I see two frameworks in your screenshot, one of which is UnityFramework.framework. That looks like what I would expect for the "Unity-iPhone" target. Can you explain what you were expecting?

Thank you tdmowrer for your reply.

My Ar application working fine in Unity 2019.2.16f and also I can see all the related frameworks in Xcode. Recently I get to know Unity 2019.4.2LTS was released, so I tried one sample project before converting my project. I have tried the AR sample project with Unity latest version 2019.4.2 & 3, after making build I am unable to see all frameworks in Xcode related to AR Foundation, AR Kit, etc... When deployed this build into my iPad I am unable to see the AR camera. I have given all permission related AR you can see in the attached screenshot. In the screenshot framework, I have added the MessageUI framework manually. Please let me know why I am unable to see all frameworks on 2019.4.2/3 is there any problem with this version..?

iPad version : - 5th gen Xcode version : - 11.5 Unity3d version :- 2019.4.2 & 3

In 2019.3+, the Unity Xcode project is a bit different. Instead of a single application, it is split into an application and a UnityFramework.framework. All your previous frameworks were probably added to the UnityFramework target, e.g.:

Ok..So Can you please tel me what is the problem it's not showing anything on my sample app.

I have tried to open my project on this version it showing this error.

Assets\Editor\BuildPostProcessor.cs(20,33): error CS0619: 'PBXProject.GetUnityTargetName()' is obsolete: 'This function is deprecated. There are two targets now, call GetUnityMainTargetGuid() - for app or GetUnityFrameworkTargetGuid() - for source/plugins to get Guid instead of calling to TargetGuidByName(GetUnityTargetName()).

I changed the script with

if UNITY_2019_3_OR_NEWER

        string targetId = project.GetUnityFrameworkTargetGuid();

else

string targetId = project.TargetGuidByName(PBXProject.GetUnityTargetName());

endif#if UNITY_2019_3_OR_NEWER

        string targetId = project.GetUnityFrameworkTargetGuid();

else

string targetId = project.TargetGuidByName(PBXProject.GetUnityTargetName());

endif

Still no result.. :(

A UnityEngine API did change in 2019.3 and the packages were updated appropriately.

What version of the ARFoundation packages (ARFoundation, ARKit, ARSubsystems) are you using?

[eswarborra]

ARFoundation, ARKit, ARSubsystems,AR Core packages version: 4.0.1

[tdmowrer]

Ok, great; those are verified (i.e., "stable") and they work in 2019.4 (the samples in this repo were built with 2019.4 and use 4.x packages, for instance).

You have posted both an error encountered while building within Unity and a linker error while building within Xcode. Neither appear related to ARFoundation. Let's take them one at a time:

Assets\Editor\BuildPostProcessor.cs(20,33): error CS0619: 'PBXProject.GetUnityTargetName()' is obsolete: 'This function is deprecated. There are two targets now, call GetUnityMainTargetGuid() - for app or GetUnityFrameworkTargetGuid() - for source/plugins to get Guid instead of calling to TargetGuidByName(GetUnityTargetName()).

Your suggested code change should fix this particular error. Did it?

You also posted a screenshot of a linker error from Xcode:

This is not related to ARFoundation, either, and I'm not familiar with the MFMailComposeViewer.

Typically, when you upgrade from an older version of Unity, you need to "Replace" rather than "Append" to an existing Xcode project. (That is, click Build & Run and then "Replace").

However, as far as I can tell, the errors are unrelated to ARFoundation and are coming from scripts or other dependencies in your project.
