Failed to resolve image library - XCode iOS

Unity Engine

So I make an app for Android and iPhone. The app itself has no any differences feature or code in both platforms. I’ve no issue when I deploy it for Android but then when I try to build it for iOS, these errors come out :

The app is successfully built, but can’t track any image.

The thing is I have no idea why this could happen, because I already assign the ‘ImageLibary’ in Unity inside MARSSession.
Can someone help me with this issue? I’ve been stuck for almost 1 week just to figure out the solutions…

Thank you so much7570942--937522--Screen Shot 2021-10-14 at 12.22.05.png 7570942--937528--Screen Shot 2021-10-14 at 12.21.30.png

EDIT : Currently using Unity 2020.3, MARS 1.3, and XCode 13

Hey there, Seems you have an issue with the marker library; could you check that on your MARS Marker library you have next to it a file with the same name that ends in _arf ?. MARS needs both to work.

Also, could you tell us if this also happens on latest Mars 1.3.1?

Thanks for the reply.

Yes I have both MarkerLibrary in the same folder…

I’ve tried to update the MARS version to 1.3.1 and still with same result…

Hey there!,

Could you check if it happens on an empty project with just image markers?

5

Yeah I did that too. I’ve made a simple image tracking with just a cube shown up. And it’s still same…

Thats quite strange; could you tell us what version of ARFoundation ARKit and ARCore are you using?, also ARF providers. Are you able to check if this still happens on XCode 12.5?. Which version of XCode 13 are you using, final release or a Beta. (And if its a beta, which Beta)

7
  • AFoundation 4.1.7
  • ARKit 4.1.7
  • ARCore 4.1.7
  • AR Providers 1.3.1

Nope, I haven’t try it on XCode 12.5, and for XCode 13 it’s full release version already

8

We are looking into this, could you please try it out with XCode 12.5 just to cover al bases?

Ok, I’ve tried it and still same as before…

I also have tried to build an empty scene with ImageLibrary attached in the MARSSession and got different error.

I’ve been unable to reproduce this (with XCode 13) - would you be able to file a bug report (Help → Report a bug…) from one of your projects that has the error? That’ll help us track it down.

I think I have solved this issue; I hope this helps!
