This workshop and series of exercises to build 3 SwiftUI iOS applications will help you improve your development skills and introduce you to some best practices.

This workshop is not intended for absolute beginners, but the content is arranged in such a way that if your experience is limited, you will be able to cut and paste code from the provided documentation without getting left behind.

You will have access to the all of the completed applications and documentation for your own personal or instructional use after the workshop is completed.

In addition, the documentation provides links to several supplementary videos on several of the topics covered.

This is a very optimistic agenda based on the time available so if we do not complete it, hopefully this documentation and supporting videos will help you work through it on your own.
