Original info from this SO question.

Works in Objective-C or Swift.

In Swift, you'll need to add the following line to your bridging header:

#import "WKPreferences+DevExtras.h"

Usage looks like

let webView = WKWebView(frame: window.frame)
webView.configuration.preferences.enableDevExtras();

Bad idea to do it this way: you may get rejected due to use of internal APIs. Use the setValue way instead.

This solution doesn't seem to work in iOS. It just works in OS X. Am I right?

is it Working fine or getting any issues ?
