IOS developer (Full stack ** Urgent**----2

Looking for an IOS developer to implement UI and then to integrate API into it. I have the brief document prepared which i will show to the designated candidate. The developer is free to pick and chose either objective C or Swift in the IOS app development. If you are an outourcer or someone who works with an upfront payment, please don't bother bidding. The bidder must have adequate knowledge about XMPP server implementation and how to hook it with the backend language to expose the API. Although its not in the job description but it is mandatory to have technical knowledge about this domain so the chosen candidate can help my backend team whenever they are stuck or need some assistance. Only bid if you are 100% sure in terms of considering yourself fulfilling these requested high level specifications. No time wasters are allowed please. So the requested skill set is: 1) Swift/objC. 2) Front end development. 3) API integration 4) Technical knowledge of XMPP server implementation (It will be considered as a plus to get yourself hired for this task).
