The latest beta of iOS solves many bugs, but also contains a "wolf": the disappearance of Twitter in iOS sharing options. Without warning Apple has removed the link sharing a text or link to Twitter, a notable absence in both the system itself and in the Apple Apps comes as standard, like Photos or Safari.
This change could hide a big change from the App, Twitter itself, which could be enriched with new features making it much less necessary the old sharing function. There is also a precedent for this type of "withdrawal", with the case of YouTube, which had been removed from the version of iOS 6 before reappearing as an app "stand-alone"much richer performance and effective application very infrequently updated proposed standard.
Hope nonetheless that these changes does will impact negatively on some not particularly convenient features, as does hanging a picture with his iPhone to then switch on the fly on his Twitter account directly from sharing options. It is not certain that a remote application is in this case as convenient to use.
