Insert An Element At The End Of An Array In Swift

Working with arrays is a fundamental skill in any programming language and Swift is no exception. In this article, we will walk you through on how to insert an element at the end of an array in Swift, an efficient method that can come in handy in many situations.

Code snippet: Insert An Element At The End Of An Array In Swift

Here’s a simple code snippet in Swift to insert an element at the end of an array:

var array = [1, 2, 3]
array.append(4)
print(array)

Output:

[1, 2, 3, 4]

Code Explanation for Inserting An Element At The End Of An Array In Swift

The above Swift code explains the addition of an element at the end of an array using the append() method.

Here’s a step by step explanation:

First, we create an array containing the elements 1, 2 and 3:

var array = [1, 2, 3]

Next, we call the append() function on our array to add a new element at the end. In this case, we’re adding the number 4:

array.append(4)

The append() function is a built-in Swift function for arrays, which allows you to add a new element at the end of the array.

Finally, we print the array to see the result of our operation:

print(array)

The output will be:

[1, 2, 3, 4]

It shows that our array has successfully included 4 at its end, indicating our append operation was successful.

In summary, Swift’s append() function allows you to add elements at the end of an array in an intuitive and straightforward manner. This makes manipulating arrays in Swift both efficient and approachable even for beginners.
