Xcode build Error : 'UnityFramework/UnityFramework.h' file not found

When I am trying to build the Xcode project, it is saying that my main.mm can not find the UnityFramework.h file. Which I checked is not missing in the Project. Can anyone give me some advice on what to do?

 

I have the same error. Not sure what to do.

 

This is known issue with Helpshift plugin (and with all plugins that use OLD mod_pbxproj). You can fix this by modifying mod_pbxproj.py file by adding

Code (CSharp):

1. ('PBXHeadersBuildPhase', True),

to line 1349 (or near it, depending about the mod_pbxproj version)

 

Hello everyone,

I don't have any mod_pbxproj.py in my project, so I have to update the main.mm manually. Is there any other way to change that ? (I just update the path so!)

Thank you !

 

You can create post process script that modifies the file manually. Something like

Code (CSharp):

1.  
2.     [PostProcessBuild]
3.     public static void ChangeXcodePlist(BuildTarget buildTarget, string path)
4.     {
5.         if (buildTarget == BuildTarget.iOS)
6.         {
7.             // Ugly fix for missing UnityFramework.h Xcode issue
8.             string mainAppPath = Path.Combine(path, "MainApp", "main.mm");
9.             string mainContent = File.ReadAllText(mainAppPath);
10.             UnityEngine.Debug.Log(mainContent);
11.             string newContent = mainContent.Replace("#include <UnityFramework/UnityFramework.h>", @"#include ""../UnityFramework/UnityFramework.h""");
12.             File.WriteAllText(mainAppPath, newContent)
13.          }
14. }
15.  

 

Hello Kaarloew !
Thanks for the reply .

I don't have access to my mac OS machine, but I'm totally going to do that! I started modifying the file by hand and I was close the getting it to work!

Thank you for your help!

 

Hello @kaarloew where I can read more info how to implement such script in my unity project ? I mean is it just writing script and then I run build in Unity ?

 

Yes. You can read more about the PostProcessBuild in https://docs.unity3d.com/ScriptReference/Callbacks.PostProcessBuildAttribute.html

 

I have the same error. It started after I cleaned the project in xcode. I have spent all day on that error please help!!!

 

Ok I finally got it! You can change the code in main.mm by hand. I changed it from <UnityFramwork/UnityFramwork.h> To "../UnityFramwork/UnityFramwork.h"

 

Dude, its framework not framwork -

Code (CSharp):

1. #include "../UnityFramework/UnityFramework.h"

 

Dude, UnityFramwork for days.

 

This worked for me!! After 9-10 hours of searching for a solution to this error: 'defines.h' file not found
Probably will use the post process script for new builds, but changing the main.mm file in xcode was simple enough to test it.

 

I can't explain exactly why this happened, nor why my solution worked, but I found that in my Products folder, there were multiple folders. One was "ReleaseForRunning-iphoneos" - that's the one from which Xcode was building. That one didn't contain the UnityFramework folder, but another - "ReleaseForRunning-iphonesimulator" did. I copied that folder over (it's all for the same app after all, right?) and the build succeeded.

 

After fiddling with this same problem for an hour or two, I solved by just clearing the build folder.

 

where is this file located?

 

After fixing this issue I have another issue with unityappcontroller.h file is not found.

 

i am getting this error while include this ->
#include <UnityFramework/UnityFramework.h>

Error ->UnityFramework/UnityFramework.h' file not found..

Please Help me out

 

A recent version of Unity (2022.3.18 onwards) broke IOS builds if using IOS Project Builder. Also broken in the current Unity version. I am posting the error below (for anyone searching the internet for a solution to this problem) and the fix below that.

In file included from .\MainApp\main.mm:1:
.\UnityFramework/UnityFramework.h(4,9): fatal error: 'UnityFramework/UnityAppController.h' file not found
#import <UnityFramework/UnityAppController.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
+ [arm64] Linking <my app name>...
ld64.lld: error: cannot open build/Release-iphoneos/iPhone-target/arm64/./MainApp/main.mm.obj: no such file or directory
ld64.lld: error: undefined symbol: main

To fix, add this code in a file like Editor/PostProcessBuildClass.cs:

Code (CSharp):

1. static class PostProcessBuildClass {
2.   [PostProcessBuild]
3.   public static void ChangeXcodePlist(BuildTarget buildTarget, string path) {
4.     Debug.Log("Post process build ChangeXcodePlist");
5.     if (buildTarget == BuildTarget.iOS) {
6.       string mainAppPath = Path.Combine(path, "UnityFramework", "UnityFramework.h");
7.       string mainContent = File.ReadAllText(mainAppPath);
8.       string newContent = mainContent.Replace("#import <UnityFramework/UnityAppController.h>", "#import <Classes/UnityAppController.h>");
9.       File.WriteAllText(mainAppPath, newContent);
10.     }
11.   }
12. }
13.  

 

I'm my scenario, for some reason using Unity 2022.3.20f1 I had to ad both patches.
The main.mm and UnityFramework.h

 

Baldrekr - thank you - just recently upgraded unity and ran into this - your fix worked perfectly. Just hope I remember to remove it after I update to a fixed unity or ios build tool!
