Obi Cloth 4.1 Crash on Apple A12 devices. - alkis - 06-06-2019
We have run into an issue where Obi Cloth reliably crashes on Apple A12 based devices. I have created a minimal repro project based on the Runtime Cloth example of the distribution. The issue happens on both 4.0 and 4.1. The attached project crashes on A12 devices, such as the iPhone XS and XR, but not on any other devices we have tested on, including A9, A10 and A11 devices. We are building using Unity 2018.4.1f1 and Xcode 10.2.1 (10E1001). The devices are running iOS 12.2.
There are multiple different stack traces for the crashes, I have attached some.
The issue was unfortunately discovered in the last minute and blocked us from making a release using Obi, we will have to temporarily strip the assets using it until a solution can be found.
To repro with the project attached, unzip into a base distribution of 4.1 (or 4.0 for that matter, same result), build, run on a A12 device and tap to spawn a sack.

Hi there,
Thanks for reporting this!. We've had similar reports from other users but never got to reproduce crashes on iOS. However we only have A5, A7, A10 and A11 devices to test. So this might explain why we were never able to reproduce anything.
Will try to get an A12 chip to test asap.
kind regards,

If you need any more information (debug output from any debug version of Oni or what not), drop us a line! :-)

Hi, we have the same problem. All is working fine but on the newest Apple devices (Iphone XR, Iphone 11 and 11 pro) our app crash with an access denied exception on Oni. We are using obi 4.1. Any news about this issue?
