HTTP load request is not working in iOS12

Question

I having an application which open the direction between two location in a webview using " http://maps.google.com " URL. but it is not working in iOS12. And also enabled the exceptional domain in App transport security plist value. Even though it is not working.

Answer 1

Please update your iOS 12 as the latest version asap.

iOS 12 beta version has an issue of CORS with wkwebview .

Refer to this link.

And it has been fixed now.

Answer 2

For me, the issue was caused by server trust check from the WKWebView.

To fix this I had to handle the challenge authentication callback and return a server trust credential.

Swift 4

func webView(_ webView: WKWebView, 
    didReceive challenge: URLAuthenticationChallenge, 
    completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) 
{
    if(challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust)
    {
        let cred = URLCredential(trust: challenge.protectionSpace.serverTrust!)
        completionHandler(.useCredential, cred)
    }
    else
    {
        completionHandler(.performDefaultHandling, nil)
    }
}
