Pods written in Swift can only be integrated as frameworks; add `use_frameworks!` to your Podfile or

若是在使用cocoapod時出現「Pods written in Swift can only be integrated as frameworks; add `use_frameworks!` to your Podfile or target to opt into using it. The Swift Pods being used are: ReactiveCocoa, ReactiveSwift, and Result」的錯誤的緣由是：多是要添加的這個庫 不支持swift致使 。

解決方法：在podfile裏面添加 use_frameworks！即：

platform :iOS, '8.0'

pod 'Alamofire', '~> 1.1'
pod 'Taplytics'
pod 'MBProgressHUD'
pod 'Atlas'

use_frameworks!

end
