nextWord(from:forward:)
Returns the index of the first character of the word after or before the specified index.
Declaration
func nextWord(from location: Int, forward isForward: Bool) -> IntParameters
Return Value
true if this is the first character after index that begins a word; if flag is false, it’s the first character before index that begins a word, whether index is located within a word or not.
Discussion
If index lies at either end of the string and the search direction would progress past that end, it’s returned unchanged.
This method is intended for moving the insertion point during editing, not for linguistic analysis or parsing of text.
Raises an rangeException if index lies beyond the end of the receiver’s characters.
