Similar to remote debugging with iOS(using Safari) or Android(using Chrome), I'd like to do the same thing with Argon.
I assume you mean debugging argon.js apps using Argon4, the current version of the iOS app (at http://argonjs.io).
Like other apps that use Apple's built-in WkWebView, you can't use a remote debugger, since Apple won’t allow the remote debugger to work for any app except mobile safari. Which makes sense, since there are lots of technologies for building mobile apps using web tech, and people don’t want folks poking around inside their apps.
When developing a website using argon.js, if you are doing geospatial AR (essentially, anything that doesn't use Vuforia), you can just run the app in mobile Safari and use the remote debugger as you might hope.
My general approach is to developing and debugging with argon.js on Argon4 is:
FYI you may find http://vorlonjs.com/ is useful for remote debugging an app while running in Argon.
