For the 99 reddits app, I updated the UI to respect the “safe area” in iOS 11. One of the view controllers made use of a UIToolBar, which doesn’t look right on iOS 11 when I attach the bottom of the toolbar to the bottom of the safe area (see attached screenshot).
Filed as rdar://35633289 and on Open Radar.
On an iPhone X, when you add a standalone UIToolBar to a view controller and add a constraint from the bottom of the UIToolBar to the bottom of the its view controller’s safe area, the bar button items appear outside the UIToolBar. It works perfectly on an iPhone 8.
iOS 11.1 (15B87)
