Cocoapods: Duplicate symbols when framework target has a static dependency

Report

What did you do?

I have a project with two targets A and B. Target A is an iOS app, target B is a dynamic iOS framework. Both targets need FirebaseAnalytics dependency (which to my understanding is a static vendored library).

What did you expect to happen?

Have a correctly linked project where static dependencies of target B would be only present in target A's binary.

What happened instead?

No matter how I try to add the dependency, there are always two possible outcomes. One is that it compiles and runs, but all symbols from FirebaseAnalytics are reported to be duplicates contained in both target A and B. If I manually change the target A's xcconfig file (generated by CocoaPods) and remove -framework FirebaseAnalytics from OTHER_LDFLAGS it seems to work as expected.

The other outcome are just No such module 'FirebaseAnalytics' errors. That can be achieved by changing the Podfile to this:

platform :ios, '9.0'
use_frameworks!

abstract_target 'ProjectRoot' do
    pod 'FirebaseAnalytics'

    target 'SampleApp' do

      pod 'AFNetworking'
    end

    target 'SampleFramework' do
        inherit! :search_paths
      pod 'CocoaLumberjack'
    end

end

CocoaPods Environment

I tried both CocoaPods 1.3.1 and 1.4.0.beta.1. The following environment dump is from 1.3.1.

I have a new version of the workaround. It works when some static libraries are only used in the Application target, but not in the library target. Still not sure if it's a good idea to use this, but at this time we don't have much else to try.

post_install do |installer|
    applicationTargets = [
        'Pods-SampleApp',
    ]
    libraryTargets = [
        'Pods-SampleLib',
    ]

    embedded_targets = installer.aggregate_targets.select { |aggregate_target|
        libraryTargets.include? aggregate_target.name
    }
    embedded_pod_targets = embedded_targets.flat_map { |embedded_target| embedded_target.pod_targets }
    host_targets = installer.aggregate_targets.select { |aggregate_target|
        applicationTargets.include? aggregate_target.name
    }

    # We only want to remove pods from Application targets, not libraries
    host_targets.each do |host_target|
        host_target.xcconfigs.each do |config_name, config_file|
            host_target.pod_targets.each do |pod_target|
                if embedded_pod_targets.include? pod_target
                    pod_target.specs.each do |spec|
                        if spec.attributes_hash['ios'] != nil
                            frameworkPaths = spec.attributes_hash['ios']['vendored_frameworks']
                            else
                            frameworkPaths = spec.attributes_hash['vendored_frameworks']
                        end
                        if frameworkPaths != nil
                            frameworkNames = Array(frameworkPaths).map(&:to_s).map do |filename|
                                extension = File.extname filename
                                File.basename filename, extension
                            end
                            frameworkNames.each do |name|
                                puts "Removing #{name} from OTHER_LDFLAGS of target #{host_target.name}"
                                config_file.frameworks.delete(name)
                            end
                        end
                    end
                end
            end
            xcconfig_path = host_target.xcconfig_path(config_name)
            config_file.save_as(xcconfig_path)
        end
    end
end

FirebaseAnalytics is a static library framework and the iOS linker does not support static library dependencies for dynamic libraries.

One approach would be to make SampleFramework a static library framework as well with a CocoaPod static_framework with the feature introduced in 1.4.0 in #6811

@paulb777 Thanks for the info, I'll try to look for a way to use it differently.

Also, I made this stupid workaround, but it does seem to do the trick.

post_install do |installer|
    installer.aggregate_targets.each do |aggregate_target|
        if aggregate_target.name == 'Pods-SampleApp'
            aggregate_target.xcconfigs.each do |config_name, config_file|
                aggregate_target.pod_targets.each do |pod_target|
                    pod_target.specs.each do |spec|
                        if spec.attributes_hash['vendored_frameworks'] != nil or (spec.attributes_hash['ios'] != nil and spec.attributes_hash['ios']['vendored_frameworks'] != nil)
                            puts "Removing #{spec.name}"
                            config_file.frameworks.delete(spec.name)
                        end
                    end
                end
                xcconfig_path = aggregate_target.xcconfig_path(config_name)
                config_file.save_as(xcconfig_path)
            end
        end
    end
end

@TadeasKriz Be careful. The build error workaround is potentially pushing bugs to runtime where duplicate implementations can cause subtle incorrect behavior.

paulb777 picture paulb777 on 11 Oct 2017

@paulb777 With this workaround I don't see any warnings about duplicate implementations. I'm not sure why @loryhuz does. I might have missed something to look for (maybe another property instead of vendored_frameworks).

My question is, if I get no warnings about duplicate implementations, do I have them? I thought that this workaround will tell the linker to not link static libraries to the iOS app target (leaving them linked only to the library). Is this assumption wrong? Thank you for your insight.

TadeasKriz picture TadeasKriz on 11 Oct 2017

@paulb777 I've checked again, I still have like 3 warnings about duplicates (way way less than before and now the app started working as expected). I think that's because of the way I try to "detect" whether the library is static. Do you know any other way to tell if the dependency is a static library framework in the post_install? Thanks.

TadeasKriz picture TadeasKriz on 11 Oct 2017

I see it now. In some cases I'm removing wrong framework names. I need to remove them by the vendored framework name, not by the spec name.

@loryhuz I'll update the workaround in a few minutes. Still would love to find a better solution though.

TadeasKriz picture TadeasKriz on 11 Oct 2017

@loryhuz New version of the workaround, this time you shouldn't see any warnings about duplicate symbols.

@TadeasKriz Thanks for the help in this issue. This one seems more hard ! I can't compile with your new workaround, it's seems it's related to other static dependencies I have in my Podfile (like Facebook SDK), since I didn't see undefined symbols errors for Firebase:

Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_FBSDKClass", referenced from:

loryhuz picture loryhuz on 12 Oct 2017

What dependency is the FBSDKClass from? My guess is they use vendored_frameworks as well, but the framework is not a static library one, but dynamic.

And about this pod:
https://github.com/zendesk/zendesk_sdk_chat_ios
I didn't understand as I only reference it in my main app target, not in my Framework. I thought your post_install hook was only removing pod reference in the top of the file (abstract_target) to avoid duplicate but it's a total another stuff I guess ?

loryhuz picture loryhuz on 12 Oct 2017

It was removing all of them. It's probably a good idea to somehow check if they are in the framework as well, that didn't occur to me before. Let me check that.

                        end
                    end
                end
                xcconfig_path = aggregate_target.xcconfig_path(config_name)

Posting the workaround that I'm currently using in case it's helpful to anyone. This workaround uses the pre_install hook instead of the post_install hook. The issue occurs in the analyzer which runs before the pre_install hook. So you only have to change one thing if you make the change there. Using the example from https://github.com/CocoaPods/CocoaPods/issues/7126#issue-264583808, add the following to your Podfile.

pre_install do |installer|
  embedded_target = installer.aggregate_targets.find { |aggregate_target| aggregate_target.name == 'Pods-SampleFramework' }
  host_target = installer.aggregate_targets.find { |aggregate_target| aggregate_target.name == 'Pods-SampleApp' }
  host_target.pod_targets = host_target.pod_targets - embedded_target.pod_targets
end

Please let me know if you notice any potential issues with my workaround.

@hongrich Hi
In the example below AFNetworking also will be removed, that's not right.

platform :ios, '9.0'
use_frameworks!

target 'SampleApp' do
  pod 'AFNetworking'
end

target 'SampleFramework' do
  pod 'CocoaLumberjack'
  pod 'FirebaseAnalytics'
  pod 'AFNetworking'
end

I get a lots of similar warning on app start.
I start with @TadeasKriz 's solution, but does not disappeared all of my warnings.

I want to use 'couchbase-lite-ios', '~> 1.4.1', this pod contains an CBLJSViewCompiler.a file, what linked into my core lib, and into the main app.
A resolve it with edit @TadeasKriz 's code, with insert a remove for CBLJSViewCompiler.afile bellow.

post_install do |installer|
    sharedLibrary = installer.aggregate_targets.find { |aggregate_target| aggregate_target.name == 'Pods-SampleFramework' }
    installer.aggregate_targets.each do |aggregate_target|
        if aggregate_target.name == 'Pods-SampleApp'
            aggregate_target.xcconfigs.each do |config_name, config_file|
                sharedLibraryPodTargets = sharedLibrary.pod_targets
                aggregate_target.pod_targets.select { |pod_target| sharedLibraryPodTargets.include?(pod_target) }.each do |pod_target|
                    pod_target.specs.each do |spec|
                        frameworkPaths = unless spec.attributes_hash['ios'].nil? then spec.attributes_hash['ios']['vendored_frameworks'] else spec.attributes_hash['vendored_frameworks'] end || Set.new
                        frameworkNames = Array(frameworkPaths).map(&:to_s).map do |filename|
                            extension = File.extname filename
                            File.basename filename, extension
                        end
                        frameworkNames.each do |name|
                            puts "Removing #{name} from OTHER_LDFLAGS"
                            config_file.frameworks.delete(name)
                            config_file.libraries.delete("CBLJSViewCompiler")#<- What I insert
                        end
                    end
                end
                xcconfig_path = aggregate_target.xcconfig_path(config_name)
                config_file.save_as(xcconfig_path)

@hongrich Hi,
I have dependencies like :

    pod 'Firebase/Core'
    pod 'FirebaseUI/Auth'
    pod 'FirebaseUI/Google'
    pod 'FirebaseUI/Facebook'
    pod 'FirebaseUI/Phone'
    pod 'Firebase/Storage'
    pod 'FBSDKLoginKit'

and your workaround give me this error:

dyld: Library not loaded: @rpath/Bolts.framework/Bolts
  Referenced from: /.../SampleFramework
  Reason: image not found

Any idea?

I have a new version of the workaround. It works when some static libraries are only used in the Application target, but not in the library target. Still not sure if it's a good idea to use this, but at this time we don't have much else to try.

post_install do |installer|
    applicationTargets = [
        'Pods-SampleApp',
    ]
    libraryTargets = [
        'Pods-SampleLib',
    ]

    embedded_targets = installer.aggregate_targets.select { |aggregate_target|
        libraryTargets.include? aggregate_target.name
    }
    embedded_pod_targets = embedded_targets.flat_map { |embedded_target| embedded_target.pod_targets }
    host_targets = installer.aggregate_targets.select { |aggregate_target|
        applicationTargets.include? aggregate_target.name
    }

    # We only want to remove pods from Application targets, not libraries
    host_targets.each do |host_target|
        host_target.xcconfigs.each do |config_name, config_file|
            host_target.pod_targets.each do |pod_target|
                if embedded_pod_targets.include? pod_target
                    pod_target.specs.each do |spec|
                        if spec.attributes_hash['ios'] != nil
                            frameworkPaths = spec.attributes_hash['ios']['vendored_frameworks']
                            else
                            frameworkPaths = spec.attributes_hash['vendored_frameworks']
                        end
                        if frameworkPaths != nil
                            frameworkNames = Array(frameworkPaths).map(&:to_s).map do |filename|
                                extension = File.extname filename
                                File.basename filename, extension
                            end
                            frameworkNames.each do |name|
                                puts "Removing #{name} from OTHER_LDFLAGS of target #{host_target.name}"
                                config_file.frameworks.delete(name)
                            end
                        end
                    end
                end
            end
            xcconfig_path = host_target.xcconfig_path(config_name)
            config_file.save_as(xcconfig_path)

@TadeasKriz to implement this in my own project I assume I replace Pods-SampleApp with my app name and Pods-SampleLib with a library name and list all of them I want this to apply to?

I tried to insert the postinstall code, but I get:

[!] An error occurred while processing the post-install hook of the Podfile.
undefined method `build_configurations' for nil:NilClass

See also the next comment.

This is the error that I am getting when I run the app:

objc[99263]: Class PodsDummy_CocoaAsyncSocket is implemented in both /Users/user172615/Library/Developer/CoreSimulator/Devices/B4BCD2F3-8787-4F77-AA76-5DB45FA2EA7C/data/Containers/Bundle/Application/1E01783C-C884-4F5B-A253-28CF8E0E8C55/testProject.app/Frameworks/SquareReaderSDK.framework/SquareReaderSDK (0x110866c90) and /Users/user172615/Library/Developer/CoreSimulator/Devices/B4BCD2F3-8787-4F77-AA76-5DB45FA2EA7C/data/Containers/Bundle/Application/1E01783C-C884-4F5B-A253-28CF8E0E8C55/testProject.app/testProject (0x10c764238).

@rahamin1
Please try to change the
auto_process_target('testProject', 'SquareReaderSDK', installer)
to
auto_process_target(['testProject'], 'SquareReaderSDK', installer)

The main target should be an array.

@bestwnh Thanks! Missed that...
I see now that I am getting an error for something else:

undefined methodbuild_configurations' for nil:NilClass...`

Any idea what I am missing?

@rahamin1 It looks like the target name is incorrect. Maybe because your SquareReaderSDK is not import by CocoaPods? You can try to replace all two 'Pods-' to ''. It make the script no longer auto change the SquareReaderSDK to Pods-SquareReaderSDK.

You can also check the .xcconfig file to confirm the target name. The information is in my blog post link of the answer in stackoverflow.

@bestwnh can you send me an email? I would like to ask you something in an email...

Regarding the name of the pod (SquareReaderSDK), there is no such pod...
The installation process for this package (https://bit.ly/3d4SPA3) doesn't use cocoapods...

This is the error I am getting:

objc[7955]: Class PodsDummy_CocoaAsyncSocket is implemented in both /Users/user172615/Library/Developer/CoreSimulator/Devices/B4BCD2F3-8787-4F77-AA76-5DB45FA2EA7C/data/Containers/Bundle/Application/36574EF1-2F18-444B-B47B-F9FEA43DC7BE/plumpPlum.app/Frameworks/SquareReaderSDK.framework/SquareReaderSDK (0x10ed07c90) and /Users/user172615/Library/Developer/CoreSimulator/Devices/B4BCD2F3-8787-4F77-AA76-5DB45FA2EA7C/data/Containers/Bundle/Application/36574EF1-2F18-444B-B47B-F9FEA43DC7BE/plumpPlum.app/plumpPlum (0x10ac05238). One of the two will be used. Which one is undefined.

And this are the contents of the Pods directory:

I have uploaded a sample repo that demonstrates the problem to https://github.com/rahamin1/duplicate
