CocoaPods installation failure when building for iOS

I recently reset one of the work Macs and after pulling one of our repos and trying to do a build, I've been getting an error about cocoapods. The project contains Facebook, so I'm use to getting a workspace file, however because of the error, the workspace file is not generated. The console error is as follows.

I have been trying various things, but so far, nothing has helped. I appreciate any suggestions on solutions to the issue. Thank you.

Unity 2019.4.30
Facebook SDK 11

Spoiler: Cocoapods Error

iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in an non-functional Xcode project.

After the failure, "pod repo update" was executed and succeeded. "pod install" was then attempted again, and still failed. This may be due to a broken CocoaPods installation. See: https://guides.cocoapods.org/using/troubleshooting.html for potential solutions.

pod install output:

I am getting exact thing in my project. Just installed Facebook SDK yesterday and get this error. I too have tried many things but nothing has resolved it. Spent countless hours on this so hoping someone has an answer. I just posted this about 30 minutes ago in same forum. When I find a solution I will update my thread. GL

 

Thanks. I haven't found a working solution. The project builds fine on another mac and I wonder if it's maybe using an older version of cocoapods, and maybe that helps it work. Only thing I can think of since the mac it's not working on was wiped and factory reset.

 

Hmmm, my mac has all the latest of everything too and its not building. What version of what needs to be reverted to what version for it to play nice who knows. I really wish all these version incompatibility issues would go away as these types of problems are the only thing that slows our development down. Maddening.

 

I agree. I don't know why this would break on a fresh mac setup. Luckily we have a few other macs at work, but if I were doing this at home with one mac, I'd be in trouble. I still don't have a solution. I've been trying to compare the old mac with the wiped mac to see what is different. So far, no luck.

Edit: The wiped mac was updated to 11.5.2 Big Sur.
The other two macs are on 11.4 still. Not sure if that is relevant.

 

So I got it to build without the pod error by deselecting "use shell to execute cocoapod tool" but then I get the "can't find FBSDKCoreKitImport.h"

I now just tried creating a brand new project in Unity's recommended version, installing only the latest FB SDK package, setting it up with my app ID and using their sample code to get just the id and username. Built it in Unity. Tried building it in Xcode and still get an immediate error "'FBSDKCoreKitImport.h' file not found. Even though this header file is found in the Pods directory of the build. Hate this stuff.

 

same issue for us as well, no solution is found so far;
Unity, help!

 

It looks like this is a Unity bug: somehow it can't run the pod install command correctly.
But there is a solution, you can install the pods manually!
1. Right-click on the folder with the assembled build and click the "New Terminal at Folder" there


2. It will open Terminal, write "pod update" and hit enter. As a result Unity-iPhone.xcworkspace should appear in the folder


3. Open in Xcode and enjoy the build!)


PS: Additionally, I encountered a problem with the latest Facebook SDK. Dependencies with version 11.0 are not collected in xcode. To fix this, change their version to 11.1.0
https://github.com/facebook/facebook-sdk-for-unity/issues/578#issuecomment-915959975

 

Yeah, I can run it manually, but that didn't fix the FB problem. I'll try the Facebook fix you listed though.
What doesn't make sense is why it works on other macs and just not the freshly restored mac. This bug really needs to be fixed.

Thanks for the info!

 

I have the same problem, we really need a fix for this.

 

Thanks a lot !
I struggled quite a bit with this problem and tried different solutions, but this actually solved it for me.

 

If anyone else is struggling with this error, I found a solution.
Check the version of cocoapods installed on your machine. This can be done with a terminal command

pod --version

. If version is 1.11.*, which was released in september (https://github.com/CocoaPods/CocoaPods/releases) and probably not compatible with Unity 2019, you should downgrade it to the latest 1.10.* stable version. Just run commands

sudo gem uninstall cocoapods

and

sudo gem install cocoapods -v 1.10.2

.
Hope it helps

 

Thank you so much, I struggled all day on this error and that fixed it !! I hate Cocoapods so much...

 

+1 appears to have fixed it for us also. Thanks! Feels like something so simple and makes sense why the other macs still work as they are probably still using the older cocoapods.

 

This solved it for me too.

 

thanks. it helped

 

Life saver, thanks

 

Thank you for help, that is work

 

thank you for help, this it's work for me

 

Uninstalling cocoapods on my mac to 1.10.2 resolved the issue.

I am wondering if there is a compatibility matrix for Unity and Cocoapods available online?

 

Thanks, this fixed the error message in Unity 2020.3.19f1.

 

I tried the above solution, but I am still getting the errors while building unity ios build in Xcode...

I am using Unity version 2019.4.27f1
I am using firebase sdk version 8.4.0
facebook sdk version 9.0.0
and Admob sdk version 5.0.0

I am not able to generate workspace file with ios Build in Unity.
I tried following command on mac through terminal to create workspace file
pod install

But it is also getting following error...

Could you please help me in this...

 

Yes Bro! 5 hours later with you I resolved this f... ussue) THX!

 

I'm using a VMware virtual machine for macOS Monterey.
So far, I have not been able to solve the problem in this way either. Now I will try to install other versions of cocoapods....
Have you solved the problem?

 

Yes, issue got solved. I am using Admob Ads in the project. Earlier, I was using older version of Admob Ads. Later, I installed newer Admob version and uninstalled older admob version. The error of cocoapods was coming due to some files of older admob ads. After I deleted those files, the cocoapods error was eliminated.

 

You, sir, deserve a medal!
You just saved me (I'm using Unity 2019.4.18f1)!
Thank you very much!

 

It worked for me, thanks for saving my time.

 

Holy S***, this worked! Two hours of fighting with this; thank you.

 

You, my friend, made it onto my list of cool people.
I was trying to fix my CI build for nearly two days now, thank you so much!

 

I was also having an issue and the following worked for me. When I uninstalled cocoapods and tried to reinstall, it kept generating an error. The following worked and resulted in the workspace file generation for me.

-Uninstall cocoapods: sudo gem uninstall cocoapods

-Upgrade ruby to 3.0.0

1. curl -sSL https://get.rvm.io | bash -s stable
2. close and reopen terminal
3. rvm install ruby@latest
4. rvm use ruby-3.0.0 --default

- Reinstall cocoapods: sudo gem install cocoapods

Hope this helps someone else.

 

I am using Unity 2021.3.9f1. This issue still exists... Manually installing Pod works, but I have to turn off the "Use Shell to Execute Cocoapod Tool" option in the External Dependency Manager. This way, building from Unity works like a charm.

 

For Unity 2021.3.9f1 I had to install latest cocoa pods using this command

Code (CSharp):

1. sudo gem install cocoapods -n /usr/local/bin

Else it would always give error. And also turn off the "Use Shell to Execute Cocoapod Tool" option in the External Dependency Manager.

 

My solution (that works with Unity 2019) is:

Don’t try to modify the system ruby. This causes more problems than it solves.
Don’t try to install other versions of ruby for Unity to use. It seems to only use the system version.
Don’t use any ruby managers like rbenv, chruby, brew, ruby-install, asdf, either by themselves or to install cocoapods.

For me, when installing cocoapods, I had to first switch xcode versions from my version of xcode (xcode-beta 13), to the command line tools, which use a different version of ruby.
I ran

Code (CSharp):

1. sudo xcode-select --switch /Library/Developer/CommandLineTools
2. sudo gem install cocoapods
3. sudo arch -x86_64 gem install cocoapods
4. sudo xcode-select --switch /Applications/Xcode-beta.app

to switch to cmd line tools ruby, install cocoapods on both the arm and x86 architectures, and switch xcode back to the normal place, so Unity can use it to create the xcworkspace file.

Please let me know if this is a bad idea!

 

My Solution is to update the Dependency Resolver to the latest version (1.2.174 at the moment).
From https://github.com/googlesamples/unity-jar-resolver

It already has the fix for the subject.



For me, it works like a charm.

 

I have the same problem and none of the above worked

Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "Firebase/Analytics":
In Podfile:
Firebase/Analytics (= 9.6.0)
None of your spec sources contain a spec satisfying the dependency: `Firebase/Analytics (= 9.6.0)`.

 

I was having issues with ffi wrong architecture. Found the solutions from this thread.

https://github.com/ffi/ffi/issues/864

Code (CSharp):

1. gem install --user-install ffi -- --enable-libffi-alloc

 

If you are on an M1 Mac the correct way to resolve this is to right click (option click) on your iOS project folder to which you just built, and choose "New Terminal at Folder." Then enter "arch -x86_64 pod install" in the command line. Everything should run / build fine now. The issue is Unity attempts to install pods for non-silicon Macs.

 

I got this issue when I upgraded only `Firebase/Analytics` and **not** the other firebase dependencies.

I had to upgrade all of my firebase dependencies together to get around it.

Also patrickreece's solution above with the xcode-select appears to work.

 

So I'm having a very frustrating time trying to figure out why Unity is adding Firebase targets to the podfile.
I have a project that no longer requires Firebase Dynamic Links or Firebase Database so I updated the project from 8.13.0 to 10.3.0. (Deleted all the firebase folders from the Unity project and then installed the ones I am still using from Import->Package Custom->Package
Every time I build now the build fails as it's added these 8.13.0 targets back to the Podfile in the builds root folder . Ive tried deleting them from the Podfile and doing pod repo update then pod install and it still adds them back.
It also adds them when I try to do a clean build to an empty folder

How do I tell Unity I don't want Dynamic Links or Database anymore?

Code (CSharp):

1. source 'https://cdn.cocoapods.org/'
2.  
3. platform :ios, '11.0'
4.  
5. target 'UnityFramework' do
6.   pod 'Firebase/Analytics', '10.3.0'
7.   pod 'Firebase/Auth', '10.3.0'
8.   pod 'Firebase/Core', '10.3.0'
9.   pod 'Firebase/Crashlytics', '10.3.0'
10.   pod 'Firebase/Database', '8.13.0'
11.   pod 'Firebase/DynamicLinks', '8.13.0'
12.   pod 'Firebase/Messaging', '10.3.0'
13. end
14. target 'Unity-iPhone' do
15. end
16. use_frameworks! :linkage => :static

 

I have this issue. I tried the M1 mac answer (after trying all the other suggestions .. thanks!) .

So I run arch -x86_64 pod install at the right location (builds folder).

The first error I get is this:

"[!] A dependency with an external source may not specify version requirements (Google-Mobile-Ads-SDK)."

Now, I can modify the podfile to remove google mobile ads (which I never wanted anyway).

Then running again produces this:

"
[!] Unable to add a source with url `https://cocoapods.mycompany.com/Specs` named `mycompany`.
You can try adding it manually in `/Users/matt/.cocoapods/repos` or via `pod repo add`."

I have no idea why it would be looking in what's clearly a default/template url "mycompany.com". So if anyone has come across that, lmk! I'll post any updates here.

Update: that's at the top of my podfile. No idea why. Will search for the correct specs url and replace it, fingers crossed.

Yep, the correct url is right beneath it. Now the command runs.

matt@matts-Air builds % arch -x86_64 pod install
Analyzing dependencies
Cloning spec repo `cocoapods` from `https://github.com/CocoaPods/Specs`

I re-opened XCode. This time it was able to attempt a build.

It still failed(!) But not due to the cocoapods issue Thanks to the M1 Mac answer above!

 

To install homebrew on M1 macs, I followed this guide here: https://mac.install.guide/homebrew/index.html

- important: After running the install command, Homebrew will run installation and will end by showing you a set of instructions titled "Next steps". Make sure you finish the installation by doing what those instructions at the end tell you to do.
