How to remove duplicate elements from an array with Swift 5


Removing duplicates to get unique values out of an array can be a common task to perform.





Using removing duplicate elements from a Set :

  • A set is an unordered collection of unique elements.
  • Set does not contain any index or key to access an element.
  • Set is faster when iterating through the collection.
  • If you want there to be no duplicates and the order does not matter, you will use a set.


Using removing duplicate elements from an array :

  • An array is simply a container that can hold an ordered collection of similar elements.
  • Array elements are accessed using the index.
  • An array is bit slower when iterating through the collection.
  • If you want to use items order is important and can include duplicates so you should use an array.
