使用未申报类型的NSLinguisticTagScheme

Question

我的代码在操场的工作，和Xcode中显示没有错误，但是当我编译命令行上的文件时，它用错误

use of undeclared type NSLinguisticTagScheme 
and String has no member 'tokenType' 

继承人的问题代码回来。

let tagSchemes : [NSLinguisticTagScheme] = [ .tokenType] 
let tagger : NSLinguisticTagger = NSLinguisticTagger(tagSchemes: tagSchemes, options: 0) 
let options : NSLinguisticTagger.Options = [ .omitPunctuation, .omitWhitespace] 

tagger.string = text 
let range = NSRange(location: 0, length: text.utf16.count) 

tagger.enumerateTags(in: range, unit: .sentence, scheme: .tokenType, options: options, using: 
{ tag, tokenRange, stop in 
    let token = (text as NSString).substring(with: tokenRange) 
    sentences.append(token) 
}) 

任何想法？
