Xcode 6 beta 6 updates three tools and continues to improve the Swift Language
Apple released the sixth OS x Yosemite Developer Preview version for developers today. However, it has not released a new iOS test version, and OS X Yosemite DP 6 has no significant functional improvements. In Yosemite DP 6, in addition to the "Do Not Disturb Mode" Do Not Disturb in the notification center, multiple new icons are updated, such as battery, Font Book, Mission Control, and Notes. Although there is no new iOS test version, developers are more concerned with the update of Xcode 6 beta 6 and the changed content.
Xcode 6 beta 6 updated the Command Line, Hardware IO, and Graphics tools. From the comments of Xcode 6 beta 6, it is found that HomeKit Accessory Simulator is also added to the Hardware IO tool. Developers can download and use in https://developer.apple.com/downloads/index.action.
In Xcode 6 beta 6, it is worth noting that Swift and beta 6 have updated some new usage and solved multiple problems in previous versions. At The same time, Apple also updated The Swift Programming Language document, detailing The updated and deleted content.
