How to remove multiple spaces in Strings with Swift 2

Question

Until Swift 2 I used this extension to remove multiple whitespaces:

func condenseWhitespace() -> String {
        let components = self.componentsSeparatedByC         


        

Answer 1

SWIFT 3: Cleaner version

extension String {
    var condensedWhitespace: String {
        let components = self.components(separatedBy: .whitespacesAndNewlines)
        return components.filter { !$0.isEmpty }.joined(separator: " ")
    }
}
