How do I make a exact duplicate copy of an array?

Question

How would I make an exact duplicate of an array?

I am having hard time finding information about duplicating an array in Swift.

I tried using .copy()

Nate is correct. If you are working with primitive arrays all you need to do is assign duplicateArray to the originalArray.

For the sake of completeness, if you were working an NSArray object, you would do the following to do a full copy of an NSArray:

var originalArray = [1, 2, 3, 4] as NSArray

var duplicateArray = NSArray(array:originalArray, copyItems: true)
