I could not follow up much with openCV tutorials, Is there xCode, iOS project downloads available of those tutorials mentioned in the openCV tutorial link :http://docs.opencv.org/3.0-last-rst/doc/tutorials/ios/table_of_content_ios/table_of_content_ios.html#table-of-content-ios. So I could understand better ? Or any other materials to learn using openCV with xCode iOS apps ?
