How to Iterate over a Two Dimensional Array in Swift ?

Answer

To iterate over a Two Dimensional Array in Swift, you can use nested loops.

✐ Examples

1 Iterating over a 2D Array of Integers

In this example,

We declare and initialize a 2D array of integers named matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

Swift Program

let matrix = [[0, 1, 2], [1, 2, 3], [2, 3, 4]]
for row in matrix {
    for element in row {
        print(element, terminator: " ")
    }
    print()
}

Output

0 1 2 
1 2 3 
2 3 4

2 Iterating over a 2D Array of Strings

In this example,

We declare and initialize a 2D array of strings named matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

Swift Program

let matrix = [["Hello", "World"], ["Swift", "Programming"]]
for row in matrix {
    for element in row {
        print(element, terminator: " ")
    }
    print()
}

Output

Hello World 
Swift Programming
