这是因为你的pod只适用于你的Framework目标而没有测试。将测试目标添加到您的podfile。

It's because your pods only apply to your Framework target and no the tests one. Add the tests target to your podfile.

示例：

target 'MyFramework' do
  use_frameworks!
  pod 'Alamofire', '~> 4.5'
end

target 'MyFrameworkTests' do
  use_frameworks!
  pod 'Alamofire', '~> 4.5'
end
