## Discussion

Discussion Use this linguistic unit to tokenize text into sentences, like in the following example: let text = "This is a sentence. This is another sentence."      let tokenizer = NLTokenizer(unit: .sentence) tokenizer.string = text      let range = text.startIndex..<text.endIndex      let tokenArray = tokenizer.tokens(for: range) print("Number of tokens: \(tokenArray.count)")      tokenizer.enumerateTokens(in: range) { tokenRange, _ in     print(text[tokenRange])     return true } For more information, see Tokenizing natural language text.
