Is possible to convert Array to Set to use contains syntax(for string) in SWIFT ?

Question

For example I have:
array1 = [1, 2, 4, 6]
array2= [11,2, 45, 100 , 999]

I want to quit duplicates :)

Answer 1

Assuming it is removing duplicates across the two arrays? Try

var s = Set(array1)
s = s.union(array2)
