This is a simple, iOS project build in Swift Playgrounds 4, this app build in SwiftUI. Also, this app show how to implement CoreData in Swift Playgrounds 4. The idea of this app is about task todo list that can track all your tasks, and categorized their properties in three different properties (High, Medium, Low). It presists task in CoreData.
NOTE: I recommend using latest version of Xcode, if you're going to run this app on macOS.
