podfile写法

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!
inhibit_all_warnings!

target '项目名称' do
#这里示例pod
pod 'MJRefresh', '~> 3.1.16'   

# Swift 版本声明
post_install do |installer|
  installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '5.0'
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
      end
  end
end

IPHONEOS_DEPLOYMENT_TARGET 这个参数最好有 不填的话 默认的版本 可能与上面的platform版本不一样，而产生很多警告
