Hello!
I am in some desperate need for help… I am on Windows 10 (64 bit) and, basically, whenever I try to build my project for iOS, it fails saying it was unable to find the file “VuforiaPluginLoader.mm”.
This only happens when I enable VR using the Vuforia SDK for iOS - AR only works just fine (and so does VR on Android).
I tried reimporting Vuforia and even upgraded Unity to the latest patch (2017.3.0p4), but the issue persists. Building one of the example projects for Vuforia yielded the same result.
Here’s the full stacktrace
IOException: Failed to Copy File / Directory from 'C:/Program Files/Unity/Editor/Unity.exe\..\PlaybackEngines\VuforiaSupport\iOS/VuforiaPluginLoader.mm' to 'D:/Unity Projects/Builds/iOS_VR\Classes/VuforiaPluginLoader.mm'.

The file in question exists in my PC, but it seems Unity is somehow trying to find it inside the executable? Is there any way around this? Can I manually add the needed files and link them or something?
