This String extension (Swift 4.2) will help convert an invalid iOS file name to a valid iOS file name.

 extension String {
    func convertToValidFileName() -> String {
        let invalidFileNameCharactersRegex = "[^a-zA-Z0-9_]+"
        let fullRange = startIndex..

For example

"name.name?/!!23$$@1asd".convertToValudFileName()       // "name-name-23-1asd"

"!Hello.312,^%-0//\r\r".convertToValidFileName()        // "-Hello-312-0-"

"/foo/bar/pop?soda=yes|please".convertToValidFileName() // "-foo-bar-pop-soda-yes-please"
