Troubleshooting UITableView Swipe Actions in iOS 14.4 Simulator

If you are developing an iOS application that requires swipe actions on a UITableView, you might encounter issues when testing it on the iOS 14.4 simulator. It's frustrating when your code works perfectly on a physical device or a different iOS version, only to fail in the specific environment. This guide will help you address the issue where the trailingSwipeActionsConfigurationForRowAt method is not triggering swipe actions as expected in the iOS 14.4 simulator.

Understanding the Issue

In your implementation, you used the following code to set up swipe actions for your table view rows:

While this code functions correctly in the iOS 16.1 environment and on physical devices, it fails on the iOS 14.4 simulator. The good news is that there’s a solution!

The Solution: Implementing the canEditRowAt Method

To get the swipe actions to work on iOS 14.4, you need to ensure that your UITableViewDataSource allows for editing the rows. You can do this by implementing the following method in your data source:

Breakdown of the Solution:

Implement the Method: Add the canEditRowAt method in your UITableViewDataSource. This method informs the table view whether a specific row can be edited (which includes swipe actions).

Return True: Make sure to return true for any rows that should have swipe actions. This way, the table view knows it can present the configurable actions you have defined.

Testing: After implementing the above method, run your app again on the iOS 14.4 simulator to see if the swipe actions now appear.

Conclusion

Implementing canEditRowAt is a crucial step for enabling swipe actions in a UITableView on older iOS versions, specifically iOS 14.4. By ensuring this method is in place, you can ensure that your swipe actions function properly across different environments, avoiding any discrepancies between the simulator and physical devices.

By following this guide, you can successfully troubleshoot your UITableView swipe actions and enhance the overall user experience of your app! If you have any questions or comments about this implementation, feel free to leave them below!
