Does Swift have a trim method on String?

Does Swift have a trim() method on String? For example:

let result = " abc ".trim()
// result == "abc"
Solution

  • Here's how you remove all the whitespace from the beginning and end of a String.

    (Example tested with Swift 2.0.)

    let myString = "  \t\t  Let's trim all the whitespace  \n \t  \n  "
let trimmedString = myString.stringByTrimmingCharactersInSet(
    NSCharacterSet.whitespaceAndNewlineCharacterSet()
)
// Returns "Let's trim all the whitespace"

    (Example tested with Swift 3+.)

    let myString = "  \t\t  Let's trim all the whitespace  \n \t  \n  "
let trimmedString = myString.trimmingCharacters(in: .whitespacesAndNewlines)
// Returns "Let's trim all the whitespace"
