How to link to TestFlight App in iOS

There are two things you need to do. First, check to see if TestFlight is installed. Then create a new link to your app. NSURL *customAppURL = [NSURL URLWithString:@"itms-beta://"]; if ([[UIApplication sharedApplication] canOpenURL:customAppURL]) {     // TestFlight is installed     // Special link that includes the app's Apple ID     customAppURL = [NSURL URLWithString:@"https://beta.itunes.apple.com/v1/app/978489855"];      [[UIApplication sharedApplication] openURL:customAppURL]; } This special https://beta.itunes.apple.com URL will be opened directly in TestFlight. Finally, if you are using iOS 9 (or later), you need to make an addition to your Info.plist to get the canOpenURL: method to work. If your app is linked on or after iOS 9.0, you must declare the URL schemes you want to pass to this method. Do this by using the LSApplicationQueriesSchemes array in your Xcode project’s Info.plist file. For each URL scheme you wan...

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!

In-App Purchase Receipt Validation on iOS

A vulnerability has been discovered in iOS 5.1 and earlier related to validating in-app purchase receipts by connecting to the App Store server directly from an iOS device. An attacker can alter the DNS table to redirect these requests to a server controlled by the attacker. Using a certificate authority controlled by the attacker and installed on the device by the user, the attacker can issue a SSL certificate that fraudulently identifies the attacker’s server as an App Store server. When this fraudulent server is asked to validate an invalid receipt, it responds as if the receipt were valid. iOS 6 will address this vulnerability. If your app follows the best practices described below then it is not affected by this attack. iOS Developer Library In-App-Klau jetzt auch im Mac App Store ( Heise )

CFPropertyList

The PHP implementation of Apple's PropertyList plist can handle XML PropertyLists as well as binary PropertyLists. It offers functionality to easily convert data between worlds, e.g. recalculating timestamps from unix epoch to apple epoch and vice versa. A feature to automagically create (guess) the plist structure from a normal PHP data structure will help you dump your data to plist in no time. github

Firebase App Indexing from Google for Android and iOS

Firebase App Indexing gets your app into Google Search. If users have your app installed, they can launch your app and go directly to the content they're searching for. App Indexing reengages your app users by helping them find both public and personal content right on their device, even offering query autocompletions to help them more quickly find what they need. If users don’t yet have your app, relevant queries trigger an install card for your app in Search results. App Indexing lets Google index your app just as if it were a website. For users with your app installed, deep links to your app - on Android or iOS - appear in Google Search results, allowing users to find exactly the right content within your app. In addition to driving re-engagement, App Indexing on Android will also surface install buttons for users who do not yet have your app installed. Since 1 in 4 appsare already being discovered through search, App Indexing is a simple and free method for acquiring new u...
