add an element to the beginning of an array in swift

To add an element at the beginning of an array in Swift, you can use the insert(_:at:) method or the append(_:) method, followed by the use of the reverse() method to reverse the array's order. Here's an example:

main.swift
var myArray = [2, 3, 4, 5]
myArray.insert(1, at: 0)
// myArray is now [1, 2, 3, 4, 5]

// Alternatively, you can use the append method followed by the reverse method:
myArray.append(0)
myArray = myArray.reversed()
// myArray is now [0, 1, 2, 3, 4, 5]

In the first example, the insert(_:at:) method takes two parameters: the element to be inserted (in this case, 1), and the index at which to insert it (which is 0 for the beginning of the array). This shifts all the other elements one index to the right.

In the second example, append(_:) is used to add the new element 0 to the end of the array. Then, the reversed() method is used to reverse the order of the elements in the array, so the new element now appears at the beginning.
