Swift 4的swagger-codegen生成的代码中的错误

Question

我有一个新项目，其中所有REST代码都是由swagger-codegen生成的，这是我以前从未使用过的。 除了requestBuilder初始化错误外，其他一切似乎都正常

Cannot convert value of type 'RequestBuilder<_>.Type' to specified type 'RequestBuilder<MyGeneratedModel>.Type'

要求建造者：

let requestBuilder: RequestBuilder<TimeoutForNextRequestInSeconds>.Type = SwaggerClientAPI.requestBuilderFactory.getBuilder()

requestBuilderFactory：

open static var requestBuilderFactory: RequestBuilderFactory = AlamofireRequestBuilderFactory()

AlamofireRequestBuilderFactory：

class AlamofireRequestBuilderFactory: RequestBuilderFactory {
    func getNonDecodableBuilder<T>() -> RequestBuilder<T>.Type {
        return AlamofireRequestBuilder<T>.self
    }

    func getBuilder<T:Decodable>() -> RequestBuilder<T>.Type {
        return AlamofireDecodableRequestBuilder<T>.self
    }
}

public protocol RequestBuilderFactory {
    func getNonDecodableBuilder<T>() -> RequestBuilder<T>.Type            
    func getBuilder<T:Decodable>() -> RequestBuilder<T>.Type
}

你猜怎么着？
