Question

我有一组元组（

 var array = [("John Doe", 13), ("The Guy", 15), ("The Person", 19)]

并希望按从最大到最小的int值对它们进行排序。最后，我希望数组看起来像这样

 var array = [("The Person", 19), ("The Guy", 15), ("John Doe", 13)]

我将如何做到这一点？

Answer 1

   var array = [("John Doe", 13), ("The Guy", 15), ("The Person", 19)]

    print("myStringArray: \(array)\n")
    array.sort {$0.1 > $1.1}
    print("myStringArray: \(array)\n")

Answer 2

您必须通过元组的Int值的$1值进行比较，检查此代码，对您有所帮助

        var tuplesArray : [(String,Int)] = [("John Doe", 13), ("The Guy", 15), ("The Person", 19)]
        let orderedTuples = tuplesArray.sorted { (value1, value2) -> Bool in
                return value1.1 > value2.1
        }

我希望这有助于你
