WKWebView does not load https URL?

Question

I have a WKWebView which should load the following url:

https://buchung.salonmeister.de/place/#offer-details-page?id=907599&venueId=301655

Answer 1

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)
    }
}
