I have solved the issue through this post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['EXPANDED_CODE_SIGN_IDENTITY'] = "" config.build_settings['CODE_SIGNING_REQUIRED'] = "NO" config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0' config.build_settings['CODE_SIGNING_ALLOWED'] = "NO" config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64" end end end
