How to trim start and end of string in Swift?

Question

I'd like to trim / from the beginning and end of a string in Swift. Is there anything built or for this or what's a good way to do this?

Answer 1

I like to use stringByTrimmingCharactersInSet in such cases, with a custom character set (here just "/"):

let original = "/word/"
let result = original.stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "/"))

Result: "word"
