iOS Social Messaging App Development

I’m building a social-networking app for iPhone and need an experienced Swift developer who can focus on a rich, real-time messaging module. The core of this first release is chat: users must be able to exchange text, voice, and video messages reliably and with a smooth, native iOS feel...
