Confirm whether Tinder API based dating app existing source works and add a chat functionality there

Hello everyone! I'm looking for an experienced iOS app developer who can lead this project to the completion in the future not only working on this small piece of work. I've a working source code of dating app which utilizes Tinder APIs instead of its own server. In detail, the app uses Facebook accounts which are registered at Tinder. It also uses Tinder APIs for all communications. I know that it works well for authentication, login, recommendation, swipe & settings but chat functionality still doesn't work even though there's some code snippet for chat functionality. What I'm aiming is to 1. Confirm whether current source works well. 2. Make the chat functionality work. I can provide you with the source code and related documentations. ** I attached the source code here already. You should register your or dummy Facebook account at Tinder for testing. As I mentioned above, I'll let you work on this project for the implementation of further functionalities. I like only honest developers. Please bid with reasonable amount and timeline. In my thought, it's only 1 day working or so at the moment. Thanks in advance. Lay Wang.
