What am I doing wrong in Swift for calling this Objective-C block/API call?

Question

I\'m using RedditKit to integrate Reddit into an app, and in Objective-C I called the API as follows (and it worked fine):

    [[RKClient sharedClient] signI

It probably doesn't like your RKLink[]! type for collection as NSArray can theoretically contain any type of object. Try making collection an Array! or just an NSArray! to confirm.
