## Introduction
The team is pivoting to using theming extensions so our examples should reflect the current best practices when using our APIs.
## The problem
We are using _Themers_ in some instances and some instances used a work around for the container scheme. In #6458 we added a Catalog wide container scheme.
## The fix
Remove _Themers_ for _Theming extensions_ and remove the workarounds for not having a catalog wide container scheme.
{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]
```

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.

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.

* MDCFloatingButton Color Themer added.
No support for icon color change inside color themer, this is left for user to handle for now.
Example added.

* Remove redundancy in tests and FabButtonColorThemer.
* Adding another example for color theming of a button.
* Setting secondary color for the test instead of primary since that's the value that's being used.
PR: https://github.com/material-components/material-components-ios/pull/3381
* [Buttons] Remove .largeIcon shape from FloatingButton (#2513)
The LargeIcon shape is not required, since the same behavior (support
for 36-point images) can be achieved by setting the contentEdgeInsets to
.zero.
Also updates one of the button examples to use a 36-point icon.
* [Buttons] Add extended FAB layout code (#2528)
Creating (internal for now) the required properties and layout code to support
the extended FAB. Unit tests to confirm the behavior and some minor
adjustments to existing values like default contentEdgeInsets values.
Implements #2495
* [Buttons] Expose Extended FAB properties (#2543)
Making the new properties public and also migrating away from simple
property setters to the new forShape:inMode: setters required for
UIAppearance support.
* minimumSize
* maximumSize
* contentEdgeInsets
* hitAreaInsets
Implements #2495
* [Buttons] Add basic Floating Button example (#2554)
Includes automatic adjustment of extended/normal layout depending on size
classes.
Demonstrates #2495
* [Buttons] Update README for Extended FAB (#2561)
The README includes usage examples for the FAB. Adding a section to
demonstrate how to configure the FAB in its different shapes and modes.
