如何创建具有依赖关系的CocoaPod?

我正在使用命令生成的骨架 pod lib create .

我想创建一个依赖于其他两个pod的pod: PromiseKit 和 AWSS3 然后,我更改Podfile:

use_frameworks!

target 'ruawss3_Example' do
  pod 'ruawss3', :path => '../'
  pod 'AWSS3'
  pod 'PromiseKit', '~> 4.0'

  target 'ruawss3_Tests' do
    inherit! :search_paths

    pod 'Quick'
    pod 'Nimble'
    pod 'FBSnapshotTestCase'
    pod 'Nimble-Snapshots'
  end
end

和使用 pod install :

➜  Example git:(master) ✗ pod install

Using Nimble (5.1.1)
Using Nimble-Snapshots (4.4.0)
Using PromiseKit (4.1.0)
Using Quick (1.0.0)
Using ruawss3 (0.1.0)

Pod installation complete! There are 7 dependencies from the Podfile and 8 total pods installed.
➜  Example git:(master) ✗ pwd
/Users/brunomacabeusaquino/ApenasMeu/Dropbox (BEPiD)/Swift/ruawss3/Example

并在项目中添加此POD:

但是,我无法在Pods中编译文件>POD的开发>ruawss3>ruawss3>类>亚马逊3.swift。 Xcode找不到模块“AWSCore”。如何修复它?
