I have a project, and podfile like this

source '.git'

use_frameworks!
inhibit_all_warnings!

def commandPod
  pod 'DynamicColor'
end


target 'MyApp' do
  platform :ios, '13.0'
  commandPod
  pod 'JXPagingView/Paging'
  pod 'JXSegmentedView'
  pod 'LookinServer',             :subspecs => ['Swift'], :configurations => ['Debug']
end

target 'MyAppWidgetExtension' do
  platform :ios, '14.0'
  commandPod
  pod 'AttributedText',         :path => '../AttributedText'
end

touch_ios_14 = ['AttributedText']

post_install do |installer|
  installer.pods_project.targets.each do |target|
    puts "[post_install] target #{target}"
    target.build_configurations.each do |config|
      if touch_ios_14.include?(target.name)
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '14.0'
      else
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
      end
      config.build_settings['CODE_SIGN_IDENTITY'] = ''
    end
  end
end

then i run pod install, i got those message:

Multiple targets match implicit dependency for linker flags '-framework
DynamicColor'. Consider adding an explicit dependency on the
intended target to resolve this ambiguity.

Target'DynamicColor-iOS13.0'（in project 'Pods'）
Target 'DynamicColor-iOS14.0' （in project 'Pods')

so my question is: my MyApp supports 13.0 or above, but MyAppWidgetExtension project supports 14.0 or above, both of which require DynamicColor or other.

As the error states, you should Consider adding an explicit dependency on the intended target to resolve this ambiguity.

Try changing your pod file to

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

use_frameworks!
inhibit_all_warnings!

def commandPod(target)
  target.dependency 'DynamicColor'
end

target 'MyApp' do
  platform :ios, '13.0'
  commandPod(self)
  pod 'JXPagingView/Paging'
  pod 'JXSegmentedView'
  pod 'LookinServer', :subspecs => ['Swift'], :configurations => ['Debug']
end

target 'MyAppWidgetExtension' do
  platform :ios, '14.0'
  commandPod(self)
  pod 'AttributedText', :path => '../AttributedText'
end

touch_ios_14 = ['AttributedText']

post_install do |installer|
  installer.pods_project.targets.each do |target|
    puts "[post_install] target #{target}"
    target.build_configurations.each do |config|
      if touch_ios_14.include?(target.name)
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '14.0'
      else
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
      end
      config.build_settings['CODE_SIGN_IDENTITY'] = ''
    end
  end

  # Ensure explicit linking to avoid duplicate dependencies
  installer.pods_project.targets.each do |target|
    if target.name == 'DynamicColor'
      target.build_configurations.each do |config|
        config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'YES'
      end
    end
  end
end

And running

pod deintegrate
pod install --verbose
