Same issue here on 0.63.3 with iOS14.

I did a bit of digging into the ios animated image code and found that if I changed this:

      // A loop count of 1 means it should repeat twice, 2 means, thrice, etc.
      if (loopCount != 0) {
        loopCount++;
      }

to this:

      if(@available(iOS 14, *)) {
      } else {
      // A loop count of 1 means it should repeat twice, 2 means, thrice, etc.
        if (loopCount != 0) {
          loopCount++;
        }
      }

then my animated gif renders only once on iOS 14 and still renders only once (as it always has) on iOS 13.7 as well. Maybe something changed with the way that gifLoopCount is calculated in iOS 14?

FWIW - this is the only thread I could find on this, but I was having the same issue with a non-looping gif rendering twice in a web project (not React or React Native). It was happening in both Safari and Chrome on my iOS 14 device until I updated to iOS 14.2 last night, and that resolved the issue for me.

can you explain how this line if(@available(iOS 14, *)) works?

loopCount is not increased on iOS 14 or higher.

changing the above code does not work on my project, still animating twice in ios 14.4,
attaching the gif and the video how it behaves on the app

are you sure that modal is gif?

and have you tried to rebuild your app after you change the module?

[aaron0215]

Any update on this issue? Or any official fix is done?

[noamyagil]

[cojoclaudiu]
