use_frameworks!workspace 'MainProject.xcworkspace'    #工作台路径
project 'MainProject.xcodeproj'target 'MainProject' doproject 'MainProject.xcodeproj'pod 'Alamofire', '5.8.0'        pod 'Toast-Swift', '5.0.1'

endpost_install do |installer|installer.pods_project.targets.each do |target|target.build_configurations.each do |config|config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'endend
end

在MainProject目录下Pod install

在OneProject中创建Public 类
