We recommend using `initWithDefaults` and we should follow the recommendation. This change removes all usage of `init` within MDC components in order to let us remove that initializer from the public surface.

Context:
Due to changes in the Swift runtime over the past years, methods that are considered "optional" in Objective-C need to have @objc annotations in order for Objective-C to be able to perform `respondsToSelector:` invocations.
Problem:
Many of our examples had not annotated their `catalogShouldHideNavigation` methods with the `@objc` annotation, causing the Catalog to wrap the examples in a container app bar view controller. The reason most of these examples would implement `catalogShouldHideNavigation` is because they are managing their own navigation (e.g. to demonstrate AppBar functionality), so this would often result in duplicate AppBars appearing in the example.
The fix:
All `catalogShouldHideNavigation` Swift methods have been annotated with `@objc`.
Fixes https://github.com/material-components/material-components-ios/issues/7576
Fixes https://github.com/material-components/material-components-ios/issues/7578
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.
{MDC iOS} No longer using `-init` for Color Scheme.
Based on the discussions in go/mdc-ios-theming, we should not use the `-init` default initializer. Instead, we should use an explicit set of defaults.
Search regex: '\[\[MDCSemanticColorScheme alloc\] init\]'
Replacing all non-integral, single-precision floating point literals with double-precision values explicitly cast to CGFloat. For example, `0.1f` should become `(CGFloat)0.1`.
Regex used:
```
([0-9]*\.)([0-9]*?)([1-9]+)([0-9]*?)[fF]
```

We can now make use of @available throughout our codebase.
We support Xcode 9 and up, which includes the iOS 11 SDK. This means we can remove any guards for SDKs prior to iOS 11.
This was cleaned up by running a global find-and-replace with the following regular expression:
```
Find:#if defined\(__IPHONE_11_0\) && \(__IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_11_0\)\n(.+if \(@available\(iOS 11.0, \*\)\) \{(?:.|\n)*?)(?:#else(?:.|\n)*?)?\n#endif
Replace:$1
```
With some additional cleanup for stragglers that didn't match this pattern. Note that else clauses were intentionally dropped.
Closes https://github.com/material-components/material-components-ios/issues/4909
Many of our Swift examples are either missing imports or are importing all of
MaterialComponents. Both of these will cause failures during internal builds.
ButtonBar, FlexibleHeader, HeaderStackView, and NavigationBar are all implementation details of AppBar. While these components can be used on their own, in practice we expect most typical usage to rely on AppBar. FlexibleHeader is a bit blurry in that there is often value in relying on it solely, but because it is not a true concept in the spec and its behavioral demos largely overlap with AppBar's, it is now a dragons demo.
Pivotal story: https://www.pivotaltracker.com/story/show/156982162
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.
