Dropbox Sync API alternative

Using the Core API is the recommended approach. There are existing iOS and .NET (third-party) libraries, and we will be building new ones for API v2 over the coming months. A preview of our Swift SDK just went out yesterday: https://blogs.dropbox.com/developers/2015/05/try-out-swiftydropbox-the-new-swift-sdk-for-dropbox-api-v2/.

Is it even possible to sync with the CoreAPI or is it really just a way of uploading and downloading files while the user waits? Or are you taking the SyncAPI and adding some of the features we had to the CoreAPI? I only just finished adding and deploying the Dropbox Sync API into my app when I found out about the discontinuation of it. 4 months work affected by that. Now I need to find an alternative solution.

"Is it even possible to sync with the CoreAPI or is it really just a way of uploading and downloading files while the user waits?"

I'm not entirely sure what you mean. Syncing generally means uploading and downloading files as well as getting notifications when files change. The Core API does all of these things (and is in fact the same API that the Sync SDKs use under the hood).

Ok I see. Then is there an example somewhere or guide that says "if you were doing this or that in the Sync API, you should be doing this instead with the Core API?"

Not really. As new SDKs for API v2 come along, we'll probably be writing some more blog posts about how to use them to do common syncing tasks (like listening for changes). For now, I'd wait and watch the blog as the new API v2 develops.

Well most of the blog posts that I've seen about the v2 API are geared towards REST calls. I'm working with iOS and don't care much for the REST API. But I'll keep an eye open for it.

So far, the only SDK we've released (in preview) for API v2 is actually one for iOS (written in Swift): https://blogs.dropbox.com/developers/2015/05/try-out-swiftydropbox-the-new-swift-sdk-for-dropbox-api-v2/.

In the past you are often wrote that "new SDKs will come along". So, after the launch of v2 API in November 2015 it seems nothing happened right now. There are still just 4 new SDKs. What about an ObjC SDK for v2? Swift is new and buggy and not every developer wants to use it. ObjC is still around (and will be) on a very large code base. I really, really miss the Sync API (as so many others already mentioned).

When we can use a new and modern ObjC-SDK?

Thanks for the feedback! I don't have any news to share regarding a new Objective C SDK for API v2 though.

The official Objective-C SDK for API v2 has been released here:
