How to remove first element from array in Swift?

To remove the first element from an array in Swift, you can use the removeFirst() method. Here's an example:

1
2
3

var numbers = [1, 2, 3, 4, 5]
numbers.removeFirst()
print(numbers) // Output: [2, 3, 4, 5]

Alternatively, you can also use subscript syntax to remove the first element:

1

3
4
5

var numbers = [1, 2, 3, 4, 5]
if !numbers.isEmpty {
    numbers.remove(at: 0)
}
print(numbers) // Output: [2, 3, 4, 5]

Both of these methods will remove the first element from the array.
