Using CocoaPods libraries is not a big deal. You can use them only by adding a bridging header in your swift project. Here is short example. I have install MBProgressHUD in Pods and using that inside Swift code.
You only need to Add a Bridging-Header between CocoaPod and your Swift project. When you try to add any Objective-C file in Swift project, XCode gives you option for this migration. When you confirm this, you are able to access Objective-C files in Swift.
