    Hi guys,

    I'm trying to get a simple sample of ARFoundation running on our iPhone but can't seem to get it working. I've followed this example with just a cube and the bare ARFoundation objects needed:


    After running on the iPhone the screen stays black and after a few seconds the app crashes. On Android all this works fine.

    Here is my current setup:
    -- Unity 2019.2.9f1
    -- MacOS Catalina 10.15
    -- XCode 11.1
    -- iPhone Xr
    -- ARFoundation/ARKit XR Plugin 2.0.2 (and 3.0 preview 3 and 4).

    I've also tried to run the arfoundation-samples from GitHub and that also failed, with a pink background (shader issues I guess) and then a crash.

    Here is the output when I run it attached to my iPhone:

    And finally, this is where it crashes:

    If anyone has a clue what's going on I'd appreciate some info. Running out of ideas here, aside from maybe some bad hardware or the versions of the AR pieces and iOS don't work together.

    Thanks!

    I have the same issue. Works on Android and not iOS. For some reason the shaders do not compile when building for iOS.

    I am having the exact same problem. Android build is fine but for iOS I am getting:

    If I change color space to Linear from Gamma it works fine.

    Had the same issue and this did not work for me. We do have a lot of custom shaders, so that might be the issue at hand.

    It's an issue with the shader compiler on Catalina, MushDevStudio already found the bug on the Unity Issue Tracker:
    https://issuetracker.unity3d.com/is...1.1412129407.1572251278-1740351432.1547632638

    I use the 2019.3 beta of Unity, which solved the issue for me, but I can imagine that might not be the best way for you. There are a couple of workarounds in the comments on the issue tracker. Or perhaps switching the color space works for you as well.

    Thanks TalespinJoe - I have now updated to 2019.2.11f1 and now it is working perfect with Gamma color space.

    I had the same problem, after trying a few tests, disable and enabling the graphics options and installing and uninstalling software versions for iOS, I got a solution without the need to switch the Color Space rending to Linear. Leaving the default settings (Gamma color space). I notice that when I create a new project, the "Auto Graphics API" checkbox is enabled, so after disabling this I resolve my issue of the pink screen.

    TL;DR
    Have you tried to disable the "Auto Graphics API" checkbox?

    Disabling "Auto Graphics API" had no effect for me.
    Does the iPhone model matter? I'm running an 8+.

    Edit:
    Using 2019.2 and disabling Auto Graphics API and changing Color Space to Linear finally worked. Still getting several errors in XCode, but at least I can continue development.

    Upgrading to 2019.3b and turning on Auto Graphics API and changing Color Space to Gamma also worked.

    Thanks @TolchinJ , your suggestion..."Upgrading to 2019.3b and turning on Auto Graphics API and changing Color Space to Gamma also worked." fixed the problem that I was having. I greatly appreciate your posting it!
