struct CursValutar: Codable {
let curs: [Currency]
}
struct Currency: Codable {
let symbol: String
let value: Double
}我尝试了一些pod，但没有成功。

您可以使用XMLMapper。您的模型将如下所示：
struct DataSet: XMLMappable {
var nodeName: String!
var cursValutar: CursValutar?
init?(map: XMLMap) {}
mutating func mapping(map: XMLMap) {
cursValutar <- map["Body.Cube"]
}
}
struct CursValutar: XMLMappable {
var nodeName: String!
var curs: [Currency]?
init?(map: XMLMap) {}
mutating func mapping(map: XMLMap) {
curs <- map["Rate"]
}
}
struct Currency: XMLMappable {
var nodeName: String!
var symbol: String?
var value: Double?
init?(map: XMLMap) {}
mutating func mapping(map: XMLMap) {
symbol <- map.attributes["currency"]
value <- map.innerText
}
}您可以像这样获取和映射这个XML：
AF.request(url).responseString { (dataResponse: AFDataResponse<String>) in
switch dataResponse.result {
case .success(let xmlString):
let dataSet = XMLMapper<DataSet>().map(XMLString: xmlString)
print(dataSet?.cursValutar?.curs?.first?.value)
case .failure(let error):
print(error)
}

我建议使用像XMLCoder这样的库，然后可以在Alamofire的responseDecodable中使用它
// Make XMLDecoder conform to Alamofire's DataDecoder protocol.
extension XMLDecoder: DataDecoder {}
// Then you can use it to decode responses.
AF.request(...).responseDecodable(of: SomeType.self, decoder: XMLDecoder()) { response in
//...
