To remove the first node of a linked list in Swift, you need to update the head property of the linked list to point to the second node. The first node can be deallocated by removing all references to it. Here is an example of how to remove the first node of a linked list in Swift:
main.swift216 chars17 lines
In the removeFirst()
method, we update the head to point to the second node in the linked list by setting it to head?.next
. If the linked list is empty, head
will be nil
. The first node is automatically deallocated by removing all references to it.
