Xcode 7Mac

Xcode 7 Mac official version is a programming tool suitable for use in Mac systems. Xcode 7 The official Mac version has a new user interface, and the technology it is built on has been fully proven. And Xcode 7 Macs can also add Swift code or frameworks to existing apps and view documentation in Swift or Objective-C.

Things to note:

Sometimes you will encounter errors when downloading and installing Mac software. Now the editor of Huajun will sort out the more common error situations and provide answers. Friends who encounter errors can refer to the following solutions:

1. "The xxx software is damaged and cannot be opened. You should move it to the Trash"

2. "The xxx software cannot be opened becauseApple can't check if it contains malware"

3. "Cannot open... software because it is from an unidentified developer"

The solution is as follows:

1. Set up on your Mac computerOpen any source.

2. If the error cannot be resolved by opening any source, it means that the application is subject to Apple's restrictions on unsigned applications, and you need to bypass application signature authentication by executing command line code. Execute command bypassiosnotarizationGatekeeper.

3. If neither of the above two methods works, then you need toclosureSIPSystem integrity protection.

Xcode 7 Mac software features

      Full support for Swift programming

Xcode 6 introduces a new way of designing and developing applications for developers, with deep support for Swift programming. Developers can not only use 100% Swift code to create a brand new application, but also add Swift code to existing applications. or framework, and view the documentation 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 simple 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.
