1. 配置 .podspec 文件

Pod::Spec.new do |s|
  s.name             = 'XXX'
  s.version          = '1.0.0'
  s.summary          = 'XXX'
  s.description      = <<-DESC
    Xxx Swift Kit
    DESC
  s.license          = { :type => 'MIT', :text => <<-LICENSE
    MIT
    LICENSE
  }
  s.homepage         = 'https://github.com/xxxxxx/xxx'
  s.author           = { 'author' => 'emailname@126.com' }
  s.source           = { :git => 'https://github.com/xxxxxx/xxx.git', :tag => s.version.to_s }
  s.ios.deployment_target = '11.0'
  s.swift_version = '5.0'
  s.frameworks = 'UIKit', 'Foundation', 'AVKit', 'Photos', 'MediaPlayer', 'CoreLocation', 'CoreGraphics'

  # 对象
  s.subspec 'Object' do |ss|
    ss.resource     = 'Xxx/Classes/Object/*.xcassets'
    ss.source_files = 'Xxx/Classes/Object/*'
  end
  
  # 扩展
  s.subspec 'Extension' do |ss|
    ss.resource     = 'Xxx/Classes/Extension/*.xcassets'
    ss.source_files = 'Xxx/Classes/Extension/*'
  end
  
end

2. 验证 .podspec 文件

# 本地验证
pod lib lint xxx.podspec

# 远程验证
pod spec lint xxx.podspec

# 远程发布
pod trunk push xxx.podspec

# 查看账号
pod trunk me

# 注册账号
pod trunk register emailname@126.com
