创建主程序：MainProject

目录结构：

sandbox设置成NO：否则Xcode15不能运行

创建多个子程序后的目录结构

在主程序的Podfile中添加代码

# Uncomment the next line to define a global platform for your project
platform :ios, '13.0'

  project 'OneProject/OneProject.xcodeproj'
end
 
target 'TwoProject' do
  project 'TwoProject/TwoProject.xcodeproj'
end


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

在MainProject目录下Pod install

在OneProject中创建Public 类
