didReceiveAuthenticationChallenge 的 WKWebView iOS 10.3 崩溃？

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，崩溃发生在与信息一致 挑战不是由接收方发送的。

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

感谢任何帮助。这仅在 iOS 10.3 上发生。我猜有些用户有测试版并且正在经历这个。
