SwiftUI-Using-Core-Data

Basic concept of using SwiftUI with Core Data via FetchRequest property wrapper or NSFetchedResultsController

  • Developed in Xcode 11
  • This is a simple SwiftUI application that shows a list of entries to display whether the user went to the gym or not
  • The app displays 2 methods of fetching the entries from Core Data and displaying it on List
    • FetchRequest property wrapper which requires managedObjectContext as an environment variable set within the view
    • NSFetchedResultsController with a CurrentValueSubject
  • Presents a modal view via .sheet view modifier and using presentationModel @Environment variable to dismiss the view
