I am injecting a script in UIWebView using Swift. When a certain tap action happens, the script takes care of the handling. While this happens, the JavaScript is supposed to make a call to one of the functions in Swift, which saves the data sent from JavaScript in native variable. Please help me in making this call.

People won't be able to help without showing what you have done so far. Bits of code snippets would do.Jaya Mayu– Jaya Mayu2018-07-31 10:21:26 +00:00Commented Jul 31, 2018 at 10:21

For this you need to make a callback from your JavaScript file, I used one JavaScript editor in that,This was the code :-
window.location = "callback://0/"+ pass your value here
And in your swift file, use the UIWebViewDelegate :-
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
let urlString = request.url?.absoluteString
//NSLog(@"web request");
//NSLog(@"%@", urlString);
if ((urlString?.range(of: "callback://0/")) != nil) {
// We recieved the callback
let value = urlString?.replacingOccurrences(of: "callback://0/", with: "")
}
}
