How to trim whitespace in a string
Swift version: 5.0
It's not hard to trim whitespace from a string in Swift, but the syntax is a little wordy – or "self-descriptive" if you're feeling optimistic. You need to use the trimmingCharacters(in:) method and provide a list of the characters you want to trim. If you're just using whitespace (tabs, spaces and new lines) you can use the predefined whitespacesAndNewlines list of characters, like this:
let str = " Taylor Swift "
let trimmed = str.trimmingCharacters(in: .whitespacesAndNewlines)That will set trimmed to be "Taylor Swift”.
