Firstly create an extension on WKWebView that defines a 'runJavaScriptInMainFrame:' method. In the extension method, use NSInvocationOperation

The NSInvocationOperation class is a concrete subclass of NSOperation that you use to initiate an operation that consists of invoking a selector on a specified object. This class implements a non-concurrent operation.

to call the undocumented '_runJavaScriptInMainFrame:' method.

 extension WKWebView {
        func runJavaScriptInMainFrame(#scriptString: NSString) -> Void {
            let selector : Selector = "_runJavaScriptInMainFrame:"
            let invocation = NSInvocationOperation(target: self, selector: selector, object: scriptString)
            NSOperationQueue.mainQueue().addOperation(invocation)
        }
    }

Now call this one:-

webview.runJavacriptInMainFrame:(scriptString: "Write Particular javascript code")
