Two presentations under the tree this month:

Jack Ryan

Rookie iOS developer. Day job is investments, not coding. Retired 40 year high school basketball official, developing app used by OHSAA tournament evaluators for tournament official assignments. Time sink #1: using segues in Storyboard from a containerView with modal presentations of a new view. Time sink #2: using protocols and delegates within a containerView.

Many of us have followed Jack’s progress in developing his iPad app and it’s been great to see the progress.

Eric Downey

ARKit in iOS! Let’s break it down into it’s smallest components to examine how to use each one effectively. Then let’s see what it takes to combine these components into one cohesive augmented reality experience. We’ll run through the basics of ARKit including plane detection and face tracking, then move to more advanced techniques such as object scanning and detection. We’ll then combine these into one app to show the full power of ARKit.

Eric is a Software Development Consultant and Mobile Tech Lead located in Columbus, OH. He has spent the last 5 years working for Information Control Company, primarily focused on mobile development, including native iOS and web front-end technologies. In his spare time, he continues his work on iOS having spent 8 years developing iOS apps. After authoring a book on Swift development, he has moved into writing articles about Swift and iOS on Medium for the publication Swift2Go. Other than writing code, he enjoys reading comic books and playing video games.
