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.

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,

Build IOS vuforia 9.2.7

June 30, 2020 - 11:50pm #1


I've created empty test project using Vuforia (version 9.2.7) but I cannot build it under iOS.

My steps:

1) I create an empty project on Unity 2019.2.10f.

2) I add Vuforia 9.2.7 to the scene and then I add AR-Camera.

3) I build a project as the Xcode project

4) Then, I try to build IPA and get an error: "linker command failed with exit code 1"

Please explain to me how to correctly build a project for iOS.

Thanks in advance

Problem Clearflags changing in Unity Playmode

June 24, 2020 - 3:09am #1


I am currently working on my first Vuroria project in Unity.

I have created a virtual room that I would like to use as an AR app via IOS. For this I want the skybox to be displayed on a transparent Window instead of the Camera view. Therefore i chose Skybox as Clear Flags. As soon as I go into play mode, the camera switches the clear flags to solid color and I have a vertical stripe in the picture.

Am i missing something?
