Workaround for iOS Apps failing review

March 28, 2018 - 1:44pm #1


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).

Here are the recommended steps for installing and enabling:

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,

Hey there! 


I now already went through a lot of iterations of trying different combinations of either unity or vuforia. long story short: I always end up with the following error in XCode:

Cylinder target sample for native iOS

June 8, 2021 - 10:41am #1

In iOS sample project on Vuforia main site there's a sample for image target tracking. I tried replacing the target image with a cylinder target image I created with Vuforia Target Manager, but it does not work.

Does anyone have a sample native iOS project for cylinder image target tracking? I saw the sample for Unity on Vuforia main site but haven't figured out how to implement that for native iOS.

Thanks in advance!

How to track multiple image targets on iOS native simultaneously?

June 7, 2021 - 7:51am #1

Dear community / Vuforia support team,

we are currently struggling with the Vuforia examples for native iOS running with Swift/xcode and were hoping to get some hints here. We've implemented an application with multiple image targets (two for the test here) to be recognized successfully with Unity3D and SDK 9.8, but the same approach leads to bad results on iOS native. We've checked for the limits (VuforiaHint.HINT_MAX_SIMULTANEOUS_IMAGE_TARGETS, 100) and debugged our way through. But don't let me go into the code level now... my simplified situation with my questions would be:

When ios 14 or later, the screen changes to black and white and the tracking becomes unstable.

April 7, 2021 - 9:52pm #1

Apps that were successful in iOS 13 and earlier are updated to iOS 14 or later, and then the screen becomes black and white, and the recognition position is turned on strangely.

The Vuforia version is 8.3.8 and the Unity version is 2018.4.13f1.

What should be done?

Will version up of Vuforia solve the problem?

Video Playback Samples

March 12, 2021 - 10:23am #1


1. Can you please tell me where I can find the samples you provided in the past for video playing on a specific target? 

2. The old library (from 2014-2015 with that video playback feature) is still supported?

Vuforia SDK | Migration

March 9, 2021 - 6:35pm #1


I am creating this topic because I need to update an old project, which was built using Vuforia SDK: 5.0, with the latest version of Vuforia SDK for Unity.

Does anybody have a guideline, (step-by-step) process, to update a unity project with an older version of the SDK (like this one) to the latest version?

Additional data: Unity for mac version 2020.2.7 | XCode version 12 | iPad running iOS 14.4
