Merge Two Arrays Together In Swift

Swift is a powerful programming language developed by Apple, oftentimes employed in iOS development. One commonly encountered task in Swift, especially in dealing with data-driven application, is merging two arrays together. This article will provide a step-by-step tutorial on how to do just that.

Code Snippet: Merging Two Arrays

In Swift, merging two arrays is a straightforward process. Here is a simple example:

let array1 = [1, 2, 3]
let array2 = [4, 5, 6]
let mergedArray = array1 + array2

print(mergedArray)

When this code is run, it will output: [1, 2, 3, 4, 5, 6].

Code Explanation: Merging Two Arrays

In the code snippet above, we have two arrays, array1 and array2, each holding three integer values. The goal is to merge these two arrays into one.

The first line declares an array named array1 and assigns it the values 1, 2, and 3. Similarly, on the second line, we declare another array array2 and assign it the values 4, 5, and 6.

Now that we have our two arrays, we want to combine them. The third line demonstrates how straightforward this task is in Swift: the + operator is applied between two arrays to concatenate them. Thus, let mergedArray = array1 + array2 creates a new array that combines the elements of array1 and array2.

Finally, we print mergedArray with the print(mergedArray) command. This outputs the consolidated array [1, 2, 3, 4, 5, 6] into your console.

In a nutshell, merging two arrays in Swift is a breeze thanks to the friendly + operator. This merely scratches the surface of what’s possible with arrays in Swift, however.
