Apple today seeded the fourth beta of an upcoming iOS 11.2 update to developers, four days after releasing the third iOS 11.2 beta, more than two weeks after releasing the first major iOS 11 update, iOS 11.1, and one day after the iOS 11.1.2 update.
Registered developers can download the new iOS 11.2 beta from Apple's Developer Center or over-the-air once the proper configuration profile has been installed from the Developer Center.
iOS 11.2 introduces Apple Pay Cash, Apple's new peer-to-peer payments service. Apple Pay Cash works through the Messages app and is designed to allow for quick person-to-person money transfers. It's available as a dedicated iMessage app in Messages, with cash transferred through the app.
Cash can be sent from a linked debit or credit card, while received cash is stored in an Apple Pay Cash card in Wallet that can be used for purchases or sent to a bank account.
On the iPhone X, iOS 11.2 adds a small bar underneath the icons located at the upper right side of the device on the Lock screen, which is designed to make the location of the Control Center gesture more clear. On the iPhone X, Control Center is accessed by swiping down from the top of the device.
In Control Center on all devices, there are two new informational pop-ups that are displayed when using the Wi-Fi or Bluetooth toggles. These pop-ups explain that Bluetooth and Wi-Fi are disabled temporarily rather than permanently when accessed from Control Center.
In iOS 11.2, there's support for faster 7.5W wireless charging for the iPhone X, iPhone 8, and iPhone 8 Plus. The faster speeds will be available when using third-party wireless chargers that support 7.5W charging or more.
The update also addresses an animation bug in the Calculator app that caused some numbers and symbols to be ignored when entered in rapid succession. The update removes the animations from the calculator app so calculations can be done quickly with no need to pause between entering numbers to obtain the correct result.
In addition to these bug fixes, iOS 11.2 introduces a new Now Playing option for controlling content on the Apple TV in Control Center, redesigned camera emoji, a new loading animation for Live Photos effects, and new Live wallpapers for the iPhone X, plus it adds a feature that lets developers offer new customers discounted introductory pricing for auto-renewable subscriptions on the App Store.
Update: Apple has also seeded a new version of iOS 11.2 to public beta testers.
