Organisational Dysfunctions Mirrored as Architectural Complexity

Within this broad space, one sub-topic that frequently captures my attention is the relationship between organisational dysfunctions and their influence on software architecture. One pattern I’ve observed in large and smaller organisations is The Accountability Protection Buffer. This pattern arises when a team needs to shield themselves from problems inherited through services they depend on owned by other teams. Nick Tune @ Medium.com

Dark Theme (Dark Mode) in Android WebViews, WKWebViews and CSS

So your apps just implemented a shiny new dark theme and it’s looking 👌 There are lots of benefits to having a dark theme in your application, and having it consistent throughout your application allows for a great user experience. But what happens when the the user runs into a WebView in your app? Support: if (WebViewFeature.isFeatureSupported(WebViewFeature.FORCE_DARK)) { ... } Set: WebSettingsCompat.setForceDark(webView.settings, WebSettingsCompat.FORCE_DARK_ON) Current setting: val forceDarkMode = WebSettingsCompat.getForceDark(webView.settings) Joe Birch Assuming your question is asking how to change the colors of the HTML content you are displaying in a WKWebView based on whether light or dark mode is in effect, there is nothing you do in your app's code. All changes need to be in the CSS being used by your HTML content. CSS dark mode via :root variables, explicit colors and @media query: :root { color-scheme: light dark; ...

Server-driven UI (SDUI): Meet Zalandos AppCraft and AirBnB Lona

A short WTF: Joe Birch: SERVER DRIVEN UI, PART 1: THE CONCEPT Zalando seems to follow the SDUI principle as well - defining a common design language and construct the screens on the backend while displaying them natively on the clients. They even go one step further; they implemented a mighty toolset to enable non-technical stakeholders to define their own native app screens Compass: Web tooling to create screens and bind data Beetroot: Backend service that combines the screen layout definition with the data Lapis/Golem: iOS/Android UI render engines Crazy cool! Good job, guys (when you do an open-source release?) To even move faster a Flutter based UI render engine implementation was great!

PeekPop - Pre-iPhone 6S and 6S+

Peek and Pop Let your users preview all kinds of content and even act on it — without having to actually open it. Users can then press a little deeper to Pop into content in your app. Apple 3D Touch PeekPop Peek and Pop is a great new iOS feature introduced with iPhone 6S and 6S+ that allows you to easily preview content using 3D touch. Sadly, almost 80% of iOS users are on older devices. PeekPop is a Swift framework that brings backwards-compatibility to Peek and Pop. GitHub

Android with Kotlin, iOS with Swift, Kotlin Native, flutter.io, React Native, PWA, Xamarin, Hybrid - which way to go?

Currently there are tons of frameworks how to get your business model to the user... and in the app store Full Native Android with Kotlin, iOS with Swift Deepest integration Single way to make sure that you have no lock-in effect with a framework, and you are f**ed, when Apple or Google disallows the usage of a specific technology... Two teams required 2x code PWA (Progressive Web App) Write offline- and push-capable PWA with web-technologies only Some native features might require hybrid native development and bridging (like In-App purchases, AR, ...) In best case: One web team only for website and app Maybe some native specialists for special features Kotlin Native Develop a shared framework with or without UI using Kotlin Native Additional native code will most probably be required Big Android team, small iOS specialists flutter.io (React Native | Xamarin | ... ) One codebase (flutter: Dart, React Native: JavaScript, Xamarin: C#) Additional native code ...

Backend-driven native UIs

Backend-drive native UIs John Sundell Slide Share Using Back-End Design to Create Customizable Front-End Mobile Experiences By controlling the front end of mobile apps from the back end we can build customized experiences at runtime, creating cleaner interfaces and reducing load times. Nithin Rao UX Magazine The Hub Framework Welcome to the Hub Framework - a toolkit for building native, component-driven UIs on iOS ( no Android support released yet ). It is designed to enable teams of any size to quickly build, tweak and ship new UI features, in either new or existing apps. It also makes it easy to build backend-driven UIs. The Hub Framework has two core concepts - Components & Content Operations. Spotify LeeGo: Build UI without UIView LeeGo is a lightweight Swift framework that helps you decouple & modularise your UI component into small pieces of LEGO style's bricks, to make UI development declarative, configurable and highly reusable.

Database Driven UI - Meet Facebooks Messenger Re-Implementation: Project LightSpeed

Database-Drive UI - Database-driven Logic Rather than managing dozens of independent features and having each pull information and build its own cache on the app, we leveraged the SQLite database as a universal system to support all the features. Compared with the previous iOS version, this new Messenger is twice as fast to start and is one-fourth the size. We reduced core Messenger code by 84 percent, from more than 1.7M lines to 360,000. We accomplished this by using the native OS wherever possible, reusing the UI with dynamic templates powered by SQLite, using SQLite as a universal system, and building a server broker to operate as a universal gateway between Messenger and its server features. Native Code When building a new feature, it’s often tempting to build abstractions on top of the OS to plug a functionality gap, add engineering flexibility, or create cross-platform user experiences. But the existing OS often does much of what’s needed. Actions like rendering, tran...
