Swift方法需要分隔符

Question

我创建了以下方法：

class func getAEDbyReference(reference: String, completionHandler: (Result<AED, NSError>) -> Void {
    Alamofire.request(Router.GetAED(reference)).responseObject{(response: Response<AED, NSError>) in
        completionHandler(response.result)
}

我得到的错误是：Expected ',' separator

但为什么呢？我没有看到错误

Answer 1

在Void

之后加上右括​​号

class func getAEDbyReference(reference: String, completionHandler: (Result<AED, NSError>) -> Void) {
    Alamofire.request(Router.GetAED(reference)).responseObject{(response: Response<AED, NSError>) in
    completionHandler(response.result)
}
