    Hi,

    I upgraded to 2018.2 last night an now I'm getting console warnings that runtime package files are conflicting with cache packages in the library:

    GUID [dbca4b5d18c5b4a59ad11c981347242d] for asset 'Packages/com.unity.xr.arkit/Runtime/iOS/UnityARKit.a' conflicts with:
    '/Users/matt/Library/Unity/cache/packages/packages.unity.com/com.unity.xr.arkit@1.0.0-preview.12/Runtime/iOS/UnityARKit.a' (current owner)
    We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.

    Also getting warnings like this in the console when running in editor:

    Found 2 XRSessionSubsystemDescriptors. Using "ARCore-Session"
    UnityEngine.XR.ARFoundation.ARCameraBackground:OnEnable()

    Found 2 XRCameraSubsystemDescriptors. Using "ARCore-Camera"
    UnityEngine.XR.ARFoundation.ARCameraBackground:OnEnable()

    ...

    Any thoughts?

    I am also getting 3 GUID warnings in the console after updating to Unity 2018.2; these warnings pop up every time you return focus to the Unity Editor. Two are related to ARKit and one is related to ARCore.

    These warnings act the same way in the current AR Foundation Sample project as well.

    I can't find a way to clear this warnings.

    Yep, the GUID warnings are known. They should be harmless, though. Are they causing any other issue besides unwanted spam?

    Not that I have witnessed. They are simply annoying. :)

    I don't know if they're related but I'm getting those warnings, everything in my project is pink now (Updated this morning from 2018.1.x)

    I'm also getting a bunch of errors similar to this:
    Shader error in 'Deferred.compute': undeclared identifier 'EvalShadow_SampleClosestDistance_Punctual' at kernel Deferred_Indirect_Fptl_Variant20 at LightLoop/Shadow.hlsl(121) (on d3d11)
