This works
let replaced = String(map(aString.generate()) {
$0 == " " ? "-" : $0 })
and this doesn't
let replaced = String(map(aString.generate()) {
$0 == " " ? "" : $0 })
Why?

Use the String. replace() method to remove all whitespace from a string, e.g. str. replace(/\s/g, '') . The replace() method will remove all whitespace characters by replacing them with an empty string.
In the Swift string, we check the removal of a character from the string. To do this task we use the remove() function. This function is used to remove a character from the string. It will return a character that was removed from the given string.
Swift String – Remove Specific Characters To remove specific set of characters from a String in Swift, take these characters to be removed in a set, and call the removeAll(where:) method on this string str , with the predicate that if the specific characters contain this character in the String.
To remove leading and trailing spaces, we use the trimmingCharacters(in:) method that removes all characters in provided character set. In our case, it removes all trailing and leading whitespaces, and new lines.
For Swift 5:
" spaces here ".replacingOccurrences(of: " ", with: "")
returns:
"spaceshere"
