如何在swift中检查消息正文类型

Question

我想知道swift中的消息正文类型
因为我有Objc的[message.body class]这样的代码
如何使用swift

- (void)userContentController:(WKUserContentController*)userContentController didReceiveScriptMessage:(WKScriptMessage*)message {
NSString *name = message.name;
NSLog(@"message name = %@",name);
NSLog(@"body class = %@",[message.body class]);
}

Answer 1

guard let someString = message.body as? String else { return }
print(someString)
