Swift was founded by Remko Tronçon and Kevin Smith, both co-authors of XMPP: The Definitive Guide and long-time members of the XMPP community, in an effort to create a better messaging client for users who want or need to access servers running with the standard XMPP protocols and who want a client that’s easy to use, responsive and unobtrusive. Since then the Swift ecosystem of software has grown to include XMPP libraries for multiple languages/platforms and assorted smaller XMPP tools.

Remko Tronçon

Remko started out in the XMPP world by contributing patches to the Psi chat client in 2003, becoming part of the core development team a year later. He has been an active member of the XMPP Standards Foundation since then, writing several XMPP Extension Protocols, and serving on the XSF council for a while. Besides his work in XMPP, he did a PhD about virtual machine and compiler optimization for data mining applications.

Kevin Smith

Kev started his XMPP journey in 2001 and by 2002 was contributing patches to the Psi client, of which he became project leader in 2004. He has been a member of the XMPP Standards Foundation for many years, has spent a number of recent years as Chair of the XMPP Council and has authored several XMPP Extension Protocols. He works for Isode where he primarily works on the M-Link XMPP server and associated tools. As well as his long-term interest in XMPP he has a PhD from studying multi-objective optimisation techniques and has worked, and maintains an interest, in machine learning.


In the meantime, the Swift projects have had contributions from many other people, whom we would like to thank:
