I need to get stem of word. So i can't get if lemma scheme doesn't exist for english.
Here's the code that i'm testing available tag schemes :
let tagSchemes = NSLinguisticTagger.availableTagSchemes(forLanguage: "en")
print(tagSchemes)
and this is output:
[__C.NSLinguisticTagScheme(_rawValue: TokenType),
__C.NSLinguisticTagScheme(_rawValue: Language),
__C.NSLinguisticTagScheme(_rawValue: Script)]
Notice that, simulators will return all scheme. My issue is on my device. You can try 'fr' or 'de' except 'en'.
