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.
