Swift: remove all whitespace characters from a string

Question

I'd like to use CharacterSet.whitespacesAndNewlines to remove whitespace from a string.

However, the code below does not compile.

myString.replacingOccurrences(of: CharacterSet.whitespacesAndNewlines, with: "")
// Instance method 'replacingOccurrences(of:with:options:range:)' requires that 'CharacterSet' conform to 'StringProtocol'

What is a simple way to achieve the intended result?

Answer 1

You can use

let result = myString.filter { !$0.isWhitespace }
