Hi,

I believe you need to enable the Metal Editor Support option.

In unity under Build Settings -> Player Settings -> Player -> you have the option "Metal Editor Support". Please enable that and give a try.

Thank you.

Vuforia Engine Support

It's enabled. Moreover I can force Vuforia to use Metal, using initQCARiOS native method call. And it selects Metal (based on what I see in logs), but after that it says "vuforia engine cannot be started before it is initialized ios" and if I'll use VuforiaRuntime initialization method - it results in conflict. What I need to call in addition to initQCARiOS? 

I had exactly the same problem. We were forced to change the framework to another, although we wanted to use Vuforia. So far, we have not found a solution to this problem, Vuforia behaves very strangely and the selected Vuforia settings, when exporting a Unity project for integration into native applications, behave very strangely and looks corrupted.

• Can some one from Vuforia support explain, how to manually initialize Vuforia in native project, when it was exported from unity as library? Which native methods calls should I use, when It was exported as part of unity project? 

Hi,

This should be achievable through the build settings from unity. Under Player->Other Settings -> Auto Graphics API// Uncheck the box. After that you will have a drop down menu with the Graphics API. Remove OpenGles2 version from there and try to build it again.

Thank you.

After that it still tries to select opengles 2.0

Hi,

Coming back to your first post, I've noticed that exporting the project from Unity directly to iOS works as expected and Metal is being used. The issue happens only when you include the unity exported project in the native project.

What is the native project? is it empty? are you just opening the unity project with Xcode?

Thank you.
