We need to add @objc annotations to colorScheme and typographyScheme instances in our Swift examples, because we moved to Swift 4.2, the respondsToSelector won't find `setColorScheme:` and `setTypographyScheme:` setters otherwise.
This is a follow up PR for #7166 adds @objc annotations to Swift catalogMetadata() methods, because the Swift 4 compiler no longer attempts to infer what methods should be visible to Objective-C. As a result of this change in the compiler, no Swift examples were showing up in Dragons after #7166. See this article: https://useyourloaf.com/blog/objc-warnings-upgrading-to-swift-4/ for additional context.
Removes the need to copy-paste stanzas from other files anymore as we'll rely on #4478 to generate the correct stanza for us instead.

Many of our Swift examples are either missing imports or are importing all of
MaterialComponents. Both of these will cause failures during internal builds.
Made colorScheme and typographyScheme properties in the class interfaces for all our examples.
Moved theming away from example inits and into viewDidLoad
Small update for slider example to allow it to grab the theming properly.
