iOS 11.2 and watchOS 4.2 are mostly bug-fix updates, but with one big new feature: the inclusion of Apple Pay Cash, an easy way to pay and request money from friends using your iPhone, iPad or Apple Watch.
iOS 11.2 beta 2
iOS 11.2 beta 2 includes a fix for the predictive text bug where typing the letter “i” can replace it with the uppercase letter “A” and a question mark symbol.
Apple on Monday seeded the second betas of iOS 11.2, watchOS 4.2, tvOS 11.2 and macOS 10.13.2 to developers. Registered developers can install the new betas from Apple’s Developer Center, or by using each platform’s respective over-the-air update mechanism.
