如何用Int值對元組數組進行排序？

Question

我有元組（

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

的數組，並希望通過int值將會從最大到最小對它們進行排序。最後我想要的陣列看起來像這樣

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

如何我會做到這一點？

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

你必須比較，由$1值，元組的int值，檢查這個代碼，可以幫助你

 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 
     } 

我希望這有助於你
