Question

struct Response: Codable {
    let status: String
    let value: [Value]
}
struct Value: Codable {
    let psid: Int
    let name: String
    let valute: String
    let reserve: Double
    let with_codes: Int
    let img: String
}

var good = [Value]()//first array



struct Response1: Codable {
    let status: String
    let value: [Value1]
}
struct Value1: Codable {
    let id: String
    let enabled: Int
    let direct: Int
    let psid1: Int
    let psid2: Int
    let in: Int
    let in_valute: String
    let out: Double
    let out_valute: String
    let in_min: Double
    let in_max: Int
    let reserve: Double
}

var good1 = [Value1]()//second array


good.forEach { goodItem in
  if good1.contains(where: { good1Item -> Bool in
    return good1Item.psid2 == goodItem.psid
  }) {
    print(goodItem)
  }
}

问题是，当我需要将goodItem.name输出到表时，只输出最后一个值，虽然当我检查控制台中的所有内容时，google我发现return方法只返回最后一个值，怎么能我解决了吗？

这对我有用：

for value in good {
  if good1.filter( {$0.psid2 == value.psid}).count > 0 {
    print(value.name)
  }
}

forEach循环的问题
