WKWebView에서는 변화사항이 있는거같다.

결론

WKNavigationDelete추가

    override func viewDidLoad() {

        super.viewDidLoad()

        WebView.navigationDelegate = self

}

HTML페이지에는

location.href = "custom-scheme//test"

    func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {

        if let url = navigationAction.request.url, url.scheme != "http" && url.scheme != "https" {

            print(url.scheme)

            print(url.host)

            //UIApplication.shared.openURL(url)

            decisionHandler(.cancel)

        } else {

            decisionHandler(.allow)

        }

    }

PRINT결과

Optional("custom-scheme")

Optional("test")
