Swift 검색api 사용

let url = URL(string:“https://dapi.kakao.com/v3/search/book?target=title&query=java”)
//print(url!)

    let request = Alamofire.request(url!, method: .get, encoding: JSONEncoding.prettyPrinted, headers: ["Authorization": "KakaoAK RestAPI앱키"])
    request.responseJSON{response in
        print(response.result.value!)

        let data = try! Data(contentsOf: url!)
        print(data)
        let result = try! JSONSerialization.jsonObject(with: data, options: []) as! [String:Any]
        print(result)
        
        let document = result["documents"] as! NSArray
        
        for index in 0...(document.count - 1){
            let documents = document[index] as! NSDictionary
            self.titles.append(documents["title"] as! String)
            self.authors.append(documents["authors"] as! String)
        }
        print(self.titles)
        print(self.authors)
    }
    
    tableView.dataSource = self
}

result에서 [“message”: cannot find appkey, “errorType”: AccessDeniedError]가 출력이 되는데 헤더를 잘못작성한건가요?

해결하였습니다.
