>Important message for Windows users!
>Currently the adapter doesn't work for IOS 12+. For IOS 11 there are a few additional steps, as described here.

Getting Started

$3

Before you use this adapter you need to make sure you have the latest version of iTunes installed, as we need a few libraries provided by iTunes to talk to the iOS devices.

#### Linux

Follow the instructions to install ios-webkit-debug-proxy and libimobiledevice

#### Windows

>See the above warning for Windows users

Install ios-webkit-debug-proxy and libimobiledevice. On Windows you can use scoop:

``
scoop bucket add extras
scoop install ios-webkit-debug-proxy
`

#### OSX/Mac
Make sure you have Homebrew installed, and run the following command to install ios-webkit-debug-proxy and libimobiledevice

`
brew update
brew unlink libimobiledevice ios-webkit-debug-proxy usbmuxd
brew uninstall --force libimobiledevice ios-webkit-debug-proxy usbmuxd
brew install --HEAD usbmuxd
brew install --HEAD libimobiledevice
brew install --HEAD ios-webkit-debug-proxy
`

$3

`
npm install remotedebug-ios-webkit-adapter -g
`

$3

In order for your iOS targets to show up, you need to enable remote debugging.

Open iOS Settings => Safari preferences => enable "Web Inspector"

$3

On MacOS you can use Safari to inspect an iOS Safari tab. This will ensure the device is trusted.

On Windows starting iTunes could prompt the "Trust this computer" dialog.

$3

`
remotedebug_ios_webkit_adapter --port=9000
`

BTW: ios-webkit-debug-proxy will be run automatically for you, no need to start it separately.




$3

Open your favorite tool such as Chrome DevTools or Visual Studio Code and configure the tool to connect to the protocol adapter.

Configuration

`
Usage: remotedebug_ios_webkit_adapter --port [num]

Options:
-p, --port the adapter listerning post [default: 9000]
--version prints current version

`

Usage

$3

You can have your iOS targets show up in Chrome's chrome://inspect page by leveraging the new network discoverbility feature where you simple add the IP of computer running the adapter ala localhost:9000.

$3

You can have your iOS targets show up in Mozila debugger.html, by starting remotedebug_ios_webkit_adapter --port=9222 and selecting the Chrome tab.

$3

Install VS Code, and the VS Code Chrome Debugger, then create a launch.json configuration where port is set to 9000, like below:

`json
{
"version": "0.2.0",
"configurations": [
{
"name": "iOS Web",
"type": "chrome",
"request": "attach",
"port": 9000,
"url": "http://localhost:8080/*",
"webRoot": "${workspaceRoot}/src"
}
]
}
`

Architecture

The protocol adapter is implemented in TypeScript as Node-based CLI tool which starts an instance of ios-webkit-debug-proxy, detects the connected iOS devices, and then starts up an instance of the correct protocol adapter depending on the iOS version.
