Using regex in Swift

Question

I\'m trying to replace the occurrences of all spaces and special characters within a string in Swift.

I don\'t know what the RegEx would be in Swift.

I am tr

Additionally, you could extend String and accomplish the same bit. But if it's homework and they said function stick with that.

var word = "Hello World!!!"

extension String {
    func regEx() -> String {
        return self.replacingOccurrences(of: "\\W+", with: "", options: .regularExpression, range: nil)
    }
}

word.regEx()
