SwiftData Essential Training

Course details

SwiftData allows you to handle persistent data quickly and easily in your applications. In this course, instructor Steven Lipton provides a comprehensive introduction on how to leverage this powerful framework built for Swift and SwiftUI.

Learn how to build models and apply those models in SwiftUI code, testing out your skills in the exercise challenges at the end of each section as you go. Steven covers the basics of filtering and sorting, common data issues, child tables, and attributes and settings. Along the way, you’ll find out how to create, customize, and work with model containers and migrate data like a pro.
