Can't import Dropbox API into Swift

Then that sounds like something in the Build settings. You've got #import <Dropbox/Dropbox.h> in the bridging header...I assume the naming of the bridging header follows Apple's convention. You might try to import another objC header in your bridging header and just make sure it is, in fact, bridging. And if you open up the Dropbox.framework file in your project, do you see a Headers folder with 19-20 .h files in it, including DBAccountManager? An in your Target, General settings you have Dropbox, QuartzCore, SystemConfiguration, CFNetwork, and Security? (Some of these might not be needed for Dropbox, but it's what I'm using.) There could also be a build setting you need to turn on, but I'm not sure which one.
