To use API v2 in iOS platform, we need an objective-C version

It is incredible that a company such as Dropbox would even go down this path. Supporting developers should be any companies #1 priority. Instead it sure seems like you and your team are focused on doing 'what you enjoy' instead of supporting the rest of us. Our team has chosen to pull all of our Dropbox support and only support Google Drive. We need a cross-platform way to access and manage files from a variety of devices and the lack of true Obj-C support is ridiculous. The two pages of complaints and explanations on why this is important only results in 'we underestimated, and it's not a priority'. This is an extreme disappointment to us and we feel that only by directing our clients to other services and moving our business away will the point be driven home. I'm sorry for your approach to this and your response so far has only been disappointing. Good luck with your push towards Swift, it sure looks like it's going well for you. I'm glad you get to use the Enums you like.
