1.设置相关

1.1选择Build setting 中Mach-type 为static
1.2.选中build Avtive Architecture Only 为NO
1.3.选中Build Library for distribution 为 Yes（会生产一个swift module interface的文件，用户点击你的头文件能跳转到声明方法）

2.文件的访问控制

2.1.需要暴露给OC的方法或者类需要加@objc public
2.2.需要暴露给Swift的方法或者类名public以上的访问权限就可以
2.3.默认是internal访问权限，不会暴露给外界，只在本module可见

3.打包发布

3.1 .打包Release模式的模拟器(arm64, x86_64, i386)和真机包(arm64, armv7)
3.2.查看framework支持的架构

lipo -info xxx.framework/xxx

3.3.合并framework为xcframework(包含多种架构的framework，上架AppStrore时候会自动选中合适的架构的framework),
命令：

xcodebuild -create-xcframework \
 -framework iphoneos/xxx.framework \
 -framework iphonesimulator/xxx.framework \
 -output "xxx.xcframework"

4.查看framework支持的架构和库类型(dynamic, static)

file xxx.framework/xxx

返回示例：
LebooSmartSDK.framework/LebooSmartSDK: Mach-O universal binary with 4 architectures: [arm_v7:current ar archive] [i386] [x86_64] [arm64]
LebooSmartSDK.framework/LebooSmartSDK (for architecture armv7): current ar archive
LebooSmartSDK.framework/LebooSmartSDK (for architecture i386):  current ar archive
LebooSmartSDK.framework/LebooSmartSDK (for architecture x86_64):    current ar archive
LebooSmartSDK.framework/LebooSmartSDK (for architecture arm64): current ar archive

current ar archive:说明是静态库，选择Do not embed
Mach-0 dynamically：说明是动态库，选择Embed

5.发布到cocoapod

#1.创建podspec文件  
pod spec create xxxx

#2.创建pod账号
pod trunk register 邮箱地址  '用户名' --verbose
接下来注册的邮箱地址会收到https://trunk.cocoapods.org/sessions/verify/xxxxx的验证地址，打开就算是注册成功。

#3.查看自己发布的开源库 
pod trunk me 

#4.验证podsped格式是否正确
pod lib lint xxxx.podspec --allow-warnings

#5.添加tag
git tag -a 版本号 -m "描述"

#6.发布到cocoapods  --skip-import-validation 爆出编译错误后加
pod trunk push xxxx.podspec --allow-warnings

podspec格式

#
#  Be sure to run `pod spec lint LebooSmartSDK.podspec.podspec' to ensure this is a
#  valid spec and to remove all comments including this before submitting the spec.
#
#  To learn more about Podspec attributes see https://guides.cocoapods.org/syntax/podspec.html
#  To see working Podspecs in the CocoaPods repo see https://github.com/CocoaPods/Specs/

  # ―――  Spec Metadata  ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  These will help people to find your library, and whilst it
  #  can feel like a chore to fill in it's definitely to your advantage. The
  #  summary should be tweet-length, and the description more in depth.
  #

  spec.name         = "LebooSmartSDK"
  spec.version      = "1.0.1"
  spec.summary      = "智能牙刷SDK"

  # This description is used to generate tags and improve search results.
  #   * Think: What does it do? Why did you write it? What is the focus?
  #   * Try to keep it short, snappy and to the point.
  #   * Write the description between the DESC delimiters below.
  #   * Finally, don't worry about the indent, CocoaPods strips it!
  spec.description  = <<-DESC
                       刷牙SDK
                   DESC

  spec.homepage     = "https://gitee.com/JamesLEO/leboo-smart-sdk"
  # spec.screenshots  = "www.example.com/screenshots_1.gif", "www.example.com/screenshots_2.gif"


  # ―――  Spec License  ――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Licensing your code is important. See https://choosealicense.com for more info.
  #  CocoaPods will detect a license file if there is a named LICENSE*
  #  Popular ones are 'MIT', 'BSD' and 'Apache License, Version 2.0'.
  #

  # spec.license      = "MIT (example)"
  spec.license      = { :type => "Apache", :file => "./LICENSE" }


  # ――― Author Metadata  ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Specify the authors of the library, with email addresses. Email addresses
  #  of the authors are extracted from the SCM log. E.g. $ git log. CocoaPods also
  #  accepts just a name if you'd rather not provide an email address.
  #
  #  Specify a social_media_url where others can refer to, for example a twitter
  #  profile URL.
  #

  spec.author             = { "fenglei" => "fengleicoder@163.com" }
  # Or just: spec.author    = "fenglei"
  # spec.authors            = { "fenglei" => "fengleicoder@163.com" }
  # spec.social_media_url   = "https://twitter.com/fenglei"

  # ――― Platform Specifics ――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  If this Pod runs only on iOS or OS X, then specify the platform and
  #  the deployment target. You can optionally include the target after the platform.
  #

  spec.platform     = :ios
  # spec.platform     = :ios, "10.0"

  #  When using multiple platforms
  spec.ios.deployment_target = "10.0"
  # spec.osx.deployment_target = "10.7"
  # spec.watchos.deployment_target = "2.0"
  # spec.tvos.deployment_target = "9.0"


  # ――― Source Location ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Specify the location from where the source should be retrieved.
  #  Supports git, hg, bzr, svn and HTTP.
  #

  spec.source       = { :git => "https://gitee.com/JamesLEO/leboo-smart-sdk.git", :tag => "#{spec.version}" }


  # ――― Source Code ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  CocoaPods is smart about how it includes source code. For source files
  #  giving a folder will include any swift, h, m, mm, c & cpp files.
  #  For header files it will include any header in the folder.
  #  Not including the public_header_files will make all headers public.
  #

  # spec.source_files  = "Classes", "Classes/**/*.{h,m}"
  # spec.exclude_files = "Classes/Exclude"

  # spec.public_header_files = "Classes/**/*.h"


  # ――― Resources ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  A list of resources included with the Pod. These are copied into the
  #  target bundle with a build phase script. Anything else will be cleaned.
  #  You can preserve files from being cleaned, please don't preserve
  #  non-essential files like tests, examples and documentation.
  #

  # spec.resource  = "icon.png"
  # spec.resources = "Resources/*.png"

  # spec.preserve_paths = "FilesToSave", "MoreFilesToSave"


  # ――― Project Linking ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Link your library with frameworks, or libraries. Libraries do not include
  #  the lib prefix of their name.
  #
  spec.vendored_frameworks = "LebooSmartSDK.xcframework"
  # spec.framework  = "SomeFramework"
  # spec.frameworks = "SomeFramework", "AnotherFramework"

  # spec.library   = "iconv"
  # spec.libraries = "iconv", "xml2"


  # ――― Project Settings ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  If your library depends on compiler flags you can set them in the xcconfig hash
  #  where they will only apply to your library. If you depend on other Podspecs
  #  you can include multiple dependencies to ensure it works.

  # spec.requires_arc = true

  # spec.xcconfig = { "HEADER_SEARCH_PATHS" => "$(SDKROOT)/usr/include/libxml2" }
  # spec.dependency "JSONKit", "~> 1.4"
