Xcode 7 feature introduction
Full support for Swift programming
Xcode 6 introduces a new way of designing and developing applications for developers, with deep support for Swift programming. Not only can developers use 100% Swift code to create a brand new application, but they can also add Swift code or frameworks to existing applications and view documents in Swift or Objective-C. Such as "Jump to Definition", "Open Quickly" etc. all work well in Swift, and even Objective-C header definitions render well in Swift syntax.
Real-time code effect preview
Now, developers are using Interface When Builder designs the interface, it can preview the code effect in real time. When the program is run, the custom objects will be displayed at design time. When developers modify the custom view code, the Interface Builder's design canvas will automatically update without any build and run operations.
In addition, the API it contains also supports IB Inspector adds parameters to quickly modify views, and developers can even pre-populate sample data views to make the interface more accurate. iOS scripts that support UIKit size classes allow developers to develop a single universal script for all iOS devices, which not only selects behaviors for specific device sizes or orientations, but also maintains interface consistency and is easy to maintain.
Added View Debugging function
Xcode 6 implements View, which has been highly anticipated by developers. Debugger. Debugging app UI is now as easy as a click, and developers can easily see why a view might be cropped or hidden, and inspect and debug constraints and other parameters in the Inspector. Of course, Xcode also includes other new debugging tools, such as debugging Gauge to monitor I/O usage, enhanced iCloud Gauge, etc., and the Debug Navigator will also display more useful information, including stack frame records and block queues.
