Issue Description and Steps

the SDWebImageWebPCoder is 0.2.3 - 0.2.5, in iOS 12.x or lower version, can not show webp image, but the strange thing: when I debug app to those devices using xcode(11/10), it can show webp correctly. and close debug, start-up app directly, it cannot show webp again.
btw, when I use 5.1.0 and webpcoder 0.2.3, everything is fine.

@wanght Can our demo reproduce this issue ? Use the SDWebImage repo's demo to have a try ?

cd SDWebImage
pod install
open SDWebImage.xcworkspace

[dreampiggy]

Using iPhone Simulator running iOS 12 (without debugger, follows what you says and close debug, start-up app directly, it cannot show webp again.), can not reproduce this issue.

Is this issue only re-producable on iOS 12 real device ? (I don't have one, so could you please use our demo and run iOS 12 real device to have a check ?)

I tried demo project, it works on 11.x device fine, I can't find the reason, the image display code has no change for a long term, the only changes on my project is I changed BITCODE compile to non-BITECODE

the only changes on my project is I changed BITCODE compile to non-BITECODE

Does this means, there are something in-compatible issue of libwebp with Bitcode ? I can have a try later.

[wanght]

Maybe with non-bitcode, because I used BITCODE compile before, and everything works fine. But recently I use a sxxt library that can't compile with bitcode. so I change my project to non-bitcode mode

[wanght]

Sorry for mistakes, tried on iOS13 is fine, but on iOS12 or lower, it still not fixed yet.

[dreampiggy]

Still a strange issue, that I can not reproduce in local environment on iOS 12.

If you can, attach a demo project, that you can ensure this issue exist, or we can not identify the issue and provide the fix.

Did you have conditional firmware check code to add the SDImageWebPCoder like this ?

if (@available(iOS 13, *)) {
    [SDImageCodersManager.sharedManager addCoder:SDImageWebPCoder.sharedCoder];
}

[wanght]

其实没有做任何版本的检查，之前在所有iOS平台都是没有问题的，后来因为加了一个不支持bitcode模式的三方库，被迫整个工程都采用非bitcode编译，之后就只有iOS13才能显示webp了，显示相关代码一直都没有动过

I upgrade to 5.6.1 and SDWebImageWebPCoder to 0.5.0, tested on SE with iOS 11.2.5, problem fixed, thx!
