参数标签 (_:, destination) 与可用重载不匹配

Question

我正在尝试将我的代码从 Swift 2 迁移到 Swift 3。这是我使用 Alamofire 恢复数据的代码：

public func download(resumeData: NSData, destination: Request.DownloadFileDestination) -> Request {
    return download(.ResumeData(resumeData), destination: destination)
}

在构建时它显示错误为：

Argument Labels (_:, destination) do not match available overloads

Answer 1

这是 swift 3.0

的正确迁移

        let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)

        Alamofire.download(resumingWith: Data, to: destination)

参数标签 (_:, destination) 与可用重载不匹配

Argument Labels (_:, destination) do not match available overloads

swift

alamofire
