我的 Swift 代码：

self.webView.evaluateJavaScript("javascript: localStorage.setItem('usr_dtls', 'vivek')") { (result, error) -> Void in
            print(result)
            print(error)
        }

Error message in cosole:
nil
Optional(Error Domain=WKErrorDomain Code=4 "A JavaScript exception occurred" UserInfo={WKJavaScriptExceptionLineNumber=1, WKJavaScriptExceptionMessage=SecurityError (DOM Exception 18): The operation is insecure., WKJavaScriptExceptionColumnNumber=25, WKJavaScriptExceptionSourceURL=about:blank, NSLocalizedDescription=A JavaScript exception occurred})

知道出了什么问题吗？
