Cocoapods: Cocoapods dependency issue

[tosbaha]

I am trying to create a Cocoapods library. My library will include Google-Mobile-Ads-SDK as dependency. I used following commands

pod lib create BannerViewController
 > my email address
What language do you want to use?? [ ObjC / Swift ]
 > Swift
Would you like to include a demo application with your library? [ Yes / No ]
 > Yes
Which testing frameworks will you use? [ Quick / None ]
 > None
Would you like to do view based testing? [ Yes / No ]
 > No  

then edited BannerViewController.podspec added following line

s.dependency 'Google-Mobile-Ads-SDK', '~> 7.0'

I tried to use pod lib lint BannerViewController.podspec

[!] BannerViewController did not pass validation, due to 1 error and 3 warnings.
You can use the `--no-clean` option to inspect any issue.

I tried to pod update in Example directory and got following error

[!] The 'Pods-BannerViewController_Example' target has transitive dependencies that include static binaries: (/Developer/BannerViewController/Example/Pods/Google-Mobile-Ads-SDK/GoogleMobileAdsSdkiOS-7.4.0/GoogleMobileAds.framework)

I don't know how can I add Google-Mobile-Ads-SDK to my development pod so that I can test my code locally. Cocoapods documentation is not clear. I am using Cocoapods 0.38.2

You have to integrate as a static library until google ships a dynamic framework for their pod.

[tosbaha]

Could you share the details of this process? I asked on SO as well but I didn't get any reply. I will really appreciate if you can direct me to web page that details how to include Google-Moblie-Ads-SDK. For example Google ads can be integrated easily by pod and using objc header file. Isn't there a way to integrate ad sdk to my developer project same way so that I can work on it test it and publish? I know this is not a support forum but as I said I am run out of options.

Don't use use_frameworks! in your Podfile, and lint using the ---use-libraries flag.

[tosbaha]

Sorry for opening this issue again. I just gave it a go today again. Still it doesn't work. I removed use_frameworks! and tried to lint it with pod lib lint --use-libraries I get again the samer error message Here are my files

BannerViewController.podspec

Pod::Spec.new do |s|
  s.name             = "BannerViewController"
  s.version          = "0.1.0"

# This description is used to generate tags and improve search results.

#   * Try to keep it short, snappy and to the point.

  s.description      = <<-DESC

  s.requires_arc = true

  s.resource_bundles = {
    'BannerViewController' => ['Pod/Assets/*.png']
  }
  s.dependency 'Google-Mobile-Ads-SDK', '~> 7.0'
end

Podfile

source 'https://github.com/CocoaPods/Specs.git'

target 'BannerViewController_Example', :exclusive => true do
  pod "BannerViewController", :path => "../"
end

target 'BannerViewController_Tests', :exclusive => true do
  pod "BannerViewController", :path => "../"


end

[segiddins]

Can you please share the output of pod lib lint --use-libraries --verbose? Thanks!

[tosbaha]

You said don't use use_frameworks! That is why I removed it from Podfile. I am really puzzled. So it means there is no way to use cocoapods to integrate Google-Mobile-Ads-SDK to my swift library?

[segiddins]

Ask Google to update to ship dynamic frameworks ¯_(ツ)_/¯

[Lucashuang0802]

Do we have a solution for this problem? So, we can't use a static library as a dependency to develop framework?

[orta]

No, this is a LLVM / iOS issue, not a CocoaPods one.

[nicorsm]

I'm following. I have the same issue with Google SignIn iOS library. This is the error from pod spec lint:

- ERROR | [iOS] unknown: Encountered an unknown error (The 'Pods' target has transitive dependencies that include static binaries: (/private/var/folders/1_/7bxg_52x3rg89wmdqy6fnkrc0000gn/T/CocoaPods/Lint/Pods/Google/Libraries/libGGLCore.a and /private/var/folders/1_/7bxg_52x3rg89wmdqy6fnkrc0000gn/T/CocoaPods/Lint/Pods/Google/Libraries/libGGLSignIn.a)) during validation.

[kunalbalani]

I have the same problem :(

[Lucashuang0802]

@kunalbalani use --use-libraries when you validate or submit to CocoaPods. And if you do it this way, you users can use use_frameworks! in Podfile.

[kunalbalani]

@Lucashuang0802 that worked. Thanks 👍

[wilddylan]

Hi, same issue. use use_frameworks! in your Podfile, do not use --use-libraries when lint.

[ElizaSapir]

Hey,

I have the same issue,

    - ERROR | [iOS] unknown: Encountered an unknown error (The 'Pods-App' target has transitive dependencies that include static binaries: (/private/var/folders/57/pv4_gcjx5pn3_0vht648bqsm0000gn/T/CocoaPods/Lint/Pods/GoogleAds-IMA-iOS-SDK/GoogleInteractiveMediaAds/GoogleInteractiveMediaAds-GoogleIMA3/GoogleInteractiveMediaAds.framework)) during validation.

tried --use-libraries it doesn't help.

can you give me a solution? for now below is my code from podspec:

s.subspec 'IMAPlugin' do |ssp|
    ssp.source_files = 'Plugins/IMA'
    ssp.xcconfig = { 'CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES' => 'YES',
                  'OTHER_LDFLAGS' => '$(inherited) -framework "GoogleInteractiveMediaAds"',
                  'FRAMEWORK_SEARCH_PATHS' => '$(inherited) "${PODS_ROOT}"/**',
                  'LIBRARY_SEARCH_PATHS' => '$(inherited) "${PODS_ROOT}"/**' }
    ssp.dependency 'GoogleAds-IMA-iOS-SDK', '~> 3.3'
end

Pod install works but lint doesnt work for me, how can i handle it?

Thanks!

Hi. Is there any workaround for this issue? It has been more than one year and I'm wondering if there is something else people haven't tried yet.

[paulb777]

The CocoaPods static_framework introduced in 1.4.0 enables pods to depend on static library framework CocoaPods like Google-Mobile-Ads-SDK.

[wuzeqin]

if these method still solve your problem ，try to clean your local CocoaPods cache(remove file xx/Library/Caches/CocoaPods/Pods)

[ZeRoB]

In the .podspec file, above the line:
s.dependency ...
Add:
s.static_framework = true

when using CocoaPods version 1.4.0 and above and everything should work fine!

[ravisankar-r]

Hi, adding s.static_framework = true worked for me. But can someone explain how that works, not clear on what that flag does. Thank you

[paulb777]

@ravika08 See the Static Frameworks section in the CocoaPods 1.4.0 announcement blog.
