NSLinguisticTagger is deprecated. Using NLTagger instead. (iOS 12.0+, macOS 10.14+)

import NaturalLanguage

var str = "I want to split a paragraph into sentences. But, there is a problem. My paragraph includes dates like Jan.13, 2014 , words like U.A.E and numbers like 2.2. How do i split this."

func splitSentenceFrom(text: String) -> [String] {
    var result: [String] = []
    let tagger = NLTagger(tagSchemes: [.lexicalClass])
    tagger.string = text
    tagger.enumerateTags(in: text.startIndex.. Bool in
        result.append(String(text[tokenRange]))
        return true
    }
    return result
}

let sentences = splitSentenceFrom(text: str)

sentences.forEach {
    print($0)
}

output:

I want to split a paragraph into sentences. 
But, there is a problem. 
My paragraph includes dates like Jan.13, 2014 , words like U.A.E and numbers like 2.2. 
How do i split this.

want to exclude empty sentences and trim whitespace? add this

let sentence = String(text[tokenRange]).trimmingCharacters(in: .whitespacesAndNewlines)
if sentence.count > 0 {
    result.append(sentence)
}
