Resolution issue with different set of supspecs.

What did you do?

Hey there!
Encountered pods resolution issue.
Details below:

Consider following Podfile and .podspecs.

target 'App'
   pod 'A', :path => 'path/to/local/pod'
   pod 'B', :path => 'path/to/local/pod'

Pod::Spec.new do |s|
  s.name          = 'A'
  ...
  s.dependency 'Lib/ResourceA' # <~ Look here
  s.dependency 'Lib/ResourceB' # <~ Look here
end

Pod::Spec.new do |s|
  s.name            = 'B'
  ...
  s.dependency 'Lib/ResourceB' # <~ Look here
  s.dependency 'Lib/ResourceC' # <~ Look here
end

Then pod install will resolve it like so.
pod A depends on Lib
pod B depends on Lib
Lib depends on Lib-ResourceA, Lib-ResourceB, Lib-ResourceC
Everything is fine.

Now lets consider following example:

target 'App'
   pod 'A', :path => 'path/to/local/pod'
   pod 'B', :path => 'path/to/local/pod'

target 'IndependentTarget' # <~ Added target in the same xcodeproj. But don't link it into App
   pod 'A', :path => 'path/to/local/pod' # <~ Depend only on A.

Pod::Spec.new do |s|
  s.name          = 'A'
  ...
  s.dependency 'Lib/ResourceA' # <~ Look here
  s.dependency 'Lib/ResourceB' # <~ Look here
end

Pod::Spec.new do |s|
  s.name            = 'B'
  ...
  s.dependency 'Lib/ResourceB' # <~ Look here
  s.dependency 'Lib/ResourceC' # <~ Look here
end

What happens now?!
cocoa pods resolve dependencies in the following way.
Same:
pod B depends on Lib
Lib depends on Lib-ResourceA, Lib-ResourceB, Lib-ResourceC
Different:
pod A depends on Lib-ResourceA-ResourceB
Lib-ResourceA-ResourceB depends on Lib-ResourceA-ResourceB-A and Lib-ResourceA-ResourceB-B.

Being that A and B both linked to App target it leads to duplication of artefacts, resource and etc.

What did you expect to happen?

I would say that duplication of target A could be solution.
A-App
A-IndependentTarget
But it may lead to problems when IndependentTarget linked to App.

What happened instead?

Copypaste
pod B depends on Lib
Lib depends on Lib-ResourceA, Lib-ResourceB, Lib-ResourceC
Wrong:
pod A depends on Lib-ResourceA-ResourceB
Lib-ResourceA-ResourceB depends on Lib-ResourceA-ResourceB-A and Lib-ResourceA-ResourceB-B.
