In this challenge we will build a complete app from scratch on our own.
This time our goal is to create a habit tracker app for people who want to keep track of how much they do certain things.
We will look at customizing the Navigation Bar view in SwiftUI navigation. In this way, we will be able to place the toolbar buttons in exact positions and edit the navigation title.
In this section we will build our iExpense application using @Observable, sheet(), Codable, UserDefaults.
@Observable : Monitors a class for changes and refreshes all affected views.
