Had an interesting bug crop up here. On the lines where Jessy changes the ContentView() call to ContentView( taskScore: TaskStore() ) he deletes the TaskStore placeholder and retypes the same code. I neglected to delete the placeholder and just added the parenthesis. This creates a bug in the code whose “fix” is to delete the parenthesis but what really needs to happen is to delete the TaskStore placeholder and retype it. ---

In my opinion the second app tutorial is much too advanced. There should be a tutorial in-between the first and the second app that will reinforce theory from the programming essentials video. ---

Starting a new app project now does not even include the scene delegate file - so this was a bit confusing. Ended up applying the same logic to `TaskListApp.swift` file. ---
