SDWebImage
The images in WebP format are not loading or displaying correctly on iOS 15, but they work fine on iOS 17. I haven’t tested on iOS 16 yet.
Steps to Reproduce:
- Run the app on an iOS 15 device but works perfectly in iOS 17
- Attempt to load a WebP image using SDWebImageSwiftUI.
- Observe that the image does not display as expected.
Expected Behavior: WebP images should load and display correctly on iOS 15, similar to how they work on iOS 17.
Actual Behavior: The WebP images are not loading or displaying correctly on iOS 15.
Additional Information:
- SDWebImageSwiftUI version: 2.2.7
- iOS version: 15.x
- WebP images are loading fine on iOS 17.
- I have not tested on iOS 16 yet.
if let url = URL(string: "https://www.gstatic.com/webp/gallery/1.webp") {
WebImage(url:url) .resizable() .placeholder(Image("vendor_background_placeholder")) .onSuccess { image, data, cacheType in print("Image successfully loaded") } .onFailure(perform: { error in print("Image loading failed (error.localizedDescription)") })
}
in ios 17 I am seeing logs "Image loaded successfully" but in ios 15 neither success nor failure log is displayed in console
pod 'SDWebImageSwiftUI'
Please let me know if there are any additional steps I should take or if there are any workarounds available.
Thank you!
Anything related to Apple's own decoder (ImageIO framwork), maybe you should ask Apple to fix :)
If not, you can have a try with our custom decoder using libwebp (open-sourced)

Apple's system decoder may have different behavior on different firmware OS version, but our third-party based decoder always has the same behavior across any firmware version
