Alamofire 4.0与Swift 3的"没有成员"错误

Question

我在使用Swift 3.0时使用了Alamofire 4.0,但是遇到了以下代码的问题

类型'方法'(又名'OpaquePointer')没有成员'GET'

类型'方法'(又名'OpaquePointer')没有成员'PUT'

类型'方法'(又名'OpaquePointer')没有成员'POST'

类型'方法'(又名'OpaquePointer')没有成员'PATCH'

类型'方法'(又名'OpaquePointer')没有成员'DELETE'

枚举定义:

enum Method {
        case get
        case put
        case post
        case patch
        case delete

        func toAFMethod() -> Alamofire.Method {
            switch self {
            case .get:
                return Alamofire.Method.GET
            case .put:
                return Alamofire.Method.PUT
            case .post:
                return Alamofire.Method.POST
            case .patch:
                return Alamofire.Method.PATCH
            case .delete:
                return Alamofire.Method.DELETE
            }
        }
    }

基于Swift 3和Alamofire 4.0,API发生了重大变化:

import Alamofire

enum Method {
    case get
    case put
    case post
    case patch
    case delete

    func toAFMethod() -> Alamofire.HTTPMethod {
        switch self {
        case .get:
            return Alamofire.HTTPMethod.get
        case .put:
            return Alamofire.HTTPMethod.put
        case .post:
            return Alamofire.HTTPMethod.post
        case .patch:
            return Alamofire.HTTPMethod.patch
        case .delete:
            return Alamofire.HTTPMethod.delete
        }
    }
}
