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,

Is it possible to save screencapture to iOS Photos Library

March 16, 2019 - 7:40pm #1

As we work on developing our proof of concept, the one functionality we would like to add is to be able to save a screencapture image, including the AR overlays to the iOS Photos Library.

The Unity API does provide a "screencapture" function which can be called. The Unity documentation indicates the when used in the Unity, the image is saved to a predefined path as predefined by the application.persistentpDataPath function.

Image from Image Target

March 11, 2019 - 4:15pm #1

Hello everyone,


I'm working on a iOS project with Vuforia and more specificity the User Defined Targets.

From what I can see in the sample app when the user presses the camera button an image target is created.

In the method:

- (void)renderFrameWithState:(const Vuforia::State &)state projectMatrix:(Vuforia::Matrix44F &)projectionMatrix


I was able to extract the unique ID for the created ImageTargetResult
