The cell reuse strategy in Swift is a memory optimization technique that helps reduce the amount of memory used by an app when displaying large collections of items, such as lists or grids. This strategy reuses cells that are no longer needed instead of creating new cells, which can help improve the app's performance.

However, if the cell reuse strategy is not implemented correctly, it can lead to various display issues, including incorrect images being displayed or images not being displayed at all. This can happen if a reused cell contains old data and does not get updated with the new data when it's reused.

To fix this issue, you can try resetting the cell's image before reusing it or using a unique identifier for each cell to ensure that the correct data is displayed in each cell. You can also try using a cache to store previously loaded images to reduce the number of times the app needs to fetch them from the network.
