如何在Swift中解析带有#的URL？

let urlString = "https://example.com/path?key=value#fragment"
if let url = URL(string: urlString) {
    if let components = URLComponents(url: url, resolvingAgainstBaseURL: false) {
        // 访问URL的各个组成部分
        let scheme = components.scheme
        let host = components.host
        let path = components.path
        let query = components.query
        let fragment = components.fragment
        
        // 打印结果
        print("Scheme: \(scheme ?? "")")
        print("Host: \(host ?? "")")
        print("Path: \(path)")
        print("Query: \(query ?? "")")
        print("Fragment: \(fragment ?? "")")
    }
}

Scheme: https
Host: example.com
Path: /path
Query: key=value
Fragment: fragment
