This is how I solve In my case, I had problem with BonMot package and I solved errors with following these steps. 1-I upgraded BonMot package with the latest version which was 6.0.0 2-The package requires minimum IPHONEOS_DEPLOYMENT_TARGET attribute to 11 and I changed it. Changing attribute may affect your project, in that case you need to upgrade all packages to 11 If you have hundred packages in your pod file you can add these line your podFile than run pod update $iOSVersion = '11.0' post_install do |installer|  # add these lines:  installer.pods_project.build_configurations.each do |config|   config.build_settings["EXCLUDED_ARCHS[sdk=*]"] = "armv7"   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion  end     installer.pods_project.targets.each do |target|       # add these lines:   target.build_configurations.each do |config|    if Gem::Version.new($iOSVersion) > Gem::Version.new(config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'])     config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion    end   end      end end Thanx
