add an element to the end of an array in swift

You can add an element to the end of an array in Swift using the append method. Here's an example:

main.swift
var myArray = [1, 2, 3]
myArray.append(4)

print(myArray) // Output: [1, 2, 3, 4]
82 chars
5 lines

In this example, we have an array called myArray containing the values 1, 2, and 3. We then use the append method to add the value 4 to the end of the array. Finally, we print the contents of the array to the console, which will show that 4 has been successfully added to the end of the array.
