| # DuplicatedFrameworksRemover.rb | |
| # Created by Wojciech Kulik on 14/09/2021. | |
| # | |
| # Description: | |
| # This code fixes warnings caused by linking the same frameworks in multiple targets. | |
| # | |
| # Sample warning: "objc[1111]: Class XXXX is implemented in both path/FrameworkName1 and path/FrameworkName2. | |
| # One of the two will be used. Which one is undefined." | |
| # Usage: | |
| # - Put this file next to your Podfile | |
| # - Add in the Podfile: | |
| # load 'DuplicatedFrameworksRemover.rb' | |
| # | |
| # post_install do |installer| | |
| # remove_duplicated_frameworks('Pods-YourMainTargetName', installer) | |
| # end | |
| def remove_duplicated_frameworks(app_pod_name, installer) | |
| test_targets = get_test_targets(app_pod_name, installer) | |
| puts "Detected test targets: #{test_targets}" | |
| puts "Removing duplicated frameworks from OTHER_LDFLAGS" | |
| targets = installer.aggregate_targets.select { |x| !test_targets.include?(x.name) } | |
| # Checks each pair of targets if they have common pods. Duplicates are removed from the first one's xcconfig. | |
| for i in 0..targets.size-1 do | |
| target = targets[i] | |
| remainingAppPodTargets = targets[i+1..targets.size-1].flat_map(&:pod_targets) | |
| target.xcconfigs.each do |config_name, config_file| | |
| # Removes all frameworks which exist in other pods | |
| remainingAppPodTargets | |
| .flat_map { |pod_target| get_framework_names(pod_target) } | |
| .each { |framework| config_file.frameworks.delete(framework) } | |
| # Saves updated xcconfig | |
| xcconfig_path = target.xcconfig_path(config_name) | |
| config_file.save_as(xcconfig_path) | |
| end | |
| end | |
| end | |
| def get_test_targets(app_pod_name, installer) | |
| installer.aggregate_targets | |
| .find { |x| x.name == app_pod_name } | |
| .user_project | |

| .select { |x| is_test_target(x) } | |
| .map { |x| "Pods-#{x}" } | |

| def is_test_target(target) | |
| target.build_configurations.any? do |config| | |
| target.build_settings(config.name)["TEST_TARGET_NAME"] != nil | |
| end | |
| end | |
| def get_framework_names(pod_target) | |
| frameworkNames = pod_target.specs.flat_map do |spec| | |
| # We should take framework names from 'vendored_frameworks'. | |
| # If it's not defined, we use 'spec.name' instead. | |
| # | |
| # spec.name can be defined like Framework/Something - we take the first part | |
| # because that's what appears in OTHER_LDFLAGS. | |
| frameworkPaths = unless spec.attributes_hash['ios'].nil? | |
| then spec.attributes_hash['ios']['vendored_frameworks'] | |
| else spec.attributes_hash['vendored_frameworks'] | |
| end || [spec.name.split(/\//, 2).first] | |
| map_paths_to_filenames(frameworkPaths) | |
| end | |
| frameworkNames.uniq | |
| end | |
| def map_paths_to_filenames(paths) | |
| Array(paths).map(&:to_s).map do |filename| | |
| extension = File.extname filename | |
| File.basename filename, extension | |
| end | |
