Rather than letting retailers spy on users' devices without their awareness, Apple introduced plans last year based on Bluetooth LE iBeacons, which allow users who want to participate in retail loyalty or product information programs to explicitly opt into them, using a retailer's app to allow access to the store's iBeacons.

But repeat visitor information was mainly gathered by keeping track of an iPhone's MAC address-the 12-character identifier that is broadcast when a phone is searching for nearby Wi-Fi networks." "Some of this tracking is done by installing video cameras in stores to count foot traffic. "Nomi sold a service to retail stores that allows them to track how many shoppers visit their stores, where they spend time inside the stores and how frequently they return," the report by Jason Del Rey noted. Nomi saw the writing on the wall in August, when Re/Code reported layoffs at the company after Apple announced that iOS 8 would enhance user's privacy by blocking third parties from tracking user's location using the WiFi signals that mobile devices send out as they browse for available networks.

Launching the full PCalc app from its Home icon, Spotlight search or via Siri is about as easy as pulling down Notification Center and scrolling to the PCalc widget.Īnother developer hit by Apple's evolving platform policies is Nomi, a New York startup that targeted "using Wi-Fi signals from phones to help retail stores track and analyze their customers."
It's not clear if this is a policy designed to prevent developers from overloading the Notification Center with slightly modified versions of their full blown apps, or if the change is in response to diagnostic reports that uncovered problems related to the calculator, or if it's just an arbitrary and capricious new rule created for no reason.Īpple has yet to publicly comment on why it asked PCalc to stop distributing the app with a separate widget. However, Apple is now saying no to widgets designed to do computational app-like tasks within the Notification Center panel. PCalc is an app, but the developer added a slimmed-down widget version that users can optionally install, and Apple initially approved the app and its widget extension. Functionality that makes heavy use of system resources is appropriate for an app, not an app extension." The system is likely to terminate such an extension because of memory pressure. "For example, a Today widget that runs a graphics-intensive game might give users a bad experience. "App extensions do not get top priority for shared resources," Apple states. While the documentation on App Extension widgets doesn't appear to specifically forbid iOS calculators (and Apple's desktop OS X includes a calculator widget), it does outline that widgets should perform lightweight tasks. For example, if your extension blocks the main run loop, it can create a bad user experience in another extension or app." "Your app extension doesn't own the main run loop, so it's crucial that you follow the established rules for good behavior in main run loops. Specific to Widgets, Apple's documentation describes App Extensions as "providing quick updates or enabling brief tasks - for example, posting updates on package deliveries, the latest surf reports, or breaking news stories."Īpple states that "Some extensions may have lower memory limits than others: For example, widgets must be especially efficient because users are likely to have several widgets open at the same time.

Apple introduced the App Extension architecture in iOS 8 and OS X Yosemite to enable developers to extend the functionality of a variety of system software functions, from Share Sheets to Photo Editing to Custom Keyboards and Widgets.
