[iOS] ARKit reorders the XR Reference Image Library when built on iOS

Package: ARKit

-

How to reproduce:
1. Open the user-supplied project
2. Build the "SampleScene" Scene for iOS and deploy it
3. Enter Play Mode in the Editor and compare the Game view with the Player's output

Expected result: the Player's output is the same as the Game view in the Editor (Reference Images are outputted in order)
Actual result: the Reference Image order is reversed in iOS

Reproducible with: ARKit 3.1.0-preview.4, 3.0.1 (2019.3.0f6, 2020.1.0a25)
Could not test with: ARKit 2.0.1, 2.1.1, 2.1.2, 3.0.0-preview.1, 3.0.0-preview.4 due to package errors

Reproduces on:
VLNQA00160 iPhone 6s iOS 13.3.1

  1. Resolution Note:

    Unfortunately, the reference image library is internally stored in an unsorted set on the Xcode side so we can't guarantee the edit-time ordering will match the runtime ordering. Please use the GUID and string identifiers rather than depending on the index of the list in the editor.
