Resolution for Vuforia 7 / iOS 11.3 black screen problem?

March 29, 2018 - 9:47am #127

I just recently upgraded my set-up to iOS 11.3 beta and Xcode 9.3 beta, since we need the enhanced capabilities of ARKit only available there. But Vuforia won't run in this combination, the app only shows a black screen.

I've seen that there's a sticky thread mentioning this known issue. But it is from February and still no solution?! Is there any workaround for this?

The sticky post also recommends to use Xcode 9.2, but with this version I cannot deploy directly to the device (only via organizer, which is quite cumbersome). So I would prefer to deploy using Xcode 9.3.

I, too, am affected, and this is coming at a time-critical moment when my company is trying to get an app (iOS 11.3, Vuforia 6.5, Unity 2017.3) out the door. It's a bit underwhelming how Vuforia support has handled addressing this issue or releasing updates regarding it.

I also have the black screen issue for iOS 11.3 (using Unity 2017.3, Vuforia and model target detection)

 

The issue only occurred when I upgraded my iPad from iOS 11.2.1 to 11.3. This also required an upgrade of xCode to compile and run on the new iOS.

I have the same problem. It appeared when I updated my iOS to 11.3, I have a Xcode 9.3 and ios sdk 11.3 (not Unity)

Please tell me how to fix this error.

Hello all,

I am working to get information about the plan for resolving this issue. I will update the forums as soon as I have any relevant information.

Thanks for your patience,

Seriously! the issue is known since February 5 and you still have no solution while the OS is already out? We have an ongoing project that needs to be distributed on ios and we are planning to subscribe to a license but we are going to abandon vuforia and work with ARKit instead.

Since we already have given our bucks for a commercial license, I thought should give my 2cents here.

You really to need this fixed soon. It already should have been fixed before the official iOS 11.3 and XCode 9.3.

Knowing Apple and the surrounding ecosystem it must be clear to you, that using an "outdated" versions is nothing most serious Apple developer are willing to do. Mostly  since Apple has a tendency of forcing new stuff onto developers.

So again, get this fixed.

Thanks

Hi,

I'm adding my "not so happy Vuforia developer" post here. We were considering buy the Vuforia commercial licence but during development we get stucked on iOS 11.3 because of this issue. I don't know why there's no update about this since 2 month since the OS version is now out, and our target device is now stuck in 11.3. Not any workaround or a hotfix.

We started to work on our own solution for AR in iOS, and we are delaying the licence buy because of this, maybe if we go Android someday. For iOS it really down our confidence over Vuforia support capacity, because if someday there's another major issue, we don't want to be stuck for another 2 month. And since the code source of Vuforia is almost completly locked, we can't get it fix ourselves.

Hope you'll find a quick fix, and good luck :)

Hello all,

We will be providing a patch for Vuforia 7.1 that will address this issue. We are actively working on getting this patch out the door and I will provide additional updates with exact timing in the near future.

With ARKit 1.5 beta, we found early on that Apple significantly broke our integration. However, due to the known timing of our 7.1 release and the unknown timing of iOS 11.3, we (blindly) moved forward with fixing the issue in our 7.2 release. Now that iOS 11.3 has officially release, we have escalated the need for a patch and it is currently underway.

Why not a patch for 7.0? With 7.0 SDK, Vuforia's direct integration with Unity also means we are dependent upon them for distributing patch releases. Our experience (so far) is that Unity has been slow to release patches for 2017.3. With Vuforia 7.1 (Unity 2018.1), we have created an installer function that decouples this Unity dependency and allows us to provide out-of-band patch releases.

Apologies that we do not have a 'quick fix,' but we are working towards getting the patch release out.

This user over on the Unity forums claims to have found a way to work around this issue if any of you would like to give that a try: https://forum.unity.com/threads/known-issue-when-developing-with-vuforia-7-xcode-9-3-and-ios-11-3-beta-arkit-1-5.516117/#post-3450395

Hi,

Thank you for your answer, it would be great if Vuforia can be updated without Unity.

Because not all project needs to keep Unity up to date, most of the time, we lock a version when we reach a critical milestone of the project. So if an issue like this happens and you have to upgrade Unity in a project that is already Silver, you are in some deep shiat :) Can you maybe get you include in their new "Package Manager" system (which seems to allow package to update themselves regardless of the Unity version) ? Or are you going to release patches on your website ?

I hope for a quick fix but it's good to know that this issue is finally getting the priority it needs.

Have a great day and thanks for your work

We are still seeing this problem using Unity 2017.3.0f3, Xcode 9, ios 11.3 (we are testing on an iphone 8) and Vuforia SDK v7.1.31. App and menu startup correctly but when the main scene with the AR camera and image targets is loaded the screen remains black and trackers are not tracked (UI is shown). The same project works for android phones and tablets.

Any workaround or fixes for this?

Thanks

This is essentially the plan starting with Unity 2018.1 + Vuforia 7.1 moving forward. We understand the tight coupling currently present causes issues such as the one you describe here and we are hoping the new approach will alleviate that.

I am also having this issue which is extremely frustrating as I am ready to ship an update to my iOS app. Vuforia charges (in my opinion) quite a high price for a commercial licence. The fact that their SDK doesn't work with a current version of iOS is simply unacceptable. 

With that out of the way can someone please tell me if there is anything I can do to fix this, here is my setup :

  • Unity 2017.3.0p3
  • Vuforia 7.1.31
  • I have removed the unity ARKit package contents from my project
  • Xcode 9.3

Using vuforia arcamera and image targets results in a black screen

Same problem here and having to upload a customer app right now, so no time to wait for an update...

But as mentioned by a Vuforia support team member, this solution is working: https://forum.unity.com/threads/known-issue-when-developing-with-vuforia-7-xcode-9-3-and-ios-11-3-beta-arkit-1-5.516117/#post-3450395.

To recap:

1. Download Xcode 9.2 (https://developer.apple.com/download/more/)

2. Copy /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/11.3 (15E217) to your new (old) Xcode 9.2, for exemple: /Applications/Xcode\ 9.2/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport.

3. Rename 11.3 (15E217) to 11.3, and 11.2 (xxx) to 11.2 in your Xcode 9.2 DeviceSupport folder.

4. Build your unity project.

5. Open your project with Xcode 9.2. You can now build for your iOS 11.3 iPad without having this black screen.

Best.

Is it planed to bring out Vuforia 7.0.x for 2017.4 ? A long term supported version that will not be able to get quick fixes... is not a good option.

Hello Straza,

any news about the fix? It's been a long time since the issue is known and Xcode 9.3 + iOS 11.3 are officially launched. I agree with the user above that commented on how Apple ecosystem quickly adapts to newer versions. Our product is complex and requires integration with a lot of swift native code and this problem is holding us back on our migration to Xcode 9.3.

To be honest since Vuforia started to ship together with Unity it has been a nightmare for us. I understand that it makes things easier to starting developers, but remember that there is also the problem with the auto-attach camera script that you haven't patched yet and the haunting sample files that are copied into my project every single time!

Please, revert to the old way: Vuforia as a separate plugin and no automatic configurations/attachments and integration code open so we can work around problems like this asap!

You'll need Vuforia 7.1.34 for the fix for this issue. Unity 2018.1.0f1 or later (the commercial release) will have the download option for this. You can get it to work with 2018.2, but due to this version being integrated with the Unity Hub, you'll need a couple extra steps.

I can confirm we are using 7.1.34, xcode 9.3 and unity 2018.1.0f1 - After spending all day yesterday looking at the Xcode logs and removing things from the unity scene, the main cause of our issue is the UI Canvas component in Unity. Project works fine without a Canvas in the Unity Scene - as soon as we add one, the Vuforia camera renders black and the below Xcode log shows

I must stress that this issue appears to be specific to our Ipad Air models running IOS 11.3, our Ipad Pro and iPhone models on 11.3 run the app with no problems - using an iphone 6s, iphone 7 and iphone x.

As mentioned on other threads in this forum - if you are using Unity, go to player settings:



Change the graphics API from Metal (or automatic) to GLES 3.0 or GLES 2.0 to fix this issue in unity.



You're welcome ;)

So I've been able to get my app working once I went with the Xcode 9.2 hack for 11.1 and forward. Problem I'm having now is that the app will work for a day or 2 but then it will kinda crash on startup. Kinda crash meaning it will return to the homescreen after a frame of black but I will notice that it's working/rendering when I double click home and see the preview with my UI and camera feed. But I can't switch to it as it will soft crash again to the background. Anyone else notice anything like this lately?

What device are you using? Also, what elements are in your scene - is there a Unity UI Canvas?

Hello pant76,

It is recommended to use XCode 9.3 as that is the latest release and later versions are in beta and un-tested. Without further information on the issue you are having there is not much for us to do to assist. Can you share any relevant log data from your issue? Are you able to reproduce this within the samples? Are you on Unity or native? Which version of Unity and Vuforia?

Thanks,

Vuforia Support
