iOS开发，使用Pods安装Swift版第三方库报`use_frameworks!`错误，如何处理？
[!] Pods written in Swift can only be integrated as frameworks; this feature is still in beta. Add `use_frameworks!` to your Podfile or target to opt into using it.
解决方法：
platform:ios,’8.0’
pod 'AFNetworking'
pod 'MJRefresh'
pod 'XMLDictionary'
pod 'PureLayout'
pod 'iCarousel'
pod 'SnapKit'
pod 'RETableViewManager'
pod 'DZNEmptyDataSet'
pod 'SlackTextViewController'
pod 'MGSwipeTableCell'
use_frameworks!
