Entities not rendering on mobile

I'm using the Standard Shader (set to Fade).
In the Editor, all of my entities are working fine.
However, when I build to Android (or iOS), none of my Entities are being rendered.

In-Editor: https://gyazo.com/bd72ebddacf1f4b5860de5de669e84f5
In-Build: https://gyazo.com/5b6c3e721464356b482359c5894dde4b

Checking adb-Logcat I can see that my bootstrap is running fine, and my Entities are indeed being created.
I am getting a few errors with regards to UnityEngine.Jobs though:

The logs first made me think that the problem wasn't the rendering, but the positioning of the Entities.
However, even if I set my camera to look at 0,0,0, and remove all positioning-code, the entities still don't show up.
(The same errors show up in Logcat, even though I removed all SetComponentData-code for Position & Rotation, and completely commented out my positioningjob)

In-Build (background set to skybox, no other changes): https://gyazo.com/9a8ffe67651df013f46f8b765c3dc832

As the errors show up even without any of my own code; Is this a bug within Unity's code?

Edit: Running on Unity 2018.2.15f1 with:

Anyone?

 

So... after a LOT of headaches & tests, I figured it out.
USING IL2CPP AS SCRIPTING BACKEND BREAKS UNITY.TRANSFORMS
setting it to Mono instead fixes it.

 

@FrankvHoof I had the same problem. Take a look here:
https://forum.unity.com/threads/meshinstancerenderer-not-rendering-on-ios.591703/#post-3952090

 

Found this too on 2018.3.

 

I'm still seeing this issue on 2019.1.3f1 with Entities preview.33
It seems IL2CPP for iOS is stripping out native code which is referenced by C# that wasn't stripped?

 

You can add a link.xml to prevent assemblies from getting stripped.. You could do it very fine-grained, but if you're willing to sacrifice a little in build-size you can prevent entire assemblies from being stripped.
https://docs.unity3d.com/Manual/IL2CPP-BytecodeStripping.html

 

This only allows you to specify what Managed assembly to prevent from being stripped. The issue here is that Native functions are being stripped, which the managed code references.

 

UnityEngine.Jobs is a managed assembly.

 

Yes, and its not being stripped. The Native code it references is.

 

Which native code?

Edit: Do you mean the UnityEngine.Jobs-Code? That's being stripped because it's never called (because the package-code which calls it is also stripped)
