ios sdwebimage memory-management swift

I've hit a wall trying to I'm migrating some code and I've looked through the documentation and I'm still confused about I've searched everywhere and can't find a clear answer. I'm working on a personal project and Building an application that relies heavily on dynamic images, I've integrated the SDWebImage library to handle image loading and caching. However, during testing, I've noticed a significant memory spike when scrolling through a list of images in a UICollectionView. Despite implementing the recommended caching strategies, the app seems to consume more memory than expected, especially on older devices. Here's a snippet of how I'm currently setting up the image loading: ```swift import SDWebImage class ImageCell: UICollectionViewCell { @IBOutlet weak var imageView: UIImageView! func configure(with url: URL) { imageView.sd_setImage(with: url, placeholderImage: UIImage(named: "placeholder")) } } ``` The UICollectionView has about 50 images, and I'm setting the `imageView` using `sd_setImage` directly. To mitigate this, I have enabled `SDImageCache.shared.config.maxMemoryCost` and set the `maxMemoryCountLimit` to 50, but it doesn't seem to make a difference. The app crashes with an `EXC_RESOURCE` error after scrolling for a while, indicating that memory usage is exceeding the limit. I tried profiling the memory usage using Instruments, and it seems like cached images are not being released even when they are no longer displayed. I'm unsure about the best practices to manage memory effectively in this scenario. Any suggestions on optimizing the image caching or troubleshooting potential memory leaks would be greatly appreciated. I’d also like to know if there are specific configurations in SDWebImage that might help with memory management. Additionally, I am using Swift 5 and targeting iOS 17.0. Any help on this would greatly assist in ensuring a smoother experience for users as I prepare for our MVP launch. My development environment is Windows. Any help would be greatly appreciated! My development environment is Ubuntu. Has anyone else encountered this? I've been using Swift for about a year now. Thanks for your help in advance! I'd be grateful for any help. I recently upgraded to Swift 3.9. Thanks, I really appreciate it! Cheers for any assistance!
