Known issue when submitting an iOS build to Testflight with Vuforia 7.2.20

July 12, 2018 - 11:17am #1

Hello all,

There is an issue with Vuforia 7.2.20 that will prevent you from uploading your iOS app to TestFlight. The cause of the issue is that the “Bundle Version” field of the Info.plist in the Vuforia.framework is blank. This issue can be worked around by opening the Info.plist file and adding a number value, such as “1,” to this field.

Attached is Vuforia’s version of the app-level fix scripts provided by @adrianj (many thanks!) in the following forum thread. This can be used immediately with SDK 6.5 (Unity 2017.2), SDK 7.0 (Unity 2017.3) and SDK 7.1 (Unity 2018.1).

Known issue when developing with Vuforia 7, Xcode 9.3 and iOS 11.3 beta (ARKit 1.5)

February 6, 2018 - 8:52am #1

Hello all,

There is a known issue when using:

  • Vuforia 7
  • Xcode 9.3
  • Devices running iOS 11.3 beta && support ARKit (version 1.5, bundled with iOS 11.3 beta)

When developing with these versions, you may observe a camera preview that renders a black screen.

This is being addressed in an upcoming release of Vuforia. In the meantime, it is recommended to use Xcode 9.2 (or earlier) to ensure development continuity.

We will provide an update once the issue has been resolved.

iOS UIView issue

December 1, 2017 - 10:53am #1

Hello all,

I wanted to bring to attention an iOS issue you may encounter that will cause reduced performance within your app. This can occur either with native iOS or Unity development.

In native development, if you are not using a storyboard, you’ll need to set the ‘backgroundColor’ field of any UIView you generate with code to ‘UIColor.clearColor’ to get around a known iOS issue. If you are using a storyboard, you will not encounter this issue and will not need to add any code.

Video Playback Streaming Render To Texture

October 13, 2014 - 12:04am #1


I would like to have some video streamed and played on top of a recognized image, not in full screen. The vuforia samples as of this date do not seem to indicate that something like this is possible, or at least, they haven't created a sample with that.

I found this link,

UnauthorizedAccessException: Access to the path [ios/ Mac os Mojava / Unity 19.2.0] failing to build project

September 18, 2019 - 8:32am #1

I was able to build the exact same project on the exact same Macbook pro last week but now I no longer am and I don't understand why.

Now when I first open the project (I am primarily working on a windows computer for the android version of this project, using the mac just to make builds) it says:

Integrate SceneKit in Vuforia iOS SDK

September 4, 2019 - 10:29pm #1


I need to animate 3D objects (OBJ files having MTL file as well, also other formats) on top of image targets. So, I need to use SceneKit instead of OpenGL (which is given in their Teapot demo). We have beed exploring and trying to achieve that by replacing OpenGL with SceneKit but we found it hard to implement.

iOS App Lags when Track Device Pose is enabled

September 2, 2019 - 5:37am #1


weve build a prototype app which has been created with Unity 2019.1.14f1 and Vuforia 8.3.8.

When we enable "track device pose" with the tracking mode set to "positional" the app starts to lag on iPhone 6 and iPhone 7.

Were using image targets. The overlays move along with the iPhone when its being moved. When track device pose is disabled everything runs smoothly. 

We did not run any tests with iPhone 8 and 9 but with iPhone 10 there is no more lag occuring. Does the setting consume to many resources on older iPhones?

iOS 13-beta Vuforia+SKVideoNode+AVPlayer shows black screen

August 28, 2019 - 6:51am #1

Hi, my app is a AR app, we use Vuforia to recognize image and use SceneKit to play video.

We created SKVideoNode by AVPlayer and set the SKVideoNode to SKScene, and then create SCNNode to involve this SKScene.

- Sample Code


    AVPlayer *avPlayer = [self getMoviePlayer:path];

    SKVideoNode *videoNode = [[SKVideoNode alloc]initWithAVPlayer: avPlayer];

    CGSize videoSize = CGSizeMake(100, 50);

    videoNode.size = videoSize;

    videoNode.position = CGPointMake(50, 50);
