Material Components for iOS Files

In this minor release, we added opt-in feature from MDCShadowLayer to MDCShadow for several components, annotated APIs with tvOS availability, and fixed a variety of bugs on components.

New features

BottomSheet

MDCBottomSheetController has a new ignoreKeyboardHeight property to control BottomSheet's behavior when keyboard is present.

Chips

MDCChipFieldDelegate has a new delegate method chipFieldShouldEndEditing to match chipFieldShouldBeginEditing.
