IOS 8.2 is in its fifth beta version, but that hasn't stopped Apple from releasing the first beta version of iOS 8.3 for developers.
Remember what's new in OS X 10.10.3? Some of them, like new Emojis and a new Google account registration screen, were also brought to iOS 8.3.
The new operating system allows the wireless connection of the CarPlay feature of iPhones / iPods touch to automotive systems, eliminating the need to connect the device to the car via a Lightning cable, in addition to providing indications in the codes that Apple Pay can reach China in soon.
Along with iOS 8.3 beta, Apple also released the Xcode 6.3 beta with Swift 1.2 (compilation 6D520o), this version brings several advances in the new programming language launched in 2014 by the company.
