To get the union of two sets in Swift, you can use the union method provided by the Set class. Here's an example:

`main.swift232 chars7 lines`

In the example above, we have two sets `set1`

and `set2`

with some overlapping elements. We use the `union`

method to get a new set that contains all the unique elements from both sets.

If you have two arrays and want to get the union of their elements, you can create sets from the arrays and use the same `union`

method. Here's an example:

`main.swift196 chars10 lines`

In the example above, we first convert the arrays `array1`

and `array2`

into sets `set1`

and `set2`

using the `Set`

constructor. We can then use the `union`

method to get a new set that contains all the unique elements from both arrays.
