UICollectionViewCell: Change Border Color on Cell Select

Customizing the appearance of UICollectionViewCell is a common task in iOS development, especially when providing visual feedback for user interactions. One popular customization is changing the border color of a cell when it is selected. This guide will guide you through the process of achieving this effect using Swift.

Step-by-Step Guide

Create a Custom UICollectionViewCell

First, you need to create a custom UICollectionViewCell subclass. This subclass will handle the appearance changes when the cell is selected.

Register the Custom Cell

In your view controller, register the custom cell class with the UICollectionView. This is typically done in the viewDidLoad method.

Update UICollectionViewDelegate Methods

Ensure that the collectionView(_:didSelectItemAt:) and collectionView(_:didDeselectItemAt:) methods are implemented. These methods update the isSelected property of the cell, triggering the border color change.

Conclusion

With these steps, you have successfully implemented a custom UICollectionViewCell that changes its border color when selected. This small but effective visual cue can significantly enhance user experience by providing clear feedback during interactions.

Feel free to customize the border color and other visual properties to match your application's design language. Happy coding!
