Update WKWebView Cookie Values

Question

My Requirement is to update the cookies that are set to WKWebView. I'm able to update the cookies in NSHTTPCookieStorage, but the same cookies are not reflected to WKWebView cookies(The update values are present in NSHTTPCookieStorage but are not set to WKWebView)

The following is code that i have used to set that cookies to AJAX calls.

NSString *strURL = DASHBOARDURL;

NSURL *url = [NSURL URLWithString:strURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

[request setURL:url];

NSMutableString *script = [[NSMutableString alloc] init];
NSMutableString *cookieString = [[NSMutableString alloc] init];

for (NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {
    [cookieString appendString:[NSString stringWithFormat:@"%@;", cookie.getCookieString]];
    [script appendString:[NSString stringWithFormat:@"document.cookie='%@';",cookie.getCookieString]];

}
[request setValue:cookieString forHTTPHeaderField:@"Cookie"];
//cookies for further AJAX calls
WKUserContentController *userContentController = [[WKUserContentController alloc] init];
WKUserScript *cookieInScript = [[WKUserScript alloc] initWithSource:script
                                                      injectionTime:WKUserScriptInjectionTimeAtDocumentStart
                                                   forMainFrameOnly:NO];
[userContentController removeAllUserScripts];

[userContentController addUserScript:cookieInScript];

WKWebViewConfiguration *webViewConfig = [[WKWebViewConfiguration alloc] init];

webViewConfig.userContentController = userContentController;

CGRect viewRect = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height);
wkWebView = [[WKWebView alloc] initWithFrame:viewRect configuration:webViewConfig];
wkWebView.navigationDelegate = self;
[wkWebView loadRequest:request];
[self.view addSubview:wkWebView];

After updating the cookies, I tried to print the existing cookies in my NSHTTPCookieStorage, which shows the updated values.

NSLog(@"cookies:%@",[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]);

I also tried printing the script in WKNavigationDelegate after updating the cookies, but it shows old values.

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{
NSLog(@"Script: %@",[wkWebView.configuration.userContentController.userScripts firstObject].source);

}

The following code fixed my issue:

NSMutableString *script = [[NSMutableString alloc] init];
for (NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {
    [script appendString:[NSString stringWithFormat:@"document.cookie='%@';",cookie.getCookieString]];
}
[wkwebView evaluateJavaScript:script completionHandler:^(id test, NSError *error){
    NSLog(@"test");
}];


-(NSString *)getCookieString 
 {
 NSString *string = [NSString stringWithFormat:@"%@=%@;expiresDate=%@;path=%@;sessionOnly=%@;isSecure=%@",
        self.name,
        self.value,
        self.expiresDate,
        self.path ?: @"/",
        self.isSecure ? @"TRUE":@"FALSE",
        self.sessionOnly ? @"TRUE":@"FALSE"];
 return string;
}
