Hello
I fully read your description and have very interested in your project.
I developed iOS apps more than 5+ years and have submitted several apps and game apps on AppStore.
I have extensive knowledge about not only swift and obj-c, but also cocos2d-x.
You can find my game app on app store. It is CandyLegand, FarmLine, HundredBalls and so on.
I can handle this task for sure and I am looking forward to work with you to launch a great project.
Kindly initiate the chat to discuss in detail.
Regards
