Reply To: [NC2] AoT iOS Jit Error on Startup

That solves some of the issues we’re seeing, but not all. We’re still seeing the error I mentioned in my most recent post.

We’ve made some progress by modifying the Read and Write functions of fsMetaProperty to intercept Rects, Keyframes, and AnimationCurves and explicitly getting and setting the appropriate properties. This seems to break some functionality, and I’m not sure why. I’m also not sure why Read is getting called at runtime, since that seems to be a method related only to serialization.

Matt, I’d be interested for our purposes to see if these errors are PS4-specific. Can you try Gavalakis’s solution and see if you’re also getting the error I have above?

Our version of the fsMetaProperty methods follows. I will update if we figure out what else is breaking.
