    DivKit

    DivKit

    DivKit is an open source Server-Driven UI (SDUI) framework

    DivKit is an open source Server-Driven UI (SDUI) framework. It allows you to roll out server-sourced updates to different app versions. Also, it can be used for fast UI prototyping, allowing you to write a layout once and then ship it to iOS, Android, and Web platforms. DivKit is an excellent choice to start using server-driven UI in your project because it can be easily integrated as a simple view in any part of your app. At the starting point, you don’t need a server integration. You can include all JSON on the client-side to try it in a real-world application. Also, we’ve made a sandbox for you to experiment with. You can try different samples in the web editor and see the results on the web or in the Android demo app, both of which are available on Google Play. We’ll publish the iOS demo app shortly. The UI in the demo can be updated live: the sandbox connects to the demo app via web sockets.

    CardParts

    CardParts

    A reactive, card-based UI framework built on UIKit for iOS developers

    CardParts is the second-generation Card UI framework for the iOS Mint application. This version includes many updates to the original card part framework, including improved MVVM, data binding (via RxSwift), use of stack views and self-sizing collection views instead of sizing cells, 100% swift and much more. The result is a much simpler, easier-to-use, more powerful, and easier-to-maintain framework. This framework is currently used by the iOS Mint application and the iOS Turbo application. There are two major parts to the card parts framework. The first is the CardsViewController which will display the cards. It is responsible for displaying cards in the proper order and managing the lifetime of the cards. The second major component is the cards themselves which are typically instances of CardPartsViewController. Each instance of CardPartsViewController displays the content of a single card, using one or more card parts (more details later).
