In 2014, Facebook brought us Flux and with it, the idea of unidirectional data flow. Allied with React, Flux and its variations took the Web World by storm. Today's mobile apps also rely heavily on data handling so why not apply the same principles to it? This talk is aimed at the mobile community, specifically the iOS community. It is supposed to be an intro to the unidirectional data flow pattern, cover the basics of how to use Flux and Redux on iOS and share my experience in applying it to existing code, its benefits and pitfalls.
