UIToolbar and UINavigationBar supports AutoLayout

• Items are compatible with autolayout
• Zero-sized custom views must be avoided. Provide size,
  • Constraints with-height ||
  • Implement intrinsicContentSize ||
  • Connect your subviews via constraints

Layout Margins

• Easier insets handling. Supported on RTL as well. .left is aligned with .leading
  • directional layout margins
  • system minimum layout margins
• topLayoutGuide and bottomLayoutGuide is deprecated. Safe area is introduced. Inset could be modified with viewSafeArea insets.

UIScrollView

• frameLayoutGuide for UIScrollView stays fixed

UITableView

• seperatorInset in UITableView allows editing insets for readable area. This is always relative to the orientation meaning that will be resizing automatically for whole screen.

Swipe Actions

• New look and feel automatically for all table views
• Supports full swipe to delete for iOS 11-linked apps
• Leading and trailing swipe for different actions via delegate methods
