language could not be found for tesseract in IOS (Swift)

Question

I am totally new to tesseract . So please don't mind if my question sounds a bit too nubby. I've downloaded tesseract using cocoapod and I've written the following code in my viewController :

import UIKit
import TesseractOCR


class ViewController: UIViewController ,G8TesseractDelegate {

    @IBOutlet weak var txtView: UITextView!


    override func viewDidLoad() {
        super.viewDidLoad()
        if  let tesseractOCR = G8Tesseract(language: "eng") {
            tesseractOCR.delegate = self
            tesseractOCR.image = UIImage(named: "test.png")?.g8_grayScale()
            tesseractOCR.recognize()


            txtView.text = tesseractOCR.recognizedText

        }




    }


    func progressImageRecognition(for tesseract: G8Tesseract!) {
        print("the regignision is in progress by \(tesseract.progress)+ %")
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

And then I went to the following link to download the English language . https://github.com/tesseract-ocr/tessdata/blob/master/eng.traineddata and then moved the downloaded file to my project as you can see in the image

Does any one know how can I fix this ? Here is the error in the console : Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory. Failed loading language 'eng' Tesseract couldn't load any languages!

The error says "tessdata" directory. You need to have a tessdata directory, in which the eng.traineddata file resides. This directory should be in the same directory as the tesseract executable. — sashoalm

The error says "tessdata" directory. You need to have a tessdata directory, in which the eng.traineddata file resides. This directory should be in the same directory as the tesseract executable.
