Swift: Merge 2 Integer Arrays

Merging two integer arrays in Swift is straightforward and can be done using the array concatenation operator. This approach creates a new array containing all elements from both input arrays in order. It is useful when you want to combine data from multiple sources into a single collection.

Code

// Define two integer arrays
let array1 = [1, 2, 3]
let array2 = [4, 5, 6]

// Merge arrays using the + operator
let mergedArray = array1 + array2

// Print the merged array
print(mergedArray)  // Output: [1, 2, 3, 4, 5, 6]

Key Points

• Use the + operator to concatenate two arrays in Swift easily.
• The merged array contains elements from the first array followed by the second.
• The original arrays remain unchanged after merging.
• This method works efficiently for arrays of any size and type.
