I followed the instructions at https://www.dropbox.com/developers/sync/sdks/ios to setup the SDK and https://blogs.dropbox.com/developers/2014/09/swift-apps-with-dropbox/ to import it into Swift with #import <Dropbox/Dropbox.h>. I get an unresolved identifier error for DBAccountManager in the AppDelegate, so it seems as if the framework isn't being imported. I made sure to add the other required frameworks. The Dropbox framework file is inside the project folder, and I created the URL scheme.
