如何查找重复数据存在于字典数组中。 [英] How to find duplicate data is present in array of dictionary.

问题描述

我有字典数组。如果字典数组中存在重复数据，那么将使用重复的元素名称引发一个标记。



字典数组如下：

[[project_code：1，lob：lob_1]，[project_code：1，lob：lob_1]，[project_code：2，lob：lob_1]，[project_code：3，lob：lob_1]]



这里我们需要循环查找相同的project_code和lob是否相同，然后它将返回所有重复的project_code。



重复数据意味着project_code和lob值对应相同。



在上面的数组中，如果我们通过那么它应该返回project_code： 1





如果有人可以在Swift中编写代码..



先谢谢。

I have array of dictionary. If duplicate data is present in the array of dictionary then a flag to be raised with the element name which is duplicate.

The array of dictionary is below:
[[project_code: 1, lob: lob_1], [project_code: 1, lob: lob_1], [project_code: 2, lob: lob_1], [project_code: 3, lob: lob_1]]

Here we need to loop through and find if same project_code and lob is same, then it would return which all project_code which are duplicate.

Duplicate data means the pair of project_code and lob value should be same.

In the above array, if we go through then it should return project_code : 1


If anyone can write a code in Swift ..

Thanks in Advance.
