iOS 8 introduced WKWebView, a modernised web view for iOS with more features, particularly notably JIT compilation for Javascript code which significantly improves performance.
However WKWebView on iOS 8 had some bugs which prevented Cordova using it by default. AFAIK there are plugins that can use it, but they all say "beta", "incomplete" etc. Also as far as I'm aware iOS 9 fixes the bugs that stopped Cordova defaulting to WKWebView in iOS 8.
So what is the state of WKWebView in Cordova on iOS 9? I can't seem to find any information about this. Does Cordova default to WKWebView on iOS 9? If not why not, and can it be officially enabled another way?

Apple has not removed UIWebView
in iOS 13 beta, so looks like it can be used at least for another year.
Ionic WebView plugin, starting in version 3.0.0 no longer uses a web server, but the WKURLSchemeHandler
instead, that required to drop support for iOS 10 and older.
Still backport most fixes to 2.x branch that still have the web server for those that want to support iOS 10.
WKWebView was not integrated into cordova-ios 5.0.0, a plugin is still required to use it. Should be there for 6.0.0 version.
And now there is Ionic Capacitor available, an Apache Cordova alternative that was built with the WKWebView
since the beginning. It has its own set of plugins, but it's also compatible with most Cordova plugins.

Apple has deprecated UIWebView
in iOS 12 and will probably remove it in iOS 13.
Apache Cordova has announced that it will integrate the cordova-plugin-wkwebview-engine
into cordova-ios
in next major release (5.x.x), but UIWebView
will still work and be the default one. Also, you'll be able to switch between them in runtime to easily test your app.
In a future release it will remove the whole UIWebView
code and the WKWebView
will be the only option.
But cordova-plugin-wkwebview-engine
still have a lot of issues. I still recommend using cordova-plugin-ionic-webview as using GCDWebServer
solves most of the WKWebView
issues.
New edit: November 2017
Ionic team has launched a new WKWebView plugin that is no longer a fork of the Cordova one and uses GCDWebServer
internally and overcomes most of the Cordova plugin known issues.
New edit: 24 August 2016
Updated just to add a fork of the apache's WKWebView
plugin created by the ionic framework team that adds some enhancements to the plugin.
https://github.com/driftyco/cordova-plugin-wkwebview-engine
The enhancements will probably land on the core plugin soon, but you can take a look and test the ionic fork now.

cordova ios 4.0.0 has been released
and the version 1.0.0 of cordova-plugin-wkwebview-engine
To try it:
cordova create wkwvtest my.project.id wkwvtest
cd wkwvtest
cordova platform add ios@4
cordova plugin add cordova-plugin-wkwebview-engine
As I already told, cordova-plugin-wkwebview-engine only supports iOS 9, on iOS 8 it will use UIWebView and has some know issues
If you want to support iOS 8 too, you can use the wkwebview-engine-localhost (experimental) or cordova-plugin-wkwebview from Telerik, both of them use a local web server
https://github.com/apache/cordova-plugins/tree/master/wkwebview-engine-localhost
OLD MESSAGE:
You can use WKWebView with cordova using the WKWebView plugins available.
The problem you mention is that WKWebView can't load local files, so the plugins use a local web server to workaround the problem.
There are some of them like this one from telerik https://github.com/Telerik-Verified-Plugins/WKWebView (with the web server built in) or the official from cordova team https://github.com/apache/cordova-plugins/tree/master/wkwebview-engine-localhost (with the web server as dependency plugin)
As the bug you mention is fixed on iOS 9, the current cordova plugin (compatible with iOS 8 and iOS 9, using the web server) has been renamed to wkwebview-engine-localhost, and the current name cordova-plugin-wkwebview-engine will be used for a new plugin that will support iOS 9 only and won't use the web server
You can see the issues to track the progress here

EDIT: I bring news https://shazronatadobe.wordpress.com/2015/09/09/apache-cordova-ios-4-0-0-and-wkwebview-support/
WKWebView support
The cordova-plugin-wkwebview-engine plugin will be iOS 9 only and it will be a core plugin. The development of this updated plugin is still in progress. Apple has fixed the bug where we couldn’t load documents from file:// urls, and it is iOS 9 only. On non-iOS 9 devices, cordova-ios will fallback to using the UIWebView.
The old version of this plugin used a local webserver to load your main document. This older plugin can be used where you want to use WKWebView in both iOS 8 and iOS 9 deployments, but the plugin will remain as a cordova-labs experiment. This plugin has some re-factoring work to be done.
