    addNote.details = noteText.text!

    //Saving
    (UIApplication.shared.delegate as! AppDelegate).saveContext()

}

let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
var Notes: [Note] = []

func getData() {
    do {
        Notes = try context.fetch(Note.fetchRequest())
    } catch {
        print("Fetching Failed")
    }
}

override func viewWillAppear(_ animated: Bool) {
    getData()
}


override func viewDidLoad() {
    super.viewDidLoad()
    let MyIcon = UIImageView(image: UIImage(named: "037_Pen"))
    self.navigationItem.titleView = MyIcon

Dealing with data in iOS application

If you want to save your data inside application then you need to do something more inside your application for data saving purpose. This way you can save data inside application weather terminate application it will show your saved data and fetch again.

1.) For Short Date save can use UserDefaults

2.) By using SQLite

3.) By Using Coredata

4.) By Using Realm, For more details check Example.

You need to create database to save the text value every time as per your requirement.

You can create the database by using any one of the below :

  1. Core dataGet tutorial from here

  2. SQLite Get tutorial from here

Save your text data by using anyone these and then fetch the data and assign at the UI.
