Summary: iOS 13 introduced a new design for `UISegmentedControl` and new APIs to control this. `[UISegmentedControl tintColor]` is now ignored. We try to maintain backwards compatibility so the appearance is as close as possible to iOS 12. Changelog: Fix `tintColor` on SegmentedControlIOS Reviewed By: shergin Differential Revision: D17905892 fbshipit-source-id: 964ac64c8543660929c43b427dce4f78094b1255
