What did you do?

1. Create a new Xcode 9.2 project "example" for iOS Swift
2. Change deployment target to iOS 9.0
3. Use a Podfile with:

platform :ios, '9.0'
use_frameworks!

abstract_target 'default_pods' do
    pod 'AFNetworking', '~> 3'
    target 'example'
end

4. Run pod install or pod update

What did you expect to happen?

AFNetworking is installed with a Deployment Target of iOS 9.0.

What happened instead?

AFNetworking is installed with a Deployment Target of iOS 8.0, which causes noticeable warnings like /Users/coeur/example/Pods/AFNetworking/AFNetworking/AFURLSessionManager.m:163:30: 'setResumingHandler:' is only available on iOS 9.0 or newer

Even if I manually change the Pods project Deployment Target to iOS 9.0, a simple pod update will reset it to iOS 8.0.

CocoaPods Environment

• CocoaPods 1.4.0.rc.1 (also reproduced with CocoaPods 1.3.1)
• Xcode 9.2 & High Sierra
