You can enumerate String per sentences by using NSStringEnumerationOptions.BySentences. But it detect a "sentence" only if the first character is upper-cased.

So, This may not be perfect, but you can try this: 

import Foundation

let text:String = "lorem ipsum dolor elit, sed aliqfuas. imfs enim ad veniam, quis nostrud consequat? duis aute irure dolor in pariatur."

var result = ""
text.uppercaseString.enumerateSubstringsInRange(text.startIndex..<text.endIndex, options: .BySentences) { (_, range, _, _) in
//  ^^^^^^^^^^^^^^^^ enumerate all upper cased string

    var substring = text[range] // retrieve substring from original string

    let first = substring.removeAtIndex(substring.startIndex)
    result += String(first).uppercaseString + substring
}

// result -> "Lorem ipsum dolor elit, sed aliqfuas. Imfs enim ad veniam, quis nostrud consequat? Duis aute irure dolor in pariatur."

public static void main(String[] args) {
    String a = "this is.a good boy";
    String[] dot = a.split("\\.");
    int i = 0;
    String output = "";
    while (i < dot.length) {
        dot[i] = String.valueOf(dot[i].charAt(0)).toUpperCase()
                + dot[i].substring(1);
        output = output + dot[i] + ".";
        i++;
    }
    System.out.println(output);
}
