Adding an Edit Page

The next step to making a fully functional crud app is adding edit functionality to the. I will need to allow the user to open an edit/details page when a specific review is tapped.

step 1: - add the Show Detail segue

In XCode, this is done using control - drag from the MealTableViewCell -> NewMeal view controller scene

step 2: - pass meal thru segue

in the MealTableViewController.Prepare() method, add conditional logic that checks which segue is clicked using segue.identifier property. If a review was selected, then pass that data into the segue

step 3: - populate edit form

In MealViewController, you can check if a meal object was passed from the segue. If one was, assign the meal properties to the form fields on the edit page.

step 4: - redirect and update the review

Once the user saves their edits, a meal object will be passed back to the unwindToMealList method in MealTableViewController. I then update the meal object and reload that row.
