Is there any API limits

Greg,

Here is an error message.

operation2 completion 609 744 ticktok 102

error  Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo={NSUnderlyingError=0x14ea8ec70 {Error Domain=kCFErrorDomainCFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, NSErrorFailingURLStringKey=https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings, NSErrorFailingURLKey=https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-2102, NSLocalizedDescription=The request timed out.}

So I ask for a shared link and NSURLSession.sharedSession() gives up waiting for a reply? This was at 609 links. I think these all existed, I simply sending a create to check at this point. If I actually create links the error must be happening sooner.  Sorry, I think your right, this looks like Swift/Network issue...
