Can you clarify if you're trying to install SwiftyDropbox, and if so, which version? The latest version is 5.1.0, and you can find the installation instructions here. Please follow those, and share what error(s) you're getting if that's not working for you. (That should also install the necessary Alamofire dependency for you automatically.)
By the way, CocoaPods v1.0.0 is relatively old, so you may want to upgrade that.
