Apple iTunes Auto-Renewables: Increase price of existing auto-renewable subscriptions while keeping existing subscribers at their current price

If you increase pricing, you can either maintain the current price for existing subscribers or apply the price change for all users. As you go through the workflow outlined in Making Price Changes to Auto-Renewable Subscriptions, you can choose whether to apply the price increase to all subscribers.

As of iOS 10.0, if you decide to increase prices for existing subscribers, Apple will notify the subscribers of the price increase, along with the date they will be charged the new price. They’ll need to agree to the new price before they're charged. If they don't agree, their subscription won't automatically renew.

Note that price preservation is only available when you increase pricing; not when you decrease pricing. Price decreases will be immediately applied to all subscribers paying a price higher than the one you set.

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!

UIDeviceOrientation vs. UIInterfaceOrientation

We stumbled upon a bug in one of our apps: - rotate the Homescreen to Landscape - go to some other screen - put the device on the table and go back - the homescreen is all messed up This behavior was similar with some other View controllers. The problem was in the viewDidAppear where the Interface should be rotated to Layout or Portrait- the UIDevice Orientation was used ( [UIDevice currentDevice].orientation ) an when you put the device on the Table the orientation of the Device is always "UIDeviceOrientationFaceUp". The Problem is that the Device Orientation could be FaceUp in Portrait AND Landscape mode so for this use-case this doesn't give you the proper information. instead determining the orientation by: UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) you should do this (at least in View controllers) and use the interfaceOrientation property: UIInterfaceOrientationIsLandscape(self.interfaceOrientation)

Alpha Apps vs. App Unbundling

Aktuell wird viel über das Modell der "Alpha Apps" und "App Unbundling" gesprochen. Hier kurz eine Ãœbersicht 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 ...

Unidirectional Data Flow Architecture (Redux) in Swift

In this post, I try to explain why using Redux with Swift is better idea [than MVVM]. What is Redux and Unidirectional Data Flow? Redux is a flux implementation but slightly better implementation, it makes your application’s state more predictable. It first came out in Javascript world as a predictable state container for JavaScript apps with the powerful javascript library React. Redux, simply makes your application’s state in single store object. So firing an action from your application/in view’s lifecycle state changes and your reducers for that action generate a new state. Seyhun Akyürek at Medium Replacing Redux in Swift with something better Being a fantastic framework for development doesn’t come without a cost. Every time you update internal state in Redux, the entire interface re-renders. This isn’t a huge deal in most cases. But eventually you might have a situation where one update to state needs to be instantaneous (like using the keyboard shortcut to move f...
