Removing duplicate elements from an array in Swift
问题 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?
