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:

1. Run the app on an iOS 15 device but works perfectly in iOS 17
2. Attempt to load a WebP image using SDWebImageSwiftUI.
3. 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
