Issue is Plugin.SharedTransitions.Platforms.iOS.ViewExtensions Line 91 NSKeyedUnarchiver.UnarchiveObject throwing this error.
ummm.... i tought i fixed that. Are you animating a custom view or something generated by a plugin ?
I have encountered this same issue and it should be reproducible in this repo: https://github.com/sthewissen/coffeeffee
thank you! i stopped the release of the new version (compatible with androidx) to fix this issue. it could be in the next couple of days.
Maybe i'm tryuing to optimize the animation too much and need to stop do duplicating views when i can and just take a snapshot, but then i cant animate borders, ecc
ah found it! it has something to do with CG. And when i copy the object it has to be recreated but the Unarchiver needs a constructor wich get an IntPtr as param but the FormsUIIMageView in Xf.Core doesnt have that. Soooo, if this plugin was in core i will be able to fix this with just 1 line of code :( For now i have to do something more creative :)
Awesome!
