Course No. N/A

This course is designed to train both novice and experienced developers how to create native iOS 10 Apps for iPhone, iPad and iPod using the Objective-C programming language. Created by experienced iOS developers, the course places a very strong emphasis on hands-on learning through a multitude of exercises and demonstrations.

Students will be guided through a wide variety of in-class labs specifically designed to offer practical solutions to common problems that address real-world production needs. Topics covered include: multi-view apps, design-patterns, data-persistence, core data, web-services, JSON and XML parsing, maps and location services, working with images and animations, and handling gestures. An in-depth look at the Xcode 8 IDE and its many features and tools will also be included.

Course Duration: 5 days
