I have been engaged in the development of iPhone approximately five years. I have excellent experience in developing iPhone app in many forms, including the web service developed in the rest of the way. My basic skill is objective-c, swift, xamarin and WCF. Recent years I have a great attraction to jumping smoothly into the swift excellence and has invested a lot of time to develop with the swift language. I think that is an important guarantee for a rich development experience to lead the project to success. Thank you for reading my article.
