Get the text count from image iOS swift

Solution:

In iOS it had an option named CIDetector to detect the text count that was appeared in an image.

//    MARK: - TextCount

    func getTextCount(from img: UIImage?) -> Int {

        

        let detector = CIDetector(ofType: CIDetectorTypeText, context: nil, options: [CIDetectorAccuracy: CIDetectorAccuracyLow])

        var ciImage: CIImage? = nil

        if let anImage = img?.cgImage {

            ciImage = CIImage(cgImage: anImage)

        }

        // retrive array of CITextFeature

        var features: [CIFeature]? = nil

        if let anImage = ciImage {

            features = detector?.features(in: anImage, options: [CIDetectorReturnSubFeatures: false])

        }

        return features?.count ?? 0

    }
