Drawing App - Part 2 - Save and Retrieve Data Locally Using FileManager and UserDefaults in SwiftUI
In this SwiftUI tutorial, I am saving the user drawing to the file system with the FileManager. I will modify the model to conform to the Codable protocol. The tricky part is saving Colors.
In the second part, I want to restore the settings for a color picker and slider. This allows to keep all the application state for the next time the user launches my application 🥳. I am saving the values of a slider and color picker to UserDefaults.
