I haven t tried it  but iOS WebKit debug proxy  ios webkit debug proxy   iwdp  supposedly lets you remotely debug UIWebView  From the README md     The ios webkit debug proxy  aka iwdp  allows developers to inspect   MobileSafari and UIWebViews on real and simulated iOS devices via   the Chrome DevTools UI and Chrome Remote Debugging Protocol  DevTools   requests are translated into Apple s Remote Web Inspector service   calls

iOS WebKit debug proxy is the simpliest solution - debug and live preview directly in Chrome

Note  I have no affiliation with Ghostlab creators Vanamco whatsoever   It was important to me to be able to debug Chrome-specific problems  so I set out to find something that could help me with that  I ended up happily throwing my money at Ghostlab 3  I can test Chrome and Safari mobile browsers as if I was viewing them on my desktop  It just gives me a LAN address to use for any device I   d like to debug  Each application using that address will appear in the list in Ghostlab       Highly recommended

There is an open bug on Chromium  https   bugs chromium org p chromium issues detail id 584905  Unfortunately they depend on Apple to open up an API in WKView for this to happen  after which maybe debugging will be available from Safari

Vorlon JS can be used for remote debugging of iOS or any other client    Just install it globally using npm i -g vorlon Start server using vorlon With the server is running  open http   localhost 1337 in your browser to see the Vorlon JS dashboard The last step is to enable Vorlon JS by adding this script tag to your app   lt script src  http    lt yourExternalIP gt  1337 vorlon js  gt  lt  script gt  All connected clients e g  iPhone  Android will become available in client list on Vorlon JS dashboard    Note that this approach can also be used to debug apps not running on localhost using ngrok  See https   stackoverflow com a 45443203 2073920 for details   Disclaimer  I am just a user and I am not affiliated with Vorlon JS and ngrok

From my understanding  Google Chrome utilizes the iOS s UIWebView rather than a full blown implementation of Chrome like the Android counterpart

User · Answer

You cannot directly remote debug Chrome on iOS currently  It uses a uiWebView that may act subtly different than Mobile Safari   You have a few options   Option 1  Remote-debug Mobile Safari using Safari s inspector  If your issue reproduces in Mobile Safari  this is definitely the best way to go  In fact  going through the iOS simulator is even easier   Option 2  Use Weinre for a slimmed down debugging experience   Weinre doesn t have much features but sometimes it s good enough   Option 3  Remote debug a proper uiWebView that functions the same   Here s the best way to do this  You ll need to install XCode    Go to github com paulirish iOS-WebView-App and  Download Zip  or clone   Open XCode  open existing project  and choose the project you just downloaded  Open WebViewAppDelegate m and change the urlString to be the URL you want to test  Run the app in the iOS Simulator  Open Safari  Open the Develop Menu  Choose iOS Simulator and select your webview  Safari Inspector will now be inspecting your uiWebView

The selected answer is only for Safari  At the moment it s not possible to do real remote debugging in Chrome on iOS  but as with most mobile browsers you can use WeInRe for some simple debugging  It s a bit work to set up  but lets you inspect the DOM  see styling  change DOM and play with the console     To setup    Install nodejs npm install -g weinre weinre --boundHost -all- Open http    wifi-ip-address  8080  and copy the target script code Paste the script tag into your page  or use the bookmarklet  Click on the link to the debug client user interface  http    wifi-ip-address  8080 client  anonymous  When you get a green line under Clients the browser is connected   The bookmarklet is a bit more of an hassle to install  It s easiest if you have bookmark-sync turned on for both desktop and mobile Chrome  Copy the bookmarklet url from the local weinre server  same as above   Unfortunately it doesn t work because it s not url-encoded properly  So open the JavaScript console and type in   copy encodeURI          paste bookmarklet inside quotes   You should now have the url-encoded bookmarklet in your clipboard  Paste it into a new bookmark under Mobile Bookmarks  Call it weinre or something simple to type  It should be synced to your mobile pretty fast  so load the page you want to inspect  Then type in the bookmark name in the url-bar  and you should see the bookmarklet as an auto-complete-suggestion  Click it to run bookmarklet code

Even I am looking for the same feature  and as of today  its yet to be implemented  I can think of two options however     I noticed that the behavior of Chrome and Safari are quite identical  Chrome even supports the Gyroscope and other related events which are supported by Safari  I am currently debugging my Web App by enabling the debug console on Safari  Through Settings- Safari  Also try Adobe Shadow  which allows remote debugging inspection and Sync    HTH

I am using remotedebug-ios-webkit-adapter  works well for me with IOS and debugger open in Chrome on Windows 10   Will be glad if it helps some one Link

Many remote consoles work fine  http   farjs com is my project  and I was able to successfully debug issues specific to Crome iOS and not happening in safari using it   and probably all other mobile browsers   The problem is that injecting the debugging code is slightly tricky since Chrome doesn t allow you to install bookmarklets    Instead you could open one tab on the page that you would debug  and another on farjs com and then click  the bookmarklet   Copy the bookmarklet JS code  get back to the first tab  with the page that should be debugged  and paste the bookmarklet code in the location bar   Last step is to scroll to the beginning of the location bar and add  javascript    since Chrome will remove it
