So I have this function on my site:

function appQrHandlerSet(result) {
    jQuery(function() {
        jQuery('#readed_qr_url').val(result.url);
        jQuery(this).getLayerForm('#qr_handler_layer');
            });      
}

So I have this function on my site:

function appQrHandlerSet(result) {
    jQuery(function() {
        jQuery('#readed_qr_url').val(result.url);
        jQuery(this).getLayerForm('#qr_handler_layer');
            });      
}

From the iOS app, I have to call this function and pass a JSON to it, how can I achieve that? I've been trying to make it work for 3 days now, but I gave up because something is not working right.

Thanks in advance!

According to your code, the parameter result should contain the property url. We suppose that the url contains the JSON data you want to pass.
Try the following 2 approaches:

// Approach 1:
func callJS() {
    let json = "{ url:\"An url with json?\"}"
    let scriptString = "let result=\(json); appQrHandlerSet(result);"
    webView?.evaluateJavaScript(scriptString, pletionHandler: { (object, error) in

    })
}

// Approach 2:
func initWebViewWithJs() {
    let config = WKWebViewConfiguration()
    config.userContentController = WKUserContentController()

    let json = "{ url:\"An url with json?\"}"
    let scriptString = "let result=\(json); appQrHandlerSet(result);"
    let script = WKUserScript(source: scriptString, injectionTime: WKUserScriptInjectionTime.atDocumentEnd, forMainFrameOnly: true)
    config.userContentController.addUserScript(script)

    webView = WKWebView(frame: CGRect(x: 0, y: 0, width: 320, height: 400), configuration: config)
}
