After having gone through and deleted all my sprites to open the project in Unity 2020.2b12 I got it to export an xcode project on for the iOS platform. After running the game for about 20seconds and into the main menu (where I use burst compiled code) it immediately crashes with the strack trace
Unable to find internal function
‘Unity.Burst.LowLevel.BurstCompilerServices::GetOrCreateSharedMemory’ Unity.JobsLowLevel.Unsafe.JobsUtility.CreateJobReflectionDataType(Type, Object, Object, Object) UnityEngine.Jobs.TransformParallelForLoopStruct’1:Initialize() UnityEngine.Jobs.IJobParallelForTransformExtension:Schedule(ObjectMoveJob,TransformAccessArray, JobHandle)
So my understanding is that it crashes immediately when I create a Job which deals with some transforms in a for loop.
