iOS 8.3 beta 4 that was seeded to Apple's registered iOS developers last week has removed the long-standing option to share content to Twitter, according to our own findings a couple days ago that have since been confirmed by other users.
We've noticed something was afoot as the option to share to Twitter has gone missing from the Share sheet in iOS 8's stock Photos and Safari app.
Technically, the feature has not been removed entirely because it only disappears after installing Twitter's official iOS app in iOS 8.3 beta 4, as evidenced on the screenshots provided by our own Oliver Haslam.
Uninstall Twitter and it comes back.
It appears Apple plans to fix a long-standing keyboard issue which caused users to inadvertently tap the period key when aiming for the space bar in Safari. As noted by MacRumors, beta versions of iOS 8.3 feature a design change that should resolve the problem.
In 8.3, Apple has made the space bar longer on the keyboard that pops up when inputting text in Safari's omnibar, and the 'Go' button shorter. This should make it less likely for users to encounter accidental period key presses when typing out their web searches.
Following the public release of iOS 8.2 earlier this week with Apple Watch support, Apple is continuing development of iOS 8.3 by seeding the third beta on Thursday.
Developers registered with Apple can download the beta over-the-air on their iPhone or iPad or from the Developer Center. Apple says the update "contains bug fixes and improvements," but there's also new features.
