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,

Xcode 11.4+ (Xcode 12) Simulator error : "Building for ios simulator but the linked library libvuforia.a was built for ios"

September 23, 2020 - 3:12am #1

My iOS app uses Vuforia, i used to work fine on simulator with the optional option for the framework libVuforia.a.

Now, I jsut updated to Xcode 12, and this new version doesn't handle frameworks like it used to. It tries to embed the iOSonly libVuforia.a on the simulator build, and makes this error : "Building for ios simulator but the linked library libvuforia.a was built for ios"


Has anybody found a workaround for this ? Is there an official recommendation on this matter from the Vuforia team ?

September 15, 2020 - 7:24am #1

Hi there, we're tuning our apps for iOS 14, and we're experiencing an error when we init the cloud reco flow (same codebase that was working fine before).

Vuforia::TrackerManager& trackerManager = Vuforia::TrackerManager::getInstance();

Vuforia::ObjectTracker* imageTracker = static_cast<Vuforia::ObjectTracker*>(trackerManager.getTracker(Vuforia::ObjectTracker::getClassType()));

Simultaneous image detection

August 18, 2020 - 9:46am #1

Hi All,

I successfully run the sample IOS app (vuforia-sdk-ios-9-3-3.zip) by following the instructions in https://library.vuforia.com/articles/Solution/Getting-Started-with-Vuforia-for-iOS-Development.html

It is detecting the stone image quickly.

My Question is, Is it possible to detect multiple stone images simultaneously ?
