Answer

To create a Three Dimensional Array in Swift, you can use array initialization with specified dimensions.

✐ Examples

1 Creating a 3D Array with Array Initialization

In this example,

We use array initialization with specified dimensions to create a 3D array.
The first dimension represents the outer array, the second dimension represents the middle array, and the third dimension represents the inner array.

Swift Program

// Creating a 3D Array with Array Initialization
var threeDArray = [[[Int]]](repeating: [[Int]](repeating: [Int](repeating: 0, count: 4), count: 2), count: 3)
// Modify an element
threeDArray[1][0][2] = 5
// Print the array
print(threeDArray)

Output

[[[0, 0, 0, 0], [0, 0, 0, 0]], [[0, 0, 5, 0], [0, 0, 0, 0]], [[0, 0, 0, 0], [0, 0, 0, 0]]]

Summary

In this tutorial, we learned How to create a Three Dimensional Array in Swift language with well detailed examples.
