I am using the Stack Overflow API in Swift but keep getting an error:  

> The data couldn’t be read because it isn’t in the correct format.

whenever I try to use the JSON as shown in code below 

    func api(text: String){
        print(text)
        if let url = URL(string: "https://api.stackexchange.com/docs/search#order=desc&sort=activity&filter=default&site=stackoverflow") {
            var request = URLRequest(url: url)
            request.addValue("intitle", forHTTPHeaderField: text)
            request.httpMethod = "GET"
            print(request.description)
            let dataTask = URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
                //handle response here
                if let error = error {
                    
                    return
                }
                
                do {
                    
                    let json = try JSONSerialization.jsonObject(with: data!) as! [String: Any]
                    print(json)
                    
                } catch {
                    print(error.localizedDescription)
                }
            }
            dataTask.resume()
        }
    }

Any advice on what I'm doing wrong? I saw somewhere that the response was in GZip format so I tried using Alamofire because it should have some decompression for it, I thought, but still same issue.
