ios – NLTagger tags each phrase as OtherWord and title scheme as Different

I attempted Apple’s personal instance:

import NaturalLanguage

let textual content = "The American Crimson Cross was established in Washington, D.C., by Clara Barton."

let tagger = NLTagger(tagSchemes: [.nameType])
tagger.string = textual content

let choices: NLTagger.Choices = [.omitPunctuation, .omitWhitespace, .joinNames]
let tags: [NLTag] = [.personalName, .placeName, .organizationName]

tagger.enumerateTags(in: textual content.startIndex..<textual content.endIndex, unit: .phrase, scheme: .nameType, choices: choices) { tag, tokenRange in 
    // Get the almost definitely tag, and print it if it is a named entity.
    if let tag = tag, tags.comprises(tag) {
        print("(textual content[tokenRange]): (tag.rawValue)")
    }
        
    // Get a number of attainable tags with their related confidence scores.
    let (hypotheses, _) = tagger.tagHypotheses(at: tokenRange.lowerBound, unit: .phrase, scheme: .nameType, maximumCount: 1)
    print(hypotheses)
        
   return true
}

However it returns all title tags as Different. I additionally tried one other instance of tagging the sentence with lexical class, and it additionally tags each phrase as OtherWord:

var textual content = "The American Crimson Cross was established in Washington, D.C., by Clara Barton."

let tagger = NLTagger(tagSchemes: [.lexicalClass])
tagger.string = textual content

let choices: NLTagger.Choices = [.omitPunctuation, .omitWhitespace, .joinNames]

print("language", tagger.dominantLanguage)

tagger.enumerateTags(in: textual content.startIndex..<textual content.endIndex, unit: .phrase, scheme: .lexicalClass, choices: choices) { tag, tokenRange in
    // Get the almost definitely tag, and print it if it is a named entity.
    if let tag = tag {
        print("(textual content[tokenRange]): (tag.rawValue)")
    }

   return true
}

I attempted the reply for this query by setting language orthography but it surely did not assist:

//tagger.setOrthography(NSOrthography(dominantScript: "Latn", languageMap: ["Latn": ["en"]]), vary: textual content.startIndex..<textual content.endIndex)
tagger.setOrthography(NSOrthography.defaultOrthography(forLanguage: "en-US"), vary: textual content.startIndex..<textual content.endIndex)

Anyone has a clue why is it like this?

By the way in which, my Xcode model is the most recent one as of right now, 14.3.
