self.showAnimatedGradientSkeleton(usingGradient: gradient, animation: animation, transition: .crossDissolve(0.25)) Method.
I have a similar issue. Using SkeletonView 1.8.7 makes a collection view within a collection view cell (therefore nested) unresponsive (no horizontal scrolling or taps recognized), although the SkeletonView is used in a different view controller in a different tab. 🤷♀️
Ok, we need to investigate deeper
The only thing I meanwhile discovered was that the call to swizzleLayoutSubviews() disables the user interaction in my cell...without it, as far as I can see now, everything in our setup still works. Animated as well as non-animated.
After some more investigation and considering reworking my views I discovered that I was adding the nested collectionView to the cell view instead of the contentView of the cell, which is not supposed to work at all, but does until the swizzled layoutSubviews of SkeletonView changes something. Sorry for the fuzz... :)
