It looks like you are implicitly assuming that the OS will send you chunks of stream data that correspond to single, complete parsable chunks. That may have worked accidentally because that happened to be how they arrived in time, but it is definitely unreliable (as you found). What you should do in connection:didReceiveData: is buffer the data you received, and split it up yourself by looking for the delimiters that separate individual tweets, and then parse those individual tweets.
