How to best use Core Data with SwiftUI - MVVM - Unit test and working with the preview

In this tutorial, I am discussing ways on how to use Core Data with SwiftUI 2.0. I will use the template generated by Xcode for Core Data. In order to get a correct updating of the UI it is very important to consider Core Data entities as classes. In SwiftUI we can use the @FetchRequest property wrapper. I will try to use MVVM design pattern in a different way. The goal is to write clean code and include unit test. 00:00 intro 02:16 What is MVVM? 05:05 Xcode template with Core data 20:27 using extensions for convenience initialisers 26:27 Core data entities can act like view models 34:02 optional attributes and syntactic sugar 39:11 core data working with the preview 47:14 unit tests 54:30 save content with ScenePhase going into background 01:00:06 wrap up Watch more MVVM SwiftUI tutorial:    • How to use MVVM in iOS - State Management ...   Stanford course SwiftUI and Core Data Part 1:    • Lecture 11: Picker   Stanford course SwiftUI and Core Data Part 2:    • Lecture 12: Core Data   If you liked what you learned and you want to see more, check out one of my courses! 👨‍💻 my SwiftUI course https://school.swiftyplace.com/course... 👨‍💻 my Core Data and SwiftUI course https://school.swiftyplace.com/course... 👩🏻‍💻 Combine course https://school.swiftyplace.com/course... #SwiftUI #CoreData
