✓ ATS enforces secure connections ✓ Affects ModernHttpClient,      NSUrlSession, WebViews ✓ Does not affect Xamarin HttpWebRequest

✓ Slide Over ✓ Split Screen (﴾true multitasking)﴿ ✓ Picture-‐in-‐picture

To support Slide Over or Split View your app must do the following: ●  Be built against iOS 9 (﴾or greater)﴿ ●  Use a Storyboard Launchscreen ●  User interface built with storyboard

using Autolayout and Size Classes (﴾or Xamarin.Forms!)﴿

●  Support all 4 iOS device orientations

✓ CoreSpotlight ✓ NSUserActivity (﴾Handoff & Siri)﴿ ✓ Web Markup

✓ AddressBook deprecated ✓ Contacts (﴾create/edit)﴿ ✓ ContactsUI (﴾read)﴿

✓ STACKS (﴾horizontal & vertical)﴿ ✓ Layout only (﴾no properties)﴿ ✓ Leading/Trailing (﴾not Left/Right)﴿ -‐ great for localization

✓ Right-‐to-‐left support ✓ Including UINavigationController ✓ UIStackView!

UITextAlignment.Natural;    Leading  &  Trailing  v  Left  &  Right  

✓ Re-‐ordering now super-‐easy

CanMoveItem  (view,  index)  MoveItem  (view,  source,  dest)  

✓ Safari-‐in-‐a-‐box

✓ demo
