Passing a Struct Array through a TableViewCell to Another ViewController

If you're diving into iOS development with Swift, you might encounter situations where you need to share data between different parts of your app. One common scenario is passing a Struct array from a TableViewCell to another ViewController. This can seem a bit tricky if you are new to Swift, but with a few clear steps, you can achieve it seamlessly.

Understanding the Problem

When you tap on a TableViewCell, you generally want to display detailed information about that item in a new view. In this case, the data we are dealing with is not just a single piece but rather a Struct Array. By structuring your data well, you can facilitate efficient navigation and data sharing throughout your app.

Solution Breakdown

Let’s go through the steps necessary to pass a Struct Array from a TableViewCell to another ViewController.

Step 1: Create a Model Struct

First, ensure that you have a model struct which will hold the data you need to pass around. This should represent the items being displayed in your TableView.

Step 2: Define a Variable in Your Destination ViewController

Next, in the view controller to which you're navigating, create a variable to hold the selected data. Instead of creating an array, you can create an optional struct object.

This variable will store the specific instance of the Model you want to pass over when a cell is tapped.

Step 3: Implement didSelectRowAt Method

In your TableViewController, you need to set up the didSelectRowAt method. This is triggered when a user taps on a cell. Here’s how you can implement it:

What Happens Here?

Instantiate your destination View Controller: You create an instance of the Comment view controller.

Navigate: Finally, you push this new view controller onto the navigation stack, allowing the user to see the data they selected.

Conclusion

Passing a Struct array from a TableViewCell to another ViewController can greatly enhance your app’s functionality and improve user experience. By following the steps outlined above, you can set up an efficient method for sharing data throughout your iOS app.
