How to set up the linkage and package method separately for each dependency with CocoaPods

CocoaPods doesn't allow the setup of the linkage and package method separately for each dependency. It is possible to setup the linkage method but only for the whole target like:

target :DynamicTarget do
    use_frameworks! :linkage => :dynamic
    
    pod 'DynamicPod' # This will be linked dynamically
end

target :StaticTarget do
    use_frameworks! :linkage => :static

    pod 'StaticPod' # This will be linked statically
end

Microsoft iOS team made a plugin to allow it: https://github.com/microsoft/cocoapods-pod-linkage

If you don't what to use the plugin you can still make it work on your own by using the CocoaPods pre_install hook.

pre_install do |installer|
  installer.pod_targets.each do |pod|
    if pod.name == "Podname"
      def pod.build_type
        Pod::BuildType.new(:linkage => :dynamic, :packaging => :framework)
      end
    end
  end
end

All possible BuildTypes are defined here https://github.com/CocoaPods/Core/blob/master/lib/cocoapods-core/build_type.rb.
