5 Realmsfor Learning iOS Development

Summary

• To the beginning iOS developer the formalities of classes, frameworks, design patterns, and learning an all new integrated development environment can be overwhelming.

• Today we'll discuss a useful breakdown of the realms of developing in iOS and provide resources for learning applicable to each realm.

My Background• Owned first generation iPhone in 2007

• iOS Developer since 2010.

• Self taught iOS programmer

• Introduction of the iPad pushed me into learning how to program for business use

• Published first app to Apple app store in 2011

My Motivation

• increase mobile literacy - mobile is a different animal

• to sample reality for Veray Intelligence

• if you really want to know something, teach it

My Motivation

• I recall my pain in 2010-2011

• when beginning iOS development it's easy to get utterly stuck and want to give up on learning

Goal For Today

• Knowing which realm you're having trouble in really helps in finding the solution and getting unstuck in your learning efforts.
