如何用Int值对元组数组进行排序？

Question

我有元组（

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

的数组，并希望通过int值将会从最大到最小对它们进行排序。最后我想要的阵列看起来像这样

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

如何我会做到这一点？

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

你必须比较，由$1值，元组的int值，检查这个代码，可以帮助你

 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
