This PR is the last step in graduating the Navigation Drawer component from Beta to Ready. We have resolved all the outstanding issues in the Navigation Drawer Project here: https://github.com/material-components/material-components-ios/projects/85 and hotlist: 1230549 . The only outstanding issue is the unit tests ( #5466 , #5465 ) which were approved and are pending due to GitHub issues causing CI not to run. We are essentially migrating here the NavigationDrawer component from the MaterialComponentsAlpha podspec to the MaterialComponents podspec so it can be used publicly using the normal means of installing our Pod. This PR is blocked and can land once #5466 and #5465 land. Closes #5333
