Nowadays in Swift you simply type
Set( yourArray ) to make an array unique. (Or an ordered set if needed.)
Before that was possible, how was it done?
I might have an array that looks like the following:
[1, 4, 2, 2, 6, 24, 15, 2, 60, 15, 6]
Or, really, any sequence of like-typed portions of data. What I want to do is ensure that there is only one of each identical element. For example, the above array would become:
[1, 4, 2, 6, 24, 15, 60]
Notice that the duplicates of 2, 6, and 15 were removed to ensure that there was only one of each identical element. Does Swift provide a way to do this easily, or will I have to do it myself?
