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!

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; --h1-color: #333;

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.

UIWebView no bounce

You can switch off the bounce effect of a UIWebView using this script: for (id subview in webView.subviews) if ([[subview class] isSubclassOfClass: [UIScrollView class]]) ((UIScrollView *)subview).bounces = NO; Considering the Apple Review process it may be problematic that we make assumption of the inner structure of the UIWebView - but some apps have made it through...

Alpha Apps vs. App Unbundling

Aktuell wird viel über das Modell der "Alpha Apps" und "App Unbundling" gesprochen. Hier kurz eine Übersicht und meine 5 cents: Alpha Apps Die chinesische App WeChat geht noch weiter: Neben einem Messenger, vergleichbar mit WhatsApp, bietet sie einen Lieferdienst à la Lieferando, die Möglichkeit etwa das eigene Konto zu checken (wie sonst bei der Bank-App) und gleichzeitig die Chance etwa Promis zu folgen, wie es Twitter bietet. Solche Alpha-Apps können dadurch verschiedene Aspekte und Möglichkeiten des Internets verbinden und werden so zum idealen Zugangsportal zum Netz – so wie traditionell der Browser am Computer. Den Tod des Browsers bedeutet das aber noch lange nicht. Der Browser ist tot, es lebe der Browser! Wirtschafts Woche App Unbundling Unbundling steht für das Unterteilen von Apps oder verschiedener Funktionen in mehrere, eigenständige Applikationen. Aber nicht jede Unbundling Aktion wird positiv von Usern aufgenommen. Facebook Messenger

KSCrash

Another crash reporter? Why? Because all existing solutions fall short. PLCrashReporter comes very close, but not quite: It can't handle stack overflow crashes. It doesn't fill in all fields for its Apple crash reports. It can't symbolicate on the device. It only records enough information for an Apple crash report, though there is plenty of extra useful information to be gathered! As well, each crash reporter service, though most of them use PLCrashReporter at the core, has its own format and API. KSCrash is superior for the following reasons: It catches ALL crashes. Its pluggable server reporting architecture makes it easy to adapt to any API service (it already supports Hockey and Quincy and sending via email, with more to come!). It supports symbolicating on the device. It records more information about the system and crash than any other crash reporter. It is the only crash reporter capable of creating a 100% complete Apple crash report (including thre
