UITableViewCell, show delete button on swipe

How to Show Delete Button on Swipe in UITableViewCell 👀🔍

You're swiping away on your UITableViewCell like it's a Tinder profile, hoping to see that magical delete button appear. But alas, it's nowhere to be found! 😭 Don't worry, you're not alone in this struggle. Many developers have faced the same issue and I'm here to rescue you from the deletion dilemma. 🦸‍♀️

The Problem 😕

So, you're wondering why the delete button doesn't show up when you swipe on your UITableViewCell. You've tried everything, but the delete button is as elusive as a shiny Pokémon. 🚫🗑️ What could be wrong? Well, the root of the problem lies in the cell's editing mode.

The Solution 💡

To make that delete button appear, you need to put your UITableViewCell in editing mode. It's as simple as that! 🎉 Here's how you can do it:

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, 
               forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        // Delete operation logic here
    }
}

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

By implementing the tableView(_:commit:forRowAt:) method and returning true in the tableView(_:canEditRowAt:) method, you enable the editing mode for your UITableViewCell. This allows the delete button to finally make its grand entrance!

Example Code 🚀

To provide you with some context, let's look at a simple example. Imagine you're building a to-do list app and want to allow users to swipe and delete their completed tasks with ease. Here's how you can achieve that:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return tasks.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "TaskCell", for: indexPath)

    // Configure your cell

    return cell
}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, 
               forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        tasks.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .fade)
    }
}

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

In this example, we have a tasks array that holds our to-do items. When the user swipes on a cell and taps the delete button, we remove the corresponding task from the array and update the table view accordingly. ✅
