Bug Both Unity and Iron Source Mediation fails to build on Xcode with protobuf bitcode error

Hi,

I tried both with Unity Ads with Mediation and also with Iron Source mediation, I get the below error.

ld: '/Users/myuser/Library/Developer/Xcode/DerivedData/Unity-iPhone-atgpqaqhdoftguekjshddinoqwwc/Build/Products/ReleaseForRunning-iphoneos/Protobuf/Protobuf.framework/Protobuf' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/myuser/Library/Developer/Xcode/DerivedData/Unity-iPhone-atgpqaqhdoftguekjshddinoqwwc/Build/Products/ReleaseForRunning-iphoneos/Protobuf/Protobuf.framework/Protobuf' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Here are the versions I have;

xcode 14.1
unity 2021.3.13f1
iron source v7.2.5.1
unity ads with mediation 1.0.5
cocoapods 1.11.3

I use a MacBook Pro with M1 Pro chip.

Thanks

 

I have the same error.
I have the same libraries versions and the same XCode.
And the same - error appeared after I added mediation service.

Enabling/disabling bitcode option didn't help me.
I've added a screenshot to show a place where I worked with this option.
(I tried all combinations both for Unity-IPhone and Pods).

 

Hello, I also have kinda the same, it worked well and stopped working since I added IronSource.

'/........./IronSource.framework/IronSource(ISEventsConfiguration.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '......../IronSourceSDK/IronSource.framework/IronSource' for architecture arm64

I'm used to the trick @DeclanMcPartlin suggested but it does not work with this specific issue.

 

Any updates on this? Getting the exact same issue.

 

Hi! Did you manage to solve the problem?

 

Having the same problem on Xcode 13.4.1

 

Any update on this ? Enabling bitcode isn't making a difference

 

this is the same problem with unity cloud build also

Enabling/Disabling BITCODE in Build config doesn't help

 

build #50
xcode 14.1
unity 2021.3.16f1
ruby 2.42
clean build

running this script to disable bitcode in root editor folder

#if UNITY_IOS



using UnityEditor;

using UnityEditor.Callbacks;

using UnityEditor.iOS.Xcode;





public static class BitCodeHelperRevised

{

    [PostProcessBuild( 1000 )]

    public static void PostProcessBuildAttribute( BuildTarget target, string pathToBuildProject )

    {

        if (target != BuildTarget.iOS) return;

        var projectPath = PBXProject.GetPBXProjectPath(pathToBuildProject);



        var pbxProject = new PBXProject();

        pbxProject.ReadFromFile(projectPath);

        var targetGuids = new[] { pbxProject.GetUnityMainTargetGuid(), pbxProject.GetUnityFrameworkTargetGuid() };



        pbxProject.SetBuildProperty(targetGuids, "ENABLE_BITCODE", "NO");

        pbxProject.WriteToFile(projectPath);

    }

}



#endif

RESULTS - no longer shows bit code errors but still fails.

UPDATE! I HAVE SOME AMAZING NEWS (SORT OF)

After uninstalling ironsource packages then fresh install and leaving out UnityAds from the Integration Manager, I can now say that it completed the build in cloud build.

xcode 14.1
unity 2021.3.16f1
ruby 2.42
clean build

and using the script in my above post for turning off bitcode.

 

update:


project version 2021.3.16f1

ios target 12.0

cloud build settings (build # 61)

Xcode 14.1.0

unity 2021.x

UnityAds(ironsource manager) (Installed) 4.3.29.1

ironSource 7.2.6

ruby 2.7.4

bitcode disabled

^^^^ Build was successful

For cloud build it was updating ruby to 2.7.4 for a successful build or leaving out unity ads from integration manager and using ruby 2.4.2.

 

Apple is dropping the bitcode requirement, starting with Xcode 14. Apple never really used bitcode, and it's been a massive PITA for us Unity developers. I'd recommend disabling it all together to make your life easier.

I added a Fastlane plugin to my Jenkins builds to do just that: no_more_bitcode

For Unity, you need to call the plugin on the main and the Pods projects. Here's an example from my Fastfile.

Code (boo):

1.     private_lane :disable_bitcode do |options|
2.         no_more_bitcode( xcode_project: @xcode_output + "/Unity-iPhone.xcodeproj" )
3.         no_more_bitcode( xcode_project: @xcode_output + "/Pods/Pods.xcodeproj" )
4.     end

Read more details on the horrors and waste of time that was bitcode.

 

I don't need ironsource right now. Only thing what causes this bug. What worked for me was to go to packages look up ads mediation. Uninstall, then install again then uninstall again. I think it got glitched with xcode 14. Then delete the ironsource folder in the project. Then build the project, enable bitcode on pods = true. Run it once on a phone, then set Always Embed Swift Standard Libraries to NO at frameworks. Then you can finally archive and publish.

Got to love unity adoptions and abandonments. Wasted a whole day on this.

 

For IronSource, the build was successful after setting all the bitcode to NO, including UnityIphone & UnityFrameworks

 

[SOLVED]
I've turn off bitcode of all target, build success but app crash immediately after open.

Then please don't turn off all the bitcode if you don't know what it is, like the firesightstudios's answer before. Just turn off bitcode of true target and it will build success.

For me:
Step 1: Turn off bitcode for Unity Framework
At this step, if it build fail due to Unity Framework issues, that because there are some swift's library that do not auto includes when building. Just do these things to include them:
- Select Unity Framework target -> Build Settings -> search for "library search path"
- Add the library uri:

Code (Boo):

1. $(SDKROOT)/usr/lib/swift
2. $(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)

Step 2: Turn on bitcode for Pods-Unity-iPhone
Step 3: Turn off bitcode of all other targets in Pods

Build Successfully! Play like a boss!

 

I'm encountering the same error and I have tried the solutions above (disabling bitcode, turning it on for pods).

We are using
XCode 14.3
Unity 2022.2.8f1
Iron source v7.3.0
Unity ads with mediation 1.0.5

Our PostProcessor code also has ENABLE_BITCODE = NO.

I then get an error saying

File not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphoneos.a

 

I spent two days figuring out how to make Unity LevelPlay work with IronSource, and here's what worked for me. I had to combine three methods that I found on the forum.

1. Disable BitCode by using the following code in Scripts/Editor/BitCodeHelperRevised.cs (huge thanks to @firesightstudios):
   
   Code (CSharp):

   1. #if UNITY_IOS
   2.  
   3. using UnityEditor;
   4. using UnityEditor.Callbacks;
   5. using UnityEditor.iOS.Xcode;
   6.  
   7. public static class BitCodeHelperRevised
   8. {
   9.     [PostProcessBuild(1000)]
   10.     public static void PostProcessBuildAttribute(BuildTarget target, string pathToBuildProject)
   11.     {
   12.         if (target != BuildTarget.iOS) return;
   13.  
   14.         var projectPath = PBXProject.GetPBXProjectPath(pathToBuildProject);
   15.  
   16.         var pbxProject = new PBXProject();
   17.         pbxProject.ReadFromFile(projectPath);
   18.  
   19.         var targetGuids = new[] { pbxProject.GetUnityMainTargetGuid(), pbxProject.GetUnityFrameworkTargetGuid() };
   20.         pbxProject.SetBuildProperty(targetGuids, "ENABLE_BITCODE", "NO");
   21.         pbxProject.WriteToFile(projectPath);
   22.     }
   23. }
   24. #endif
2. After building in Unity, open Unity-iPhone.xcworkspace (I used to open Unity-iPhone.xcodeproj and didn't know why it wasn't working anymore, so it's important to note that you now need to run the workspace).
3. Ensure that nothing is using BitCode. Click on 'Unity-iPhone' in the left menu, then check every target and the Project. You can check this by clicking "Build Settings" in the menu and searching for "enable bitcode." If you see something using bitcode (true), change it to false.
4. After checking every target, click on 'Pods' in the left menu and do the same (check if all bitcodes are set to false).
5. Select 'Unity-iPhone' in the left menu, click on 'UnityFramework' under targets, then click on Build Settings and search for "library search path." Add the following:
   Code (CSharp):

   1. $(SDKROOT)/usr/lib/swift
   Code (CSharp):

   1. $(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)
   Huge thanks to @ImYuta for this tip.
6. Search for "Runpath Search Path" in the same place (UnityFramework -> Build Settings) and add this line:
   Code (CSharp):

   1. /usr/lib/swift
   Then drag it to the top of the list. Thanks to @masterton for this advice.

That's it! I hope this helps!

Worked for me on:
Unity 2021.3.24f
XCode 14.1

 

@pichikala I had been looking for a way of making it work and your steps did it for me ! Thanks a lot
Unity 2023.3.10f1
IronSource SDK 7.5.1
Xcode 15.0 on Sonoma.

 

In my case I did only first step from @pichikala after that I noticed that I don't have xcworkspace but only xcodeproj, also I had Podfile, all I did I opened terminal in build folder and run pod install, it took a while but after installing I got xcworkspace after that I tried to build from xcodeproj but build failed, after that I tried from xcworkspace and it worked perfectly also ads are working in build

 

What works for me is to disable bitcode everywhere and change minimum deployment from 8 to 10 for protobuf.

Important notes though
You got to open the proj/workspace so you can see pods if you have properly integrated them.

Unity often doesn't integrate pods well, different type of issues for which you manually have to enable certain things in files, for example UTF-8 encoding which you have to manually edit a document somewhere differently depending on your terminal (M1/intel). Or certain ruby versions/xcode versions not working. It is quite tedious to implement and I spent like 1 month on this
