WKWebView iOS 10.3 crash for didReceiveAuthenticationChallen

Question

func webView(webView: WKWebView, didReceiveAuthenticationChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Void) {
    var user: String?
    var password: String?
    switch providerID {
    case "197": // ABC Stagging
        user = "ABC"
        password = "abc"
    default:
        break
    }
    if let user = user, password = password {
        let credential = NSURLCredential(user: user, password: password, persistence: NSURLCredentialPersistence.ForSession)
        challenge.sender?.useCredential(credential, forAuthenticationChallenge: challenge)
        completionHandler(NSURLSessionAuthChallengeDisposition.UseCredential, credential)
    }
}

根据crashlytics崩溃，正在与信息一致。

    challenge.sender?.useCredential(credential, forAuthenticationChallenge: challenge)

任何帮助将不胜感激。这仅在iOS 10.3上发生。我猜有些用户有Beta，并且正在经历。
