Irving-iOS-Jumpstart Meetup presentation of a useful breakdown of the realms of developing in iOS. Provides sample resources for learning applicable to each realm.

1. 5 Realms
for Learning iOS Development

2. 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.

3. 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

4. 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

5. 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

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