Question

我有一个带有重复主键和空主键的API。我如何删除那些重复的id，以便我可以将它插入数组并在Swift的tableview中显示？

这是上述链接的输出：

{
  "id": 7,
  "name": "Raghuram Rajan",
  "skills": " Economist",
  "image": "https://teekhapan.files.wordpress.com/2012/08/raghuram-rajan.jpg?w=229&h=300"
},
{
  "skills": "Dancer"
},
{
  "id": 8,
  "name": "Raghuram Rajan",
  "skills": " Economist",

您可以在班级中使用Equatable

class yourClass: Equatable {
    var id :Int = 0
    static func ==(lhs: yourClass, rhs: yourClass) -> Bool {
        return lhs.id == rhs.id
    }
}

然后在将新obj附加到数组之前检查它是否包含obj。
