Me and my team have good experience with Swift, Objective C and Xcode. However, Your project description doesn't contain a detailed information about the project. So for now, I will just introduce myself. I am a fast coder and usually write bug-free code. I won over 35 competitions in algorithms and development. I also have a team of excellent coders and UI designers who provide work with lightening speed. No upfront milestones or payments required to start the work :). However, milestones will have to be paid in stages after each measurable step is completed and working. I will be providing you a breakdown of the project and its measurable stages. The work that I have been doing is displayed in my profile, and I believe I can handle your project well. Please visit my profile at freelancer.com/u/allenross356.html and you will be able to see that I have completed above 110 projects so far with excellent ratings. I reply within 24 hours. Please let me know if you would like to hire me. Thanks.
