How to enumerate a zip array in swift 4 to get index for each object

Question

I need to enumerate a zipped array to check index for each object from array. Below is my code please help me out.

for((index1, index2),(value1, value2)) in zip(array1, array2).enumerated() {
        // INDEX OF OBJECT
}

Answer 1

一旦你压缩了数组，它就只有一个索引。只需将其用作普通枚举即可。

let arr1 = ["1","2","3"]
let arr2 = ["A","B"]
let arr3 = zip(arr1, arr2)
print(arr3)

for (index, (x,y)) in arr3.enumerated() {

    print(index, y)

}

享受！
