iOS 14 + XCode 12 beta: Error getting TargetFinder

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()));

if (imageTracker != nullptr) {

    // Prints error: "Unable to set the RuntimeImageSource. The target width cannot be 0 or smaller."

    return imageTracker->getTargetFinder();

}

 

I'm using Vuforia SDK 9.4.6. I couldn't find any Cloud Reco example in the samples. Have the flow for cloud reco changed in this release? Have you experience that?

Hi spytar, totally agree, getting a valid TargetFinder instance was working just fine on iOS 13, but now it's not (there's not a single use case showing how cloud reco should work within the examples).

 

Vuforia team, u there?

Hi everyone! 

Someone has managed to verify that this functionality of Vuforia has been fixed on iOS 14 in v9.3.3?

In my project, which previously work on iOS13, does not work even though I downloaded the v9.4 of Vuforia. Did you think that in my case the problem is the v9.4?

 

Thank you in advance

Vuforia has fixed groundplane in iOS 14 in v9.3.3.

Please, take a look at the subject and description of this post: this is about TargetFiinder with latest Vuforia engine version on iOS 14

Groundplane not working on iPhone 11 Pro WITH iOS14 , Unity 2019.3.7, Vuforia v9.0.12 ! 

Before iOS upgrade to Version 14 everything was working fine on a multitude of different iOS Devices, as well as iPhone 11 Pro.

Will post next week if i am able to get more information on the error.
