Inserting Data Into the Context

This video was last updated on Jul 19 2022

Now that you have a RocketLaunch class you can use learn how to populate it and save data to the persistent store.


Heads up... You've reached locked video content where the transcript will be shown as obfuscated text.

You can unlock the rest of this video course, and our entire catalogue of books and videos, with a Professional subscription.

In the last video you created a managed object subclass for the RocketLaunch entity. Now you can use this class to create instances of a RocketLaunch for users to save. If you build and run the app, you’ll see a new rocket launch button at the bottom of the screen. When you tap on that you’re presented with a modal view to enter details about the rocket launch.

let persistenceController = PersistenceController.shared
	.environment(\.managedObjectContext, persistenceController.container.viewContext)
import CoreData
@Environment(\.managedObjectContext) var viewContext
let launch = RocketLaunch(context: self.viewContext) =
launch.notes = self.notes
launch.launchDate = self.launchDate
launch.isViewed = self.isViewed
launch.launchpad = self.launchpad
do {
catch {
  let nserror = error as NSError
  fatalError("Unresolved error \(nserror), \(nserror.userInfo)")
  static func createWith(
    name: String,
    notes: String,
    launchDate: Date,
    isViewed: Bool,
    launchpad: String,
    using managedObjectContext: NSManagedObjectContext
  ) {}
	notes: self.notes,
	launchDate: self.launchDate,
	isViewed: false,
	launchpad: self.launchpad,
  using: self.viewContext)
A really cool launch
My back yard
I really hope this takes off!
