在Swift3中,我之前使用以下方法将Bool转换为Int

let _ = Int(NSNumber(value: false))

转换为Swift4后,我得到了一个"'init'被弃用"警告.怎么办呢？

我对这篇文章的问题非常相似,但我不完全理解答案.我已经创建了一个完成处理程序,但它似乎没有按预期工作.

func updateTeam(teamID: Int) {
    startConnection {NSArray, Int in
        //Do things with NSArray
    }
}

func startConnection(completion: (NSArray, Int) -> Void) {
    let url = URL(string: "http://www.example.com/path")

    request.httpMethod = "POST"
    let postString = "a=\(Int(teamInput.text!)!)"
    request.httpBody = postString.data(using: .utf8)

    let dataTask = URLSession.shared.dataTask(with: request) {
        data,response,error in
        print("anything")
        do {
            if let jsonResult = try JSONSerialization.jsonObject(with: data!, options: []) as? NSDictionary {
                self.teamResult = jsonResult
                print(jsonResult)
            }
        } catch let error as …
