Missing dependencies for IMSDeviceCenter

[jonasbark]

platform :ios, '9.0'

source 'https://cdn.cocoapods.org/'
source 'https://github.com/aliyun/aliyun-specs.git'
target 'testest' do
  pod 'IMSDeviceCenter'
end

The app can't be built due to Undefined symbol issues. Some of them can be fixed by adding:

  pod 'Reachability'
  pod 'CocoaAsyncSocket'

but it will still fail with

Undefined symbol: _OBJC_CLASS_$_IMSOpenSecurityGuardManager

It is unclear which dependency contains the IMSOpenSecurityGuardManager definitions.
