根据您的问题，您希望在Swift中使用字典数组， 这是实现相同目标的简单方法：

  var arrayOfDict = [[String: String]]()

//creating dictionaries      
         let dict1 = ["name" : "abc" , "city" : "abc1"]
         let dict2 = ["name" : "def" , "city" : "def1"]
         let dict3 = ["name" : "ghi" , "city" : "ghi1"]
         let dict4 = ["name" : "jkl" , "city" : "jkl1"]

//Appending dictionaries to array

         arrayOfDict.append(dict1)
         arrayOfDict.append(dict2)
         arrayOfDict.append(dict3)
         arrayOfDict.append(dict4)


//accessing each and every element of the arrayOfDictionary

         for dict in arrayOfDict{
              for (key, value) in dict {
                   print("the value for \(key) is = \(value)")
              }
         }
