Black screen on iOS devices

Question

I'm using Easy AR for augmented reality and it is working on android devices but not on iOS devices. I get black screen on iPhones and iPads as soon as I open my Easy AR scene.

 I'm using Easy AR 2.0 SDK with Unity 2017.3, I also have the OneSignal SDK in m project, could that be causing this problem?

I read that we need to merge all the AppControllers in the project, I'm not sure on how to proceed with this, can anyone help?

Comments

this assumes that I've also included movie texture as well, but I'm not using movie texture in the project. Will this still solve the issue ?

Is there a detailed log information?

No , I don't have logs . I tried building it without OneSignal SDK in the project and I the Camera opened but as soon as I scanned the card, the app crashed.

Hi did anyone solve this?

Thanks
