I didn\'t find a lot of instruction setting up crosswalk for iOS it seems like it should be as simple as:
cordova plugin add cordova-plugin-crosswalk-webview
Crosswalk will soon provide a cordova plugin for Crosswalk ios, see ticket https://crosswalk-project.org/jira/browse/XWALK-4911
As JesseMonroy so helpfully answered(feel free to upvote him) the cordova crosswalk plugin is only for android.
Because of apple's terms of service, crosswalk for iOS uses wkwebview instead of what non-ios version of chrome would use.
Since there is no cordova plugin I know of for crosswalk iOS, I found plugins for WKWebView
The plugin I used was: https://github.com/Telerik-Verified-Plugins/WKWebView
This is probably a better option: https://github.com/apache/cordova-plugin-wkwebview-engine.. But it errored for me.
As stated by Honry:
Crosswalk will soon provide a cordova plugin for Crosswalk ios, see ticket https://crosswalk-project.org/jira/browse/XWALK-4911
XWalk will not be supporting an iOS plugin afterall because it does not provide any must have advantages over wkwebview
A review of the plugin repository does NOT indicate a cordova-plugin-crosswalk-webview that supports iOS. This means crosswalk does not work as a plugin for iOS.
Yes there is support for Crosswalk for iOS, but you must install via the github repository or other means.
FWIW: there is a WkWebview plugin
