PodFrameworksIssue

Address how to avoid duplicating classes while using internal dynamic frameworks that embed static frameworks (frameworks that host a static library) or static library pods like in CocoaPods 1.5.x.

Related issues:

• CocoaPods/CocoaPods#5768
• CocoaPods/CocoaPods#7938

Compare setups

• Typical, that has duplication warnings
• Preferred, that works and deduplicates

Typical Setup

See the master branch.

MyApp
-- embeds MyAmazingFramework
-- embeds MyOtherAmazingFramework
-- depends on PodA

MyAmazingFramework
-- depends on PodA

MyOtherAmazingFramework
-- embeds MyAmazingFramework
-- depends on PodA

e.g.

workspace 'PodFrameworks.xcworkspace'

# Note: we use static libs for all pods
def shared_pods
  pod 'Switchboard'
end

target 'AppOne' do
  project 'AppOne/AppOne.xcodeproj'

  shared_pods
end

target 'MyAmazingFramework' do
  project 'MyAmazingFramework/MyAmazingFramework.xcodeproj'

  shared_pods
end

target 'MyOtherAmazingFramework' do
  project 'MyOtherAmazingFramework/MyOtherAmazingFramework.xcodeproj'

  shared_pods
end

Doing this, the lib is duplicated across both the frameworks and the app targets

Class PodsDummy_Switchboard is implemented in both MyAmazingFramework.framework/MyAmazingFramework and MyOtherAmazingFramework.framework/MyOtherAmazingFramework. One of the two will be used. Which one is undefined. Class PodsDummy_Switchboard is implemented in both MyOtherAmazingFramework.framework/MyOtherAmazingFramework and MyApp.app/MyApp. One of the two will be used. Which one is undefined.

Preferred Setup

See the deduped branch.

Make your internal frameworks into local pods and let CocoaPods link everything properly without duplicating static libraries.

workspace 'PodFrameworks.xcworkspace'

# Note: we use static libs for all pods
target 'AppOne' do
  project 'AppOne/AppOne.xcodeproj'

  pod 'Switchboard'
  pod 'MyAmazingFramework', path: 'MyAmazingFramework'
  pod 'MyOtherAmazingFramework', path: 'MyOtherAmazingFramework'
end
