[NSNull __detox_sync_untrackAnimation]: unrecognized selector sent to instance

[Kudo]

hi there!

we came across a crash issue from detox and in the call https://github.com/wix/DetoxSync/blob/962b297bf77f4c98decac40a2daa7b90394abe54/DetoxSync/DetoxSync/Spies/CAAnimation%2BDTXSpy.m#L30

this function is called after [UIViewPropertyAnimator stopAnimation:] but ios passing NSNull as the (CAAnimation *)anim parameter. does it make sense to check if the anim is NSNull like this?

the crash stacktrace is like this:

@Kudo thanks for the report and suggestion. This does seem like a DetoxSync issue!
Could you perhaps provide more details regarding the use case where this happens? Which navigation stack (and which navigation project) and what animation is in effect, among other things.

hi @d4vidi, this issue happens from detox testing with the code where we create a UIViewPropertyAnimator and stop it in destructor. you can search the animator property in the code above.

thanks for looking into this. let me know if you need any other information.
