How to count the white spaces in a string in Swift

Answer 1

func countWhitespaceCharacters(_ str: String) -> Int {
    var count = 0
    
    for ch in str {
        if ch.isWhitespace {
            count += 1
        }
    }
    
    return count
}

let str = "Swift \n  Programming \r Language \t "
