How to load local directory inside iframe in iOS Swift?

问题

In loadHTMLStringImage function i have been loaded index.html

let htmlPath = Bundle.main.path(forResource: "index", ofType: "html")
let htmlUrl = URL(fileURLWithPath: htmlPath!, isDirectory: false)   
self.webView.loadFileURL(htmlUrl, allowingReadAccessTo: htmlUrl)

After loading I have been checking md5 string. From the md5 zip file, I am unzipping to the local directory and got the local file directory URL. And passing the local directory URL to iframe src. But it shows an empty screen.

In console it shows:

Received an unexpected URL from the web process: 'file:///var/mobile/Containers/Data/Application/CECB33DC-8DE8-4FB0-BD28-73D46B47CB7C/Documents/appday/gng/v0-8/build/index.html'
2020-02-11 16:55:53.659227+0530 appday[15903:3679464] [Process] 0x10791c018 - WebPageProxy::Ignoring request to load this main resource because it is outside the sandbox

In viewDidLoad I have WKPreference too:

webView.navigationDelegate = self
webView.uiDelegate = self
webView.allowsBackForwardNavigationGestures = true

webView.configuration.preferences.javaScriptEnabled = true
webView.configuration.preferences.setValue(true, forKey: "allowFileAccessFromFileURLs")

Here, I am loading the local directory URL to iframe src. And df is the unzipped file local directory URL path:

My URL path looks like this:

'file:///var/mobile/Containers/Data/Application/CECB33DC-8DE8-4FB0-BD28-73D46B47CB7C/Documents/appday/gng/v0-8/build/index.html'


let url_path = df.absoluteString
let setPath = url_path

let js = "setFrame('" + setPath) 
print("js::\(js)")

Here I am trying to load local file directory URL to iframe src.

Here is my local index.html file javascript where i am loading iframe src:

 <iframe id='formFrame' src="" width="100%" height="100%" frameborder="0" scrolling="yes" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe>

    function setFrame(url) {
  document.getElementById('formFrame').src = url;

}

[Note: I am iframe content from a local directory URL not loading in local HTML file]

Any help much appreciated pls...

import UIKit
import WebKit

class EventWallVC: UIViewController {

let directoryName : String = "appday/gng/v0-8/build"
//MARK: - IBOutlet
@IBOutlet weak var webView: WKWebView!
@IBOutlet weak var lblEventWall: UILabel!

override func viewDidLoad() {
       super.viewDidLoad()
       SVProgressHUD.show()
       self.webView.navigationDelegate = self

        var indexfileurl = URL(string: "")
        let path = (NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString).appendingPathComponent("\(directoryName)/\(index.html)")
         indexfileurl = URL(fileURLWithPath: path)

       //let url = Bundle.main.url(forResource: "index", withExtension: "html", subdirectory: "")! /* your local bundle in save index.html file to get this */
       self.webView.loadFileURL(indexfileurl, allowingReadAccessTo: indexfileurl)
       let request = URLRequest(url: indexfileurl)
       self.webView.load(request)

   }
}

extension EventWallVC: WKNavigationDelegate {
   func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
       SVProgressHUD.dismiss()

   }
}
