If build the app as hybrid with xr support set on None and Cardboard, it starts, but when I switch to Cardboard the app freezes and I can't do anything and Xcode displays this log

UnityEngine.DebugLogHandler:LogFormat(LogType, Object, String, Object[])
UnityEngine.Logger:Log(LogType, Object)

It is also happening if I build the HelloVR scene

Please anybody help me :)

This happens on my Mirage solo as well. The projects work's fine in unity 2018.3.10f, (i bet all versions of 2018.3) But in 2019.1 the screen's just black.

I have the same problem on my iPhone 5S with the new unity 2018.4 LTS. Hope we can find a solution to fix this.

UPDATE - SOLVED (at least for me): The issue was because Vulcan was enabled under Other Settings -> Graphics APIs

I removed Vulcan from the list and now everything's fine.

It's not just iOS.

This issue is also happening on my Galaxy S9 in Android, even with the VideoDemo sample scene.

Again, not even the splash screen appears. I do know the app is running because I get the X, the settings gear and the alignment mark at the bottom. Everything else is just black.

This is happening with my Pixel 3 and Unity 2019.1. Not just iOS, someone should change the title.
