I have same the issue.

I use Unity 2017 LTS for a while.

So Please, fix the bug on both Unity 2017 LTS and Unity 2018.

Same problem here with Unity 2018.1.8 and Vuforia 7.2.24...

Any update on this, Vuforia Support?.

We are experiencing the same error in Unity 2017.4.8 and Vuforia 7.0.57

Same problem here with:

Unity 1018.1.3f1

Vuforia SDK version 7.1.35

Tried different ways:

• Normal build
• Debug Build
• Metal enabled
• Metal Disabled

but no luck... on XCode the "crash point" is at:

SurfaceUtilities_OnSurfaceChanged_m3622836527(NULL /*static, unused*/, L_14, L_15, /*hidden argument*/NULL);

on:

Classes/Native/Bulk_Vuforia.UnityExtensions_1.cpp

function:

Vuforia.MonoCameraConfiguration::CheckForSurfaceChanges()

and on console:

If anybody has a workaround for this crash... it will save my life!

Hello waldeist,

Which iOS devices and iOS versions do you see this on? Can you reproduce it in the samples?

Thanks,
