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,

Difference in tracking quality on iOS

February 3, 2021 - 12:57pm #1


We had made a Vuforia AR Project, on Unity Engine 2019.4.14.f1. The problem is - tracking and detection quality on Android and iOS builds differs. Some ImageTargets are recognized on Android build alright, but the same ones are completely ignored in the same project build for iOS. We make builds from the same Unity project, and had enabled Vuforia Fusion for better compatibility with native AR SDKs. Also, we forced enabled ARCore requirement in Vuforia settings, and ARKit requirement in Unity project settings.

iOS App Clip, <10Mb binary size

January 25, 2021 - 6:44am #1

I am working with a customer to create an app clip of their AR application. The maximum allowed binary size is limited to 10Mb, which is way less than the size of Vuforia binaries.

Are there any plans to release Vuforia as multiple, smaller libraries (e.g. like Google Firebase does), one for each feature. I only use image targets and cloud recognition, for example. 

Thanks, Alessandro
