Build error. Anything else getting hit with this

Ive been hit with this error inside xcode on Unity 2018.4.13 and 2019.2.15 with two different projects. One project has hardly anything in it.

Code (csharp):

1.  
2. Undefined symbols for architecture armv7:
3.   "_OBJC_CLASS_$_PHPhotoLibrary", referenced from:
4.       objc-class-ref in iOSUtils.o
5. ld: symbol(s) not found for architecture armv7
6. clang: error: linker command failed with exit code 1 (use -v to see invocation)
7.  

I thought maybe doing a 64 bit build only would fix it but apparently not

Code (csharp):

1.  
2. Undefined symbols for architecture arm64:
3.   "_OBJC_CLASS_$_PHPhotoLibrary", referenced from:
4.       objc-class-ref in iOSUtils.o
5. ld: symbol(s) not found for architecture arm64
6. clang: error: linker command failed with exit code 1 (use -v to see invocation)
7.  

 

Yes I get similar errors with Unity 2019.3.0f3. Have you found out how to fix these?

 

Still no. trying to send my 600mb project into unity but my upload keeps timing out cause my internet is god awful.
will see if I can get it done today though.

 

Do you think it could be because 2019.3 to X-Code is not fully compatible?

I didn't get this error with a previous version of Unity 2019.3.
It could also be something on apple's side ;-S

 

I lost internet for 2 and half days so that kept me from submitting the bug to Unity.
Thanks for the information on that. I never tried with 2019.3

 

"PHPhotoLibrary" is a PhotoKit class of iOS SDK. You may have been using a third party plugin because Unity does not link PhotoKit.

To fix your linking issue, go to Frameworks and Libraries sections of your App Target settings (as shown below). Use the plus button to add PhotoKit reference.

 

Thanks Neonlyte,
I'll give that a try..

 

Post back when you try please.

 

Neonlyte It comes up with a search box. When I search PhotoKit it can't find it?

 

In my case the error was caused by the asset 'Universal Device Preview' I noticed there is a new update and it should be fixed.

 

Sorry for the late reply. It seems that PhotoKit also go by "Photos.framework". Give that a try.

 

I finally submitted my project to Unity about this error. Will post back. sorry for the long wait. Had to wait for my internet to get fixed.

 

Alright Unity support told me how to fix this.

For frameworks to be referenced automatically you'll need to mark them as dependencies at the plugin importer in Unity.
In your situation iOSUtils plugin causes these undefined symbols and it can be resolved by enabling "Photos" in the "Rarely used frameworks" tab.

so I searched IOSUtils in my Assets folder clicked on the file and clicked on "Rarely used frameworks" drop down list and checked Photos then hit import.

 

Thanks man, i had the same issue and it resolved for me!

 

Hejj guys - I can't find that Plugin? Is it in the asset store? could somebody link me that?

 

Did you hit apply after checking photos?

 

Sorry, I deleted my previous reply by mistake.
Now the problem has been solved, I have added "Photos.framework" in xcode, it's ok.


--------------------------------
my previous reply:
"Hello, I checked Photos and applied, but the error still exists, do I need any additional operations? I noticed you said "checked Photos then hit import ", but I don't see the import related button"

 

Are you having to do that in xcode on every build?

 

If I regenerate the xcode project, I need to manually add it once before building.

I found that other people have encountered similar problems : check the library in "rarely used framework", but it is not added to the xcode project

 

Odd I dont have that issue at all. Entire point of selecting that in the unity editor is so you dont have to select it in xcode.

What version of unity you using

 

I think so, feel weird too. the version of unity I using is 2019.4.27f1.
