Code signing error on IOS with libdracodec_Unity.bundle

[aribot-hrv]

When publishing on apple store, the app code signing failed.

The issue is caused by wrong configuration of the OSX bundle on Unity :
Runtime/Plugins/x86_64/dracodecunity.bundle
Target defined on metadata file is for all targets instead of OSX only.

I got the exact same Problem. Did you find a solution? Unity doesn't let me change the platforms for dracodecunity.bundle. It always gets reverted to Any Platform.

Hi,

Thanks for bringing it up!
This is a macOS security feature trying to prevent running unsigned (and thus possibly harmful) code. I'd have to setup the CI to do code-signing. This requires enrolling in the Apple developer program costing 100$ per year, which is why I didn't do it so far.

Here's the steps to get around it:

1. When you first open a project with DracoUnity (or add the package), you get prompted to remove the "broken" ktx_unity.bundle. Don't do it and click "cancel" instead.
2. Open the macOS "System Preferencess" and go to "Security & Privacy". At the bottom of the "General" tab you should see a warning about ktx_unity.bundle. Click the "Allow anyways" button besides it.
3. Restart Unity
4. Now you get another, similar prompt (see step 1) with the third option "Open". Click it
5. Now it should work (at least for development on your machine)

If you want to deploy your software using DracoUnity you either have to

• Wait until I have proper code-sign setup (I'll close this issue in that case)
• Build your own library from this source draco repository and sign it with your own credentials/Apple profile.

I hope that helps,

Andi

Hi @atteneder,

thanks for the answer, but i don't use Unity in macOS, nor do try to build a macOS app with DracoUnity. I try to build the app with DracoUnity for iOS Devices on a Windows PC an then publish the app with XCode on a Mac.
My workaround to publish the app successfully, was to delete the dracodec_unity.bundle folder in /Runtime/Plugins/x86_64/ rebuild the XCode project and publish it again from XCode on the Mac. However, after restarting unity, the deleted folder gets automatically added to unity again. Is it possible to prevent that from happening?
Also isn't it possible to change the platform configuration (image below) to standalone only?

Hi @chrisssssy

never tried that combo, lol (downloading iOS module on win right now)

changes to the package are not preserved if it's installed via package repo. And that makes sense. Packages are not part of the project itself. You can shoot yourself in the foot easily by making accidental changes and forget them.

If you want to develop/change a package, install it via GIT or locally (e.g. download the repo as ZIP)

The settings in your screenshot are not what I see. It's Editor and Standalone only here. Did you make an accidental change?

Note: You can't even change the DLL settings. It's a bug that you actually can change the bundle settings, imho.

Even with iOS module installed and removed and re-added the DracoUnity package I get this:

How did you install DracoUnity? Please try the recommendet variant via OpenUPM (see reamde)

[chrisssssy]

I am not shure anymore how i installed it, but it's in the package manager and the registry is OpenUPM.
However i could make an update in the Package Manager from version 1.3.0 to 1.4.0 and that seems to fix the issue. Now the selected platforms are editor and standalone only, like in your screenshot.

[atteneder]

Oh, that makes sense. I must have fixed it along the way.
My assumption, that code sign is to blame, are likely wrong => closing
Thanks a lot for the report!
