Can you share more details about having to relink your paths in Xcode? Are you using 3rd party Unity plugins?

When I go from Unity to xcode my library search path to Plugins comes in funny instead of a "/" it comes in with a "\" I am using a clean scene with Vuforia as my only plugin. I can get my app on the Ipad and the camera works but won't recognize the image targets. I saw that in the debug it says it can't load or activate the dataset and assumed that is the reason why no models pop up on the images.

I am experiencing this problem as well. I can track the image targets in Unity using my webcam, but nothing appears when using any of my ios devices.

A couple of questions:

• Does the ImageTargets 4.0.105 sample compile and work okay?
• Are you compiling the Xcode project from the Windows version Unity?

Yeah I was building it on windows and transferring it to my Mac. After I switched to Mac it worked. Why can't I build Vuforia on windows for a Mac????

Yes, building an iOS Vuforia Unity project on Windows and compiling with Xcode on a Mac is not supported. I don't have any more technical explanation than that. There's been other posts on the forums about this as well.

has this been solved by now so that it is possible to build working vuforia ios solutions on unity-windows and then just to have to compile finally on mac?

Same probrem occuered on my iOS device.

- OS X 10.10.5

- Unity 5.2.1f

- Vuforia 5

Same project can build Android, its work.

But, iOS (9.0.1) device couldnt work.

I dont use windows.

Xcode said...

```

dataSetExists

Dataset ______ could not be loaded and cannot be activated.

```

why?

• Are you able to build and run the ImageTargets 5.0.5 sample app successfully?
• Are you using multiple datasets?
• Is the dataset activated on the ARCamera?

I also can't make it work on iOS.

As previously mentioned, I get the following message:

dataSetExists

dataSetExists

Dataset __________ could not be loaded and cannot be activated.

Any idea on how to solve this issue?

Maybe the path to the folder with your project contains non-English characters? Check it plz.

Hi, I actually have the same issue in our iOS build (Development and Production):

dataSetExists
dataSetExists
Dataset DBTestV1 could not be loaded and cannot be activated.

I tried different names for the DataSet (db_test_v1, db-test-v1, DBTestV1), but the problem is still here, on any iOS platform (tested on iPad 4, iPhone 4S and iPhone 5)

It works in Unity Editor, Android (tried on multiple smartphones and tablets) and PC / Mac, but iOS is the only platform I can't make it work.

ARCamera is present in scene, Load Data Set and Activate checkboxes are both checked.

Image Target Textures are in folder Editor/QCAR/ImageTargetTextures/DBTestV1.

DataSet (both DBTestV1.dat and DBTestV1.xml files) is in folder StreamingAssets/QCAR.

Versions:

Unity 5.2.0f3

Vuforia 5.0.5

Xcode 7.0.1

Are you able to compile and run the ImageTargets 5.0.5 sample app?

Hello,

Yes, the last ImageTargets sample app works on my iPad, so I tried to compare my project folder with the sample folder and noticed that the file PostProcessBuildPlayer was missing in my project... -_-"

After copying this python script in my Editor folder, it now works perfectly !

Does it help for anyone else? I have this script in Editor folder, but no result

What worked for me was that I manually added the following compiler directive to the ARCamera's LoadDatabaseBehaviour script under the AddOSSpecificExternalDatasetSearchDirs function:

#if UNITY_IOS

    AddExternalDatasetSearchDir(Application.dataPath + "/Raw/QCAR/");

#endif

This is an iOS specific fix that explicitly points to the Streaming Assets folder in the iOS build itself.

My versions & info:

Unity version: 5.3.0f4

Vuforia version: 5.0.6

OSX version: 10.11.2 (El Capitan)

Xcode version: 7.2 (7C68)

iOS device: iPad mini 3

iOS version: 9.1

that worked out for me! thanks 

that worked out for me! thanks

It works even if the compilation has been done before on windows?

haven't checked that case, I had dataset issue after updating Unity on OSX 

My project came from Windows and with this, it is working correctly now.

What is the solve?

Hi, your answer looks great but I can't find the script you're referring to.

I don't have a script on my ARCamera called LoadDatabaseBehaviour, I only have: 

• QCARBehaviour
• DefaultInitializationErrorHandler
• DataSetLoadBehaviour
• SmartTerrainTrackerBehaviour
• WebCamBehaviour
• KeepAliveBehaviour
• VideoTextureRenderer

Can you please help? Many Thanks

I think they're referring to DataSetLoadBehaviour.cs

is there a similar solution for UNITY_WSA devices?
