I can not find a mainstream browser, such as Chrome or Firefox, that will install on this iPad. I will not spend the money for a new iPad because, predictably, it will be useless in another year or two due to incompatibility with the newest OS and everything else that requires the latest OS just to install.
I'm accustomed to software running on newer operating systems for at least a decade. I'm accustomed to easy debugging information, even as simple as the Javascript Console working. It's amazing how hard Apple makes it for us to provide our software customers with useful products. Can't even test on an iPad with iOS 9? Ridiculous.

Sometimes you run into an issue where a web page won’t display correctly on iOS. Since mobile devices don’t have robust debugging tools, you can’t easily troubleshoot issues on the devices. The solution is to use Safari’s Web Inspector and today I’m going to walk you through how to set this up and debug an actual (contrived) JavaScript issue with Safari on Mac OS X.
In order to deploy and debug wirelessly on your device, you must pair your iOS device or Apple TV with Xcode on your Mac. Once paired, you can select it from the device target list in Visual Studio. Macos delete app command line. The following pairing process should only need to happen once per. Teams can also leverage the Local testing feature similar to the one in the desktop browser versions to debug websites in development on real mobile devices. Try Safari Remote Debugging on Real Devices. That’s how teams can remotely debug and optimize their sites for Safari (Mac and iOS) without any complicated setup.
