Is it just me who experiences the whole scene freezing in ARKit on iOS 12? It usually happens when you use the app for too long in a space that generates too dense point clo
Are you still having the problem? I faced a much worse problem today after upgrading to Xcode10 and iOS 12. I was so crushed when all my ARKit 1.5 projects faced freezing after the first frame was captured from the start.
I managed to solve it by changing project setting, the Deployment Target under General to 12.0. I restarted Xcode just to be sure. All my ARKit projects work now.
I hope this helps, if I find more issues with image recognition freezing on iOS 12 I will mark them here.
