[Bug] ARKit ARWorldMap save and restore makes app crash #953

Closed wangyugod closed 2 years ago

wangyugod commented 2 years ago

Hi there, I have a function that saves and restores ARWorldMap in my App, my operation flow:

  1. open my app and scan around
  2. save ARWorldMap to ipad local storage
  3. load to restore ARWorldMap After repeat step 2 and 3 several times, my App crashed. I thought it was my code issue but cannot find any clue, actually my code is copied from ARFoundationSample. Then I downloaded official ARWorldMap Pesistent demo from https://developer.apple.com/documentation/arkit/data_management/saving_and_loading_world_data, repeat the operation as above, it also crashed. My iPad version is iPad Pro 15.3.1, my xcode version is 13.2.1, and the error log said dyld4 config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection.dylib blahblah, please check it from attachment. Any help is appreciated. error-min error

Update for more information, I enabled plane visualization for detected plane, when I save and load the ARWorldMap, the planes became denser and denser, and app became much slower.

If you are able to reproduce this with Apple's sample, then it isn't a Unity-related bug and it's unlikely they will be able to help. I recommend that you report this to Apple here:
