Camera don't work on iOS device

May 28, 2018 - 8:53am #1

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.

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.

Your project Vuforia files won't be refreshed. To do so, create a new project, place a Vuforia gameobject in it (ARCamera for example), Unity will install Vuforia components. When done, copy/paste the content of Assets/Vuforia from your new project to your real project.

@Strasza, with 7.1.35, everything works perfectly on iOS. Thanks !

PS: this thread should be closed now, but i cannot figure out how...

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.

How can this be done for Unity 2017.3.1? Upgrading to Unity 2018 won't work for us, but we need proper Vuforia support on iOS 11.3+

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 ?

I have installed Vuforia with the Unity 2018.1.2f1 install wizard, as recommanded in your website.

 

You'll need version 7.1.34 to resolve this issue. You can update it through the Vuforia Configuration. There are a couple threads in the Unity and iOS forums here that describe how to upgrade this if you face issues.

Thanks,

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

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'll see if I'm able to reproduce this on the same setup you described in your original post.

Thanks,

Vuforia Support

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?

Check the sticky post

https://developer.vuforia.com/forum/unity/known-issue-when-developing-vuforia-7-xcode-93-and-ios-113-beta-arkit-15

 

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

then just build and run from 9.2

(I'm on unity 2017.3.1 but the fix might still apply)
