Camera don't work on iOS device

By martinprot on Mon, 05/28/2018 - 15:53

Hello

When compiling the Image Target sample app on iOS, the main camera do not display anything (black screen). But If I choose the front camera, it's working.

- unlike other posts related to this problem, Image Target do not work either : no image is detected.

- I have exactly the same problem on a ground plane scene, but ARKit seems to detect the planes (the square reticule is moving)

- on Android devices, everything works fine.

- I correctly set the camera usage description in iOS settings, I kept

- here's my versions : Unity version is 2018.1.2f1 / Vuforia version is 7.1.34 / iPhone 7, iOS 11.3

Is it a known problem, or does it comes from my configuration ?

 

Many thanks.

for me the fix was to reinstall xCode 9.2 and copy the IOS11.3 Device support folder from xCode 9.3 over to 9.2

Oh!

Thanks @LHiller for pointing up the known issue.

Unfortunately reverting to Xcode 9.2 is not an option, because my only iOS device is iOS 11.3 and previous Xcode version just won't compile on this iOS.

@Vuforia team, when can we expect a fix for this issue?

We have not seen the black screen issue with Vuforia 7.1.34 on any devices. Can you confirm you are seeing this in the sample projects? Can you also share a screenshot of your Vuforia Configuration?

I've tested this using the same setup as you (iOS 11.3, iPhone 7, Unity 2018.1.2f1, and Vuforia 7.1.34) and am not seeing a black screen. Can you check what I asked in my previous post and also confirm the version of Vuforia you have installed.

Thanks,

Vuforia Support

Hello,

Thanks for your answer.

Heres some screenshots. However, I can see in Xcode logs "Vuforia SDK version 7.1.31", not .34

Is it something you corrected since the .31 version ?

Hello Strasza, thanks a lot for your support.

I'm on OSX and do not use Unity Hub. Can you redirect me to a thread that describe the process to update to 7.1.34, or 7.1.35 ?

Thanks.

Okay, I found a simple way to update Vuforia SDK on OSX.

In unity, go to your Vuforia Configuration File (Assets/Resources/VuforiaConfiguration), il the right panel, the editor will suggest to update the SDK.

Click on the link, download and install the package.
