Url stop loading inbetween on UIWebView and WKWebView. On iOS 11 only - ios

Question

My URL
https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150
My Findings
The URL works perfectly with all safari and other browsers.
(including iOS 11 mobile safari)
The URL works with all iOS versions other than iOS 11.
I tried to open the URL on both UIWebView and WKWebView but the same issue happens on both. i.e URL stops loading near completion and
nothing happens then.
Here is what I tried so far
import UIKit
import WebKit
class ViewController: UIViewController, WKNavigationDelegate {
// Objects
var webView: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
setupWebView()
loadUrl()
}
func setupWebView() {
let prefs = WKPreferences()
prefs.javaScriptEnabled = true
let config = WKWebViewConfiguration()
config.preferences = prefs
webView = WKWebView(frame: view.frame, configuration: config)
webView.navigationDelegate = self
view.addSubview(webView)
}
func loadUrl() {
webView.navigationDelegate = self
let url = URL(string: "https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150")!
var request = URLRequest(url: url)
request.cachePolicy = .reloadRevalidatingCacheData
webView.load(request)
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
print(webView.url!)
}
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
print(webView.url!)
}
func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
print("error - \(error)")
}
}
I appreciate your help.

WkWebview is recently introduced and UIWebView is officially deprecated now.
Here is link on same issue posted on Apple forum.And Apple staff is currently figuring out the crash.

I have analyse your code that is good and you have need check image formate.When I am using bellow code with image url link working fine .
import UIKit
import WebKit
class ViewController: UIViewController ,WKNavigationDelegate {
var webView: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
setupWebView()
loadUrl()
}
func setupWebView() {
let prefs = WKPreferences()
prefs.javaScriptEnabled = true
let config = WKWebViewConfiguration()
config.preferences = prefs
webView = WKWebView(frame: view.frame, configuration: config)
webView.navigationDelegate = self
view.addSubview(webView)
}
func loadUrl() {
webView.navigationDelegate = self
// let url = URL(string: "https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150")!
let url = URL(string: "https://upload.wikimedia.org/wikipedia/commons/2/2d/Snake_River_%285mb%29.jpg")!
var request = URLRequest(url: url)
request.cachePolicy = .reloadRevalidatingCacheData
webView.load(request)
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
print(webView.url!)
}
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
print(webView.url!)
}
func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
print("error - \(error)")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

// Add plist file
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSExceptionDomains</key>
<dict>
<key>google.com</key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
</dict>
if WKWebView don't not support then declare .m file below code:
#import <WebKit/WebKit.h>
#interface WebScannerViewController()
{
WKWebView *webView;
}
#end
#implementation WebScannerViewController
- (void)viewDidLoad
{
[super viewDidLoad];
webView.hidden=YES;
webView.UIDelegate = self;
webView.navigationDelegate = self;
self.loadingSign.hidden = NO;
webView.frame=CGRectMake(0, 94, Width, Height-128);
webView = [[WKWebView alloc] initWithFrame:self.view.bounds];
webView.customUserAgent = #"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/601.6.17 (KHTML, like Gecko) Version/9.1.1 Safari/601.6.17";
webView.navigationDelegate = self;
NSURL *url = [NSURL URLWithString:#"https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150"];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[webView loadRequest:urlRequest];
}
