Continuous Delivery in Mobile

Continuous Delivery in Mobile has always been a challenge in the Past, between the strict regulations of Apple's AppStore and the build tools lagging behind.

This is a look at how quickly mobile is catching up to web for continuous delivery and how you can get your team to smooth frequent releases.

I presented this talk at Houston TechFest 2016

17. Copyright 2016 by Venkat Palivela HURDLES Not all deploys 
 are the same “Oh, lets upgrade the networking framework” Risk hedging 
 is common “We use toggles to a lot and
 tend to keep them longer than we need to” Conventions are 
 everywhere “I know this framework does it, but I want something smaller so we’ll write one” * Richard Cook, Velocity Conference 2016
