iOS 15 Image Compression Leading to Unexpected Quality Loss in UIImage
I'm sure I'm missing something obvious here, but I'm working on a personal project and I'm relatively new to this, so bear with me. I'm working with an scenario with image compression in my iOS 15 app where the quality of the images degrades significantly more than expected when using the `UIImageJPEGRepresentation` method. I've tried adjusting the compression quality parameter, but the results are still unsatisfactory. Here's my current implementation: ```swift if let imageData = UIImageJPEGRepresentation(originalImage, 0.5) { // Save or upload imageData } else { print("Failed to compress image.") } ``` When I set the compression quality to 0.5, I expected a moderate reduction in quality, but the images appear almost pixelated, especially on the iPhone 13. I also verified that the `originalImage` is a high-resolution photo. I've looked at the image size after compression, and while it reduces, the quality seems to drop disproportionately. I tried switching to `UIImagePNGRepresentation`, but that just keeps the original quality, leading to larger file sizes that aren't suitable for my upload constraints. Also, I attempted using the `AVAssetExportSession` for video frame extraction, and I saw the same quality degradation scenario. Is this a known scenario with iOS 15, or am I missing something in the configuration? What are the best practices for image compression to avoid such quality loss? Any insights or alternative methods would be greatly appreciated! What am I doing wrong? This is part of a larger application I'm building. How would you solve this? This issue appeared after updating to Swift 3.10.
