 ## Modernization - More Swifty
 
-As we go into 2022, it's a top priority for the Firebase team to improve
-usability and functionality for Swift developers. We welcome the community's
-input and contribution as we work through this.
-
-See the [Project Dashboard](SwiftDashboard.md).
-
-Please upvote existing feature requests, add new feature requests, and send PRs.
-* [Example Feature Request](https://github.com/firebase/firebase-ios-sdk/issues/8827)
-* [Example Pull Request](https://github.com/firebase/firebase-ios-sdk/pull/6568)
-
-See [Contributing.md](Contributing.md) for full details about contributing
-code to the Firebase repo.
-
-Thanks in large part to community contributions, we already have several Swift
-improvements:
-* Analytics
-  * Enabling [SwiftUI Screen tracking](https://github.com/firebase/firebase-ios-sdk/blob/main/FirebaseAnalyticsSwift/CHANGELOG.md)
-   automated view logging for SwiftUI apps
-* Firestore and RTDB
-  * Codable Support ([Firestore](https://github.com/firebase/firebase-ios-sdk/pull/3198),
-   [Database](https://github.com/firebase/firebase-ios-sdk/tree/main/FirebaseDatabaseSwift/Sources/Codable))
-   eliminated manual data processing
-  * [Property wrappers](https://github.com/firebase/firebase-ios-sdk/pull/8408) for Firestore collections dramatically simplified client coding
-* Storage
-  * Eliminated impossible states, provided new and improved async API usage via
-   [Result type](https://github.com/firebase/firebase-ios-sdk/blob/main/FirebaseStorage/CHANGELOG.md)
-   and [async/await](https://github.com/firebase/firebase-ios-sdk/blob/main/FirebaseStorage/CHANGELOG.md)
-   additions
-* ML Model Downloader
-  * Full [SDK implementation in Swift](https://github.com/firebase/firebase-ios-sdk/tree/main/FirebaseMLModelDownloader/Sources)
-* In App Messaging
-  * Vastly simplified usage from SwiftUI with
-   [SwiftUI modifiers](https://github.com/firebase/firebase-ios-sdk/pull/7496) to show messages and
-   [preview helpers](https://github.com/firebase/firebase-ios-sdk/pull/8351)
-
-### Phase 1 - Address Low Hanging Fruit for all Firebase Products
-* Swift API tests
-* async/await API evaluation, tests, and augmentation
-* Fix non-Swifty APIs
-* Fill API gaps
-* Better Swift Error Handling
-* Property Wrappers (Not necessarily low hanging, but can be high value)
-* Identify larger projects for future phases
-
-### APIs
-
-Continue to evolve the Firebase API surface to be more
-Swift-friendly. This is generally done with Swift specific extension libraries.
-
-[FirebaseFirestoreSwift](Firestore/Swift) is a larger library that adds
-Codable support for Firestore.
-
-Add more such APIs to improve the Firebase Swift API.
-
-More examples in the
-[feature requests](https://github.com/firebase/firebase-ios-sdk/issues?q=is%3Aopen+is%3Aissue+label%3A%22Swift+API%22).
-
-### SwiftUI
-
-Firebase should be better integrated with SwiftUI apps. See SwiftUI related
-[issues](https://github.com/firebase/firebase-ios-sdk/issues?q=is%3Aissue+is%3Aopen++label%3ASwiftUI).
-
-### Swift Async/Await
-
-Evaluate impact on Firebase APIs of the
-[Swift Async/await proposal](https://github.com/apple/swift-evolution/blob/main/proposals/0296-async-await.md).
-For example, Objective-C callback APIs that return a value do not get an
-async/await API automatically generated and an explicit function may need to be
-added. See these
-[Firebase Storage examples](https://github.com/firebase/firebase-ios-sdk/blob/main/FirebaseStorage/Sources/AsyncAwait.swift).
-
-### Combine
-
-Firebase has community support for Combine (Thanks!). See
-[Combine Readme](FirebaseCombineSwift/README.md) for usage and project details.
-
-## More complete Apple platform support
-
-Continue to expand the range and quality of Firebase support across
-all Apple platforms.
-
-Expand the
-[current non-iOS platform support](README.md#community-supported-efforts)
-from community supported to officially supported.
-
-Fill in the missing pieces of the support matrix, which is
-primarily *watchOS* for several libraries.
-
-## Getting Started
-
-### Quickstarts
-
-Modernize the [Swift Quickstarts](https://github.com/firebase/quickstart-ios).
-Continue the work done in 2020 and 2021 that used better Swift style, SwiftUI,
-Swift Package Manager, async/await APIs, and multi-platform support for
-[Analytics](https://github.com/firebase/quickstart-ios/tree/master/analytics),
-[ABTesting](https://github.com/firebase/quickstart-ios/tree/master/abtesting),
-[Auth](https://github.com/firebase/quickstart-ios/tree/master/authentication),
-[Database](https://github.com/firebase/quickstart-ios/tree/master/database),
-[Functions](https://github.com/firebase/quickstart-ios/tree/master/functions),
-[Performance](https://github.com/firebase/quickstart-ios/tree/master/performance),
-and
-[RemoteConfig](https://github.com/firebase/quickstart-ios/tree/master/config).
+We're continuing a long term journey to migrate from Objective-C to Swift.
